- Kühlmittel, die aktuell in Kühlsystemen von Diesel-, Otto-, CNG-, oder Elektro-Fahrzeugen zum Einsatz kommen, erfüllen die folgenden Hauptaufgaben:
- rasche Wärmeab- und Wärmezufuhr (Kühlen und Wärmen - Temperieren)
- Korrosionsschutz aller im Kühlsystem und Thermomanagement benetzten Teile
- Frostschutz und Überhitzungsschutz
- Schutz gegen Ablagerungen
- Das dem Kühlmittel-Konzentrat beigemischten Wasser kommt eine bedeutende Rolle zu. Dieses zugesetzte Wasser sollte entmineralisiert sein.
- In Hybrid-, E- und BZ-Fahrzeugen kommen zunehmend isolierende Betriebsstoffe zum Einsatz. Der Einsatz von Hochvolt-Komponenten geht immer mit dem Einsatz von isolierenden Medien (Öle, Kühlmittel, etc.) einher, z.B. isolierende POE-Kompressorenöle in HV-Fahrzeugen.
- Selbst Kühlmittel die zunehmend in Thermomanagement-Systemen/ Kühlsystemen in HV- und BZ-Systemen verwendet werden, verfügen über diese isolierenden Eigenschaften.
- In Thermomanagement-Systemen von Brennstoff-Zellen und speziellen Hochvolt-Systemen kommen spezielle Ready-to-Use-Kühlmittel zum Einsatz die eine weitere Hauptaufgabe erfüllen.
- rasche Wärmeab- und Wärmezufuhr (Kühlen und Wärmen - Temperieren)
- Korrosionsschutz aller im Kühlsystem/ Thermomanagement benetzten Teile
- Frostschutz und Überhitzungsschutz
- Schutz gegen Ablagerungen
- elektrisch isolierende Eigenschaft (sehr geringe Leitfähigkeit =hohe Isolation)
- Der Einsatz von herkömmlichen Kühlmitteln ist in den hier genannten Anwendungen NICHT gestattet und führt zu irreparablen Schäden.
- Mischungen aus herkömmlichen Kühlmitteln und den Kühlmitteln mit sehr geringem Leitwert [µS/cm] sind ebenfalls nicht gestattet.
- Für diesen Einsatz sind mehrheitlich ready-to-use Kühlmittel im Einsatz, da (elektrisch isolierendes) deionisiertes Wasser in Werkstätten in der Regel nicht verfügbar ist. Die Hersteller-Informationen sind unbedingt zu beachten.
- Diese Kühlmittelmischungen sind deutlich teurer als herkömmliche Kühlmittel-Mischungen von z.B. Verbrennungsmotoren. Deshalb lohnt sich eine eingehende und dokumentierbare Messung des kritischen Leitwert-Parameters.
- Erhöht sich der Leitwert des Kühlmittels signifikant, so kann dies beispielsweise zu Kurzschlüssen innerhalb der Brennstoff-Zelle führen.
- Deswegen muss das Kühlmittel ersetzt werden, sobald ein erhöhter Leitwert im Kühlmittel gemessen wird.
- Üblicherweise ist der Ionentauscher des Kühlkreislaufes/ Thermomanagement-Systems zeitgleich mit dem Einsatz neuen Kühlmittels zu ersetzen.
- Für die fundierte Entscheidung, ob und wann das Kühlmittel sowie der Ionentauscher ersetzt werden müssen, ist das Messgerät LWM 01_LR der Autotestgeräte Leitenberger GmbH die optimale Lösung.
- Das Leitfähigkeitsmessgerät LWM 01_LR ist ein wahres Multitalent zur Überprüfung der Qualität von Kühlmittel-Lösungen.
- 4 Bereiche Leitfähigkeit: 200 µs/2 ms/20 ms/200 ms
- Eine 3-Punkt Kalibrierung sowie eine automatische Temperaturkompensation garantieren eine hohe Genauigkeit auch bei sehr schwankenden Messtemperaturen.
- Alle Werte können direkt auf die SD-Karte (1 ... 16 GB) gespeichert werden (nicht im Lieferumfang enthalten)
- Die gespeicherten Daten werden direkt als Excel-Datei auf der SD-Karte gespeichert (zur Auswertung wird keine Software benötigt)
- Hohe Genauigkeit
- Großes LC-Display
- Auf Wunsch mit Werkskalibrierzertifikat, für LWM 01_LR Medium FCC, 1 Messpunkt (€ 199.--)
- Artikelnummer : LWM 01_LR (100142_1)

Difficult/impossible to unscrew plastic cups (in order to recharge the vibrating/blinking device)
Color: Orange
Generally, I don't leave feedback on items purchased. However, in this case, I feel compelled to do so in hopes the mechanical engineers (of this product) will take my input to heart and ultimately modify it.
First the pros...
- I have 2 high-energy dogs (Jack Russell Terriers) who love their toys (e.g., chewing bones, tug-of-war, etc.) but usually get bored with them rather quickly.
- This interactive PetDroid ball, however, keeps them busy for a long time.
- In fact, my smaller dog (Max) knows its storage location and sits (as early as 6 AM) in front of the cabinet so that I give him "his ball". It keeps him busy for up to 1-2 hours at a time.
- Max is literally addicted to the PetDroid ball... his determinant play with it makes me laugh all the time.
Now, the cons...
- After several days of play, the exterior looks chewed up quite a bit. That's no problem though.
- Unfortunately, the interior "threads/grooves" of the two plastic cups (for closing/fasting) are very tiny.
- Thus, after an hour-long hard play, it is almost impossible to unscrew the 2 plastic cups in order to recharge the interior device.
- It appears the 2 cups somehow come off track and get realigned from the inside.
- At that point, I cannot unscrew the PetDroid ball in order to recharge the device.... and without the blinking/vibration, this toy is no longer fun for play.
- Ultimately, I had to place the bottom half of the ball into a vise and then use a plumbing wrench to untwist it.
Proposed Solution:
- Increase the size of the plastic cups' interior threads/grooves so that they won't get realigned/come off track.
- This would mitigate the current dilemma of NOT being able to unscrew the ball in order to recharge it.
In my view, this should be a relatively simple fix and significantly improve the durability of this product.
Thank you for your time.

Good fun and entertaining!
Color: Orange
A really fun interactive toy for your dog! It's pretty erratic and really gets him chasing it. The included soft cover was kinda hard to install and then it's hard to turn it off and on with the cover on, I feel like the cover didn't really improve it at all, sure it's louder without the cover but I feel like dog also likes it that way, he likes loud squeaky toys and this thing making a bunch of noise is appealing to him. We have mostly hardwood floors so it really gets moving, I'm sure on carpet it would be a bit quieter and maybe even a bit slower to move around but on hard smooth surfaces this things can really get zipping around abd get some speed to make him chase it. Overall a fun and entertaining toy.

Not the Fetch-Fest I Hoped For
Color: Orange
I had high hopes for the PetDroid Interactive Dog Ball, especially with the newly upgraded features and promises of durable, motion-activated fun. Unfortunately, it didn’t quite live up to expectations for my furry friend. Here’s why I’m giving it 2 stars.
Promising Features, Lackluster Results
The idea behind this toy is fantastic: a durable, motion-activated ball that would entertain my dog without much effort on my part. The ball is supposed to roll around on its own, keeping my dog engaged and active. However, in practice, it just didn’t capture my dog’s interest.
Durability
I will give credit where it’s due: the ball is well-made and seems durable. It can withstand some rough handling, which is great for more aggressive chewers. Unfortunately, durability doesn’t mean much if your dog won’t play with it in the first place.
Motion Activation
The motion activation feature is hit or miss. While the ball does move around as advertised, it didn’t seem to move in a way that intrigued my dog. He gave it a sniff, watched it for a minute, and then walked away, unimpressed. I tried multiple times to get him interested, but he simply wasn’t having it.
Lack of Engagement
The biggest issue is that the ball just didn’t engage my dog at all. It might be more suitable for a different personality type or breed, but for my pooch, it was a total flop. He’s usually quite playful and curious, so I was surprised by his lack of interest.
Final Thoughts
Overall, the PetDroid Interactive Dog Ball might work for some dogs, but it was a miss for mine. If your dog is easily entertained by automated toys, it might be worth a try. However, based on my experience, I can’t wholeheartedly recommend it.
Pros:
Durable construction
Motion-activated as advertised
Cons:
Did not engage my dog
Motion activation wasn’t intriguing enough
Might be more suitable for specific dog types or personalities
If you decide to give it a shot, just be prepared for the possibility that your dog might not find it as entertaining as you hope. For us, it’s back to the drawing board for a more engaging toy.

Pup Loves It, Some Other Notes
Color: Orange
We've had this for about six months and my 75 lb, 14-month-old German Shepherd pup LOVES IT. Her favorite is "Crazy Bouncing Mode." In fact, she doesn't care much for the normal mode. She chews it a lot - even drops it in her water bowl at times - and it's still going strong.
This is a great purchase. It's nice hands-off entertainment.
Do know that it is heavy compared to a normal ball - if your pup likes dropping it on the ground like mine does, it will land with a hard "thud," even with the included sleeve. Hopefully you don't have downstairs neighbors.
Also know that the cover that goes over the charging port is removable and your dog may choke on it if they chew it in just the right manner. Definitely only let the pup play with it while supervised.
All in all, great toy.
