Klein Tools Gas Tester ET110 Carbon Monoxide Detector (0 to 1000 ppm STEL Monitoring Backlit LCD Pouch Air Quality HVAC Diagnostic Tool)

Scan Furnace Exhaust Ports and Monitor Short Term Exposure Boundaries Instantly with Dual Alert Indication Logic

Shop the Klein Tools ET110 carbon monoxide detector gas meter engineered to satisfy the toxic containment auditing requirements of mechanical ventilation systems. This ambient air quality scanner isolates unsafe combustion leakage profiles across an operational tracking range from 0 to 1000 ppm. Running an advanced microchip that checks short-term exposure limit parameters, the tool incorporates a dual audible acoustic buzzer and escalating visual flashing indicators pre-set to trigger at 35 ppm and 200 ppm boundaries to guarantee inspector safety inside de-energized residential utility enclosures.

Best Used For:

• Furnace Exhaust Auditing: Probing direct fuel-burning appliance vent configurations to trap carbon monoxide gas leaks creeping past structural seams.
• Boiler Plant Monitoring: Running atmospheric tracking sweeps inside gas-fired commercial spaces to verify short-term exposure compliance standards.
• Ambient HVAC Certifications: Surveying indoor ventilation streams for variable trace particulate accumulation loops to balance workplace health protocols.

Key Performance & Safety Features

• Precision Concentration Grid: Direct sampling hardware measures gas volume parameters cleanly from 0 up to 1000 ppm with real-time tracking accuracy.
• Escalating Visual Matrix: Onboard safety alert nodes change signal pulses dynamically from a low 35 ppm warning to a high-tier 200 ppm warning.
• Short-Term Exposure Logic: Programmed STEL tracking calculation scripts monitor running average shifts to intercept rising toxic saturation events.
• Backlit Digital Monitor: High-definition liquid crystal interface populates illuminated value fields to clear workspace viewing obstacles inside dark basements.
• Auto Power Conservation: Integrated internal clock timer routine kills tool activity after 20 minutes of idle status to preserve field battery life rows.

What's Included

• ET110 Carbon Monoxide Detector
• Protective Padded Carrying Pouch
• Four AAA Alkaline Batteries
• Set of User Instructions

Technical Specifications

Pro-Tip: When examining structural heating loops, verify your background air values outdoors or in a completely uncompromised zone before initiating internal boiler room sweeps; establishing this clean baseline values stabilizes sensor accuracy.
