Check CO levels up to 999ppm with the push of a button using Model
CO15. An audible alarm indicator will continuously beep starting at 25ppm (preset warning level - value can be adjusted) and the display will flash until the CO level goes down to normal range. A backlight on the display can be used for low light areas. The meter comes complete with batteries, wrist strap, and pouch.
Applications:
- Ambient air safety checks on residential appliances - HVAC service on furnaces and hot water heaters - Home inspections - Industrial environments where the accumulation of CO is possible |
