Here’s how:
Measure – turn the AutoTest Carbon Monoxide Tester on and the device immediately begins measuring CO levels.
Identify hazards – view live CO readings on the LCD display with audible/visual alarms indicating concentrations above 100 ppm.
Assess and respond – review measured CO levels and respond accordingly.
Change things like temperature unit, LCD backlight activation, minimum/maximum reading and more by pressing the relevant button.
Watch the video to see just how simple CO monitoring can be!
