CO-220 Carbon Monoxide Meter
The CO-220 Carbon Monoxide Meter makes it easy to take
quick and accurate measurements of CO levels. A large, backlit
LCD display shows CO levels from 0 to 1000 PPM. The MAX
Hold function stores and displays the maximum CO level.
1 year warranty.
CO-210 Carbon Monoxide Probe
As an accessory to a digital multimeter with dc mV inputs,
the Fluke CO-210 displays CO levels from 0 to 1000 PPM.
As a standalone device, the LED indicator and beeper trigger
with increasing frequency as the CO level rises.
1 year warranty.
CO-205 Aspirator Kit
Allows flue gas samples up to 371°C to be drawn with the
CO-210 or CO-220 for carbon monoxide measurement.
