The MH-1200H-S-CO measures carbon monoxide using diffusion sampling. Choose a 0-500, 0-1000 or 0-2000 ppm version before ordering; the three ranges are separate supplied configurations. Its concentration display and alarm records make this a product to compare when the task calls for a portable CO reading.
Choose the Configuration for Your Measurement
- Target measurement: Carbon monoxide (CO); this is not a carbon dioxide (CO2) meter.
- Sampling choice: Diffusion is the stated method. An external pump is an option, so confirm that package separately.
- Range choice: Choose the required span from the three SKU rows. The specification gives 0.1 ppm or 1 ppm resolution without mapping both values to each variant.

Questions Before Ordering
Which range should I select?
Select the span required by your measurement plan, then use the corresponding SKU. Do not assume a 0-500 ppm order can be switched into the 0-2000 ppm version.
Is a pump included?
The standard sampling description is diffusion. The source describes an external pump as optional; ask which pump, tubing and accessories are included if you need that arrangement.

My first impression after opening and installing batteries was that this meter is very well built considering the price and manufacturer. I had read some reviews stating that it's amp measurements were not accurate below 5 amps, I haven't seen any issues in any measurements I've taken, even side by side with my fluke meters. I've successfully taken accurate amp, voltage and continuity measurements with this ETCR6920B, the display is nice and legible. I haven't tried storing data and making transfers to a PC yet, the soft case is good enough for storage on a shelf and the test leads are of good quality and rated for 1000v. There's nothing bad to say about this meter especially when you consider the price, it's a really great meter.
