Choose One CO2 Range for the Measurement Task
This portable carbon dioxide listing combines infrared sensing with internal pump sampling. Its ppm-range options are separate variants. Select the concentration span for the task, then compare the supplied sampling package and how the readings will be recorded. Carbon dioxide and carbon monoxide are different target gases; this is the CO2 product page.

Questions That Help You Choose
Which CO2 variant should I order?
Choose one of the listed concentration spans and confirm its supplied-model details; the highest span is not the range of every option.
What sampling package is required?
This listing describes an internal pump. Confirm the accessories needed for the measurement arrangement rather than assuming every sample accessory is included.
Do I need records from the measurement?
Compare the listed logging and USB transfer with the reporting task before choosing the package.
For the buying comparison, read single-gas vs. multi-gas comparison and pump vs. diffusion selection.
CO2-Specific Measurement or a Standard Four-Gas Monitor?
The portable multi-gas selection guide helps compare channel combinations. The standard LEL, O2, CO and H2S combination on the linked four-gas listings does not establish a CO2 channel. Keep the carbon-dioxide measurement requirement explicit when comparing instruments.
For the selected CO2 range, contact Mcooh with the required range and sampling package to clarify the supplied option and accessories before ordering. The pump/diffusion guide linked above explains the sampling choice; the range variants remain separate purchase options.

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.
Works as described.
