Selection & Use Notes
Select the gas type and measurement range to match the intended hazard and site procedure. Because the instrument uses diffusion sampling, the target gas must reach the sensor opening. Alarm settings, calibration and operating checks should follow the configured sensor documentation and the safety procedures for the workplace.
Compare the Relevant Alternative
The pump single-gas family also offers 14 named gas options but draws the sample through an internal micro pump. This OLED product relies on diffusion and has a different housing/display arrangement. Compare sampling method first, then the selected gas row on each page.

Questions Before Ordering
Can I select HCN, HCl, NO or SO2 here?
All four appear in the current gas selector. Each is a separate purchase configuration; their range and sensor-response values must be read from the corresponding product row.
Should I use a general response time for every sensor?
The source includes gas-specific response figures. Compare the chosen sensor's row rather than applying the general figure to every gas option.

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.
