Questions That Help You Choose
Is the listed measuring span enough for the task?
Compare the span and resolution in this model’s table with the reading you need; this page does not offer the other models’ range variants.
Do I need pump sampling?
A pump arrangement is not stated in this listing. Compare the SKY2000 page if the buying requirement includes an internal pump.
Which display and alarm functions matter?
Compare the listed concentration display and adjustable alarm with the task; do not assume the data-download functions of another NH3 model.
For the buying comparison, read ammonia detection for refrigeration tasks and single-gas vs. multi-gas comparison.
Compare pump-sampling NH3 option.
Need a Different Range or Sampling Arrangement?
Compare the MH-1200H-S-NH3 diffusion detector when separate range variants or its optional external-pump arrangement are relevant. The SKY2000 alternative linked above lists an internal pump. These are configuration differences to compare; they do not establish that a pump or range option is available on this AR8500 SKU.

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.
