The MH2000-PH3 is an electrochemical phosphine gas detector with internal pump sampling. Select a Standard version from eight measuring spans, or a High Performance version in 0-2000 or 0-3000 ppm. The instrument measures PH3 concentration and presents the reading on an LCD dot-matrix display.
Choose the Performance and Measuring Span
Standard options are 0-5, 0-20, 0-50, 0-100, 0-500, 0-1000, 0-2000 and 0-3000 ppm. High Performance options are available only in 0-2000 and 0-3000 ppm. Choose both the performance grade and range when ordering; a higher upper measuring limit does not by itself identify a different performance grade.
The 2000 and 3000 ppm versions in either grade are single-gas configurations. This product measures phosphine only. Each ordered instrument has its selected span; the range menu does not represent interchangeable measuring ranges on one unit.
Sampling and Operator Controls
Ten suction levels provide pump adjustment, with flow up to 1 L/min. The interface supports English and Chinese. Concentration units can be switched between µmol/mol, ppm and mg/m³; 1 µmol/mol equals 1 ppm.
Two-stage sound and light alarms use adjustable setpoints, with vibration also available as an alarm output. Self-check, zero calibration and factory reset support setup. Temperature and pressure compensation are included as instrument functions. Use the supplied instructions for the selected PH3 configuration and measurement procedure.

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.
