Choose the MH2000-H2 pump hydrogen detector in the measuring span required for the sample. Six Standard electrochemical versions are available: 0-1000, 0-2000, 0-5000, 0-10000, 0-20000 and 0-40000 ppm. The internal pump draws a gas sample to the sensor, and the instrument displays hydrogen concentration on its LCD screen. Each range is a separate supplied version of this portable, single-gas H2 detector.
Select One of Six Hydrogen Ranges
The range selector identifies the maximum concentration span of the version supplied. Select a 1000, 2000, 5000, 10000, 20000 or 40000 ppm option for the expected concentration and the measurement procedure. One detector does not automatically cover every range shown on this page. Keep the target gas and the required measuring interval explicit when choosing the instrument.
Controls for Pump Sampling
Pump flow reaches up to 1 L/min, with ten adjustment settings. The LCD dot-matrix display presents the gas type, concentration, unit, battery level and time. The operating interface supports English and Chinese, and concentration can be displayed in ppm or mg/m³. Temperature and pressure compensation, self-check, zero calibration and factory-reset controls support instrument setup.
Two alarm stages have adjustable setpoints. Sound, light and vibration provide multiple alert outputs, including an 85 dB sound alarm and blue low-alarm/red high-alarm lights. Operate the selected H2 version according to its supplied instructions and the sampling procedure for the work.

Supplied Configuration and Optional Recording
The instrument has a rechargeable lithium-polymer battery and weighs 300 g. Data logging and PC export are optional and are not included in this base configuration. If recorded readings are needed, ask about the recording package before ordering. Sampling filters, drying accessories and high-temperature probes are separate choices; do not infer that they are included in every configuration.
Gallery photos illustrate the shared instrument housing. A connected cable does not indicate included PC export, and the carrying-case photo does not represent a two-detector order. Select the required hydrogen range as a separate order 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.
