The MH2000-H2 Low Range detector measures hydrogen concentration using an electrochemical sensor and an internal sampling pump. Choose a 0-10 ppm or 0-20 ppm version, both with 0.001 ppm resolution. This is a portable, single-gas H2 configuration for low-concentration measurement tasks that fit one of these spans. Select the measuring range when ordering; one instrument is supplied with the selected version.
Two Low Measuring Ranges
The 0-10 ppm option has a lower maximum measuring span, while the 0-20 ppm option covers a broader low-concentration interval. Both offer the same stated 0.001 ppm resolution. Match the required hydrogen range to the concentration expected in the sample and the measurement procedure. A detector ordered in one range does not automatically switch to the other version.
Sampling and On-Instrument Controls
The pump provides up to 1 L/min flow and ten adjustment settings. The LCD dot-matrix display shows the gas type, concentration, unit, battery level and time. English and Chinese interfaces are available, and hydrogen concentration can be displayed in ppm or mg/m³.
Two alarm stages have adjustable setpoints, with sound, light and vibration outputs. The sound alarm is 85 dB; blue and red lights indicate low and high alarms. Temperature and pressure compensation, self-check, zero calibration and factory-reset controls support instrument setup. Follow the supplied instructions for the low-range H2 configuration and the procedure used for the measurement.

Recording and Sampling Options
Data logging and PC export are optional and are not included in this base configuration. Where stored records are required, ask about the recording option before ordering. Sampling filters, drying accessories and high-temperature probes are separate package choices; their suitability and inclusion depend on the intended arrangement.
The instrument weighs 300 g and uses a rechargeable lithium-polymer battery. Gallery photographs illustrate the shared pump-detector housing, including views with a carrying case. The case image does not represent a two-instrument package, and a connected cable does not establish that PC export is included.

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.
