Choose a 0-1 ppm or 0-10 ppm version of the MH2000-NO ambient nitric oxide detector for low-concentration measurements. Both versions use an electrochemical sensor, internal pump sampling and 0.001 ppm resolution. This High Precision configuration is a portable, single-gas NO instrument intended for ambient-air measurement tasks within the selected span.
Low Ranges for Ambient-Air Measurements
The 0-1 ppm option has a lower maximum measuring span; the 0-10 ppm version covers a broader low-concentration interval. Resolution is 0.001 ppm on both options. Match the ordered span to the expected sample concentration and measurement procedure. Resolution describes the display increment and does not establish a detection limit or numerical measurement accuracy.
Each order supplies one instrument configured for its selected range. It does not automatically cover both versions. Select this ambient-air configuration for its stated application, and choose the separate flue-gas-specific version when the measurement task involves flue gas.
Display, Compensation and Alerts
The LCD dot-matrix display shows the gas type, concentration, unit, battery level and time. English and Chinese operating interfaces are available. Concentrations can be displayed in μmol/mol, ppm or mg/m³, with 1 μmol/mol equivalent to 1 ppm.
Temperature and pressure compensation, self-check, zero calibration and factory-reset controls support instrument setup. Two alarm stages allow the setpoints to be adjusted, with sound, light and vibration outputs. The sound alarm is 85 dB, and blue/red lights indicate the two alarm levels. Follow the instrument instructions for the selected low-range NO configuration.

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.
