The MH2000-NO pump detector measures nitric oxide concentration using an electrochemical sensor. Seven order options cover four Standard ranges and three High Performance ranges. Choose the performance grade and measuring range together for the NO measurement task. One instrument is supplied with the selected sensor configuration and span.
Select the Grade and Measuring Range
| Configuration | Measuring ranges | Application limit |
|---|---|---|
| Standard | 0-20 / 50 / 100 / 250 ppm | Routine NO concentration measurement |
| High Performance | 0-500 / 1000 / 2000 ppm | Not suitable for flue-gas environments |
The High Performance options on this page cannot be used in flue-gas environments. Select the separate flue-gas-specific NO configuration when that application is required. Each measuring span belongs to an individual order option; the supplied instrument does not automatically switch between all seven versions. The grade name identifies the sensor configuration and does not establish a numerical accuracy value.
Portable Sampling and Alarm Controls
The internal pump delivers up to 1 L/min with ten adjustment settings. An LCD dot-matrix display shows the gas type, concentration, unit, battery level and time. English and Chinese interfaces are available. Concentration units include μmol/mol, ppm and mg/m³, with 1 μmol/mol equivalent to 1 ppm.
Two alarm stages have adjustable setpoints. Sound, light and vibration provide the alarm outputs, including an 85 dB sound alarm and blue/red alarm lights. Temperature and pressure compensation, self-check, zero calibration and factory reset are provided for instrument setup. Use the controls according to the supplied instructions for the selected NO sensor.

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.
