Choose an ammonia detector around the required NH3 range and sensor configuration. The MH2000-NH3 uses an internal sampling pump to draw a gas sample to its electrochemical sensor. Standard options cover six ranges from 0-100 to 0-5000 ppm; the High Precision configuration uses a CITY sensor and offers separate 0-50, 0-100 and 0-1000 ppm versions. Select the configuration and range together when ordering. Each option is one detector with its selected measuring span.
Choose the Sensor Configuration and Range
| Configuration | Available measuring ranges |
|---|---|
| Standard | 0-100 / 200 / 500 / 1000 / 2000 / 5000 ppm |
| High Precision (CITY) | 0-50 / 100 / 1000 ppm |
Both configurations measure ammonia. A 0-100 ppm Standard option and a 0-100 ppm High Precision option are different sensor configurations, even though they share a measuring span. Choose the span for the expected concentration and measurement task; the maximum available range is not the range of every instrument. The configuration selector shows the combinations available to order.
Pump Sampling and On-Instrument Controls
The pump provides up to 1 L/min flow with ten adjustment settings. The LCD dot-matrix display shows the gas type, concentration, unit, battery level and time. English and Chinese interfaces are available, with ppm and mg/m³ concentration displays. 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 different alert outputs, including an 85 dB sound alarm and blue low-alarm/red high-alarm indicators. Use the supplied instructions and the measurement procedure for setup and operation.

Recording Options and Supplied Instrument
Data logging and PC export are optional and are not included in these High Precision base options. If measurement records are required, ask about the recording configuration before ordering. Optional sampling filters, drying accessories and high-temperature probes are separate choices; their appearance in a product gallery does not establish that they are included with every option.
The instrument weighs 300 g and has a rechargeable lithium-polymer battery. Gallery images illustrate the shared instrument housing, including views with a carrying case. An image showing several views of the detector does not represent a multi-detector order. For use, follow the instructions supplied with the selected NH3 instrument.

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.
