Choose an electrochemical ethylene oxide detector by the concentration span required for your measurement. The MH2000-EO uses internal pump sampling and is available in six Standard versions, from 0-10 ppm through 0-1000 ppm. Ethylene oxide may also be identified as EO or EtO.
Six Standard Range Options
The 0-10, 0-50 and 0-100 ppm versions cover lower maximum concentrations. For a wider measuring interval, select 0-200, 0-500 or 0-1000 ppm. Every option starts at zero and measures the same gas using the electrochemical configuration.
The range selected when ordering is the measuring span of that instrument. A six-option menu does not mean that one detector switches between all six spans. Match the chosen upper limit to the expected concentration and the requirements of the measurement procedure.

Readings and Instrument Controls
The LCD presents the concentration, gas identification, selected unit, battery level and time together. Concentration units can be changed between ppm and mg/m³. Sound, light and vibration provide alarm outputs, and the alarm setpoints are adjustable.
Self-calibration and zero calibration are available for instrument setup, along with a factory reset. Follow the supplied instructions for the selected measuring version when using these controls.
Sampling and Order Details
The operating limits in the table apply to the instrument. Select the sampling arrangement to keep the measurement within those temperature and non-condensing humidity conditions. If stored readings or PC downloads are required, specify the recording and export arrangement when ordering. Filters, drying accessories and probes are separate package choices.
This link covers the Standard electrochemical configuration. The PID PPM configuration is offered as a separate product. Gallery photographs show the shared pump-detector housing; displayed readings are illustrative, and the carrying-case view does not represent a two-instrument package.

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.
