The MH2000-SF6 measures sulfur hexafluoride concentration with an infrared sensor and internal pump sampling. Choose a 0-1000 ppm or 0-2000 ppm version for the measuring span required by the sample and procedure. This portable High Precision configuration is a single-gas SF6 detector, with interference resistance for its selected sensor arrangement.
Choose the SF6 Measuring Span
The 0-1000 ppm version has a lower maximum measuring span, while the 0-2000 ppm option covers a broader concentration interval. Both have 1 ppm resolution. One instrument is supplied with the range selected when ordering; it does not automatically switch between the two order versions.
The instrument measures SF6 concentration within that span. The configuration does not establish gas-purity analysis, dew-point measurement or a quantified leak-rate output. Interference resistance identifies the sensor configuration and does not mean complete immunity to every interfering substance.

Sampling, Display and Instrument Setup
The internal pump draws the sample at up to 1 L/min. An LCD dot-matrix display shows concentration alongside the gas type, unit, battery level and time. The operating temperature is -20°C to 50°C, with non-condensing humidity up to 95% RH. Match the sampling arrangement to these instrument operating conditions.
Sound, light and vibration provide the alarm outputs, with adjustable setpoints. Self-calibration, zero calibration and factory reset are available for setup. Use these controls according to the supplied instructions for the selected SF6 version and the measurement procedure.
Recording and Package Requests
If the procedure requires stored readings or PC downloads, specify the recording/export arrangement when ordering. Sampling filters, drying accessories and probes are separate package choices for the intended measurement arrangement.
The 300 g housing uses a rechargeable lithium-polymer battery. Gallery photographs illustrate the shared pump-detector housing and controls. Screen readings are illustrative; a case view does not represent two supplied instruments, and a connected cable does not establish included PC export.

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.
