Measure nitric oxide with the MH2000-NO flue-gas-specific detector, available in four ranges from 0-500 to 0-5000 ppm. This portable, single-gas instrument uses an electrochemical sensor and an internal sampling pump. Its High Performance sensor configuration is intended for flue-gas NO measurement and includes interference resistance for that application.
Flue-Gas Configuration and Range Selection
Choose 0-500, 0-1000, 0-2000 or 0-5000 ppm when ordering. One detector is supplied with the selected measuring span. The interference-resistant configuration does not establish complete immunity to every interfering gas, and the instrument measures NO rather than total nitrogen oxides.
This product uses the flue-gas-specific sensor configuration. The separate High Performance NO options designated unsuitable for flue-gas environments serve a different application. Select the sensor configuration first, then the measuring span required by the procedure.
Sampling Arrangement
The instrument has up to 1 L/min pump flow with ten adjustment settings. Probe temperature capability, filters and drying accessories are separate sampling-package choices. The detector's operating temperature is -20°C to 50°C; this value is not a rated temperature for a probe in a hot flue. Choose the sampling arrangement for the application before ordering.
The housing weighs 300 g and measures 205 x 75 x 32 mm. A rechargeable lithium-polymer battery powers the instrument. Data logging and USB export are optional and excluded from this base 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.
