The BH-90A hydrogen detector offers three H2 concentration-span options: 0-1000, 0-2000 and 0-5000 ppm, each labeled 1 ppm. Choose the range needed for the H2 measurement. A gas-specific ppm configuration is a different selection from a general combustible-gas %LEL product.
Choose the Configuration for Your Measurement
- Gas: Hydrogen (H2), not hydrogen sulfide (H2S).
- Range choice: Three separate variants with the current 1000, 2000 and 5000 upper-span labels.
- Order reference: Retain the selected SKU when comparing package, sampling and alarm details.

Questions Before Ordering
Will this also measure H2S?
This is the H2 configuration. Hydrogen sulfide is a separate gas and has dedicated product pages and configurations.
Can I interpret the ppm range as %LEL?
Use the unit specified for the selected instrument and the required procedure. This page does not convert its ppm variant labels into an interchangeable %LEL specification.

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.
