The BH-90A ethylene detector offers separate C2H4 configurations in ppm and %LEL. Select the required measurement unit together with the range: the 0-100% LEL option is a different order configuration from the three ppm options.
Choose the Configuration for Your Measurement
- ppm options: Current labels specify 0-50, 0-500 and 0-1000 ppm, each with a 1 ppm label.
- %LEL option: The 0-100% LEL version is separately selectable.
- Gas identity: Ethylene (C2H4) and ethylene oxide (C2H4O) are separate gases and separate product options.

Questions Before Ordering
Can one order cover all four ranges?
The catalog lists four separate variants. Select one configuration; it does not establish that the delivered unit switches among all four.
Is the C2H4O option on another product the same as C2H4?
No. Keep the full gas identity in the order requirement. Do not choose an ethylene oxide configuration for an ethylene measurement task.

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.
