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.
