M85

The M85 Oxygen Transmitter is a versatile unit that detects oxygen concentration within a specified range. This transmitter was designed with ease of use in mind, and only offers two field settings: zero and span. The M85 can be packaged for GP, C1D1, or C1D2 electrical area classifications.

The M86 is now obsolete.  It has been replaced by the M86.
