Oxygen Detecor

Part number: ESCM-37 and ESCM-38

ESCM-37 Oxygen DetectorAir Quality Sensorsc provides an oxygen sensor and transmitter for HVAC controllers or BMS units.

The ESCM-37 is a long life 0-25% or ESCM-38 0-95% oxygen level transmitter that provides multiple analog linear outputs of O2 concentrations. It is designed to be rugged, maintenance-free and can be calibrated in normal air of any known oxygen concentration.

Outputs include voltage and 4..20mA. Multiple units may be daisy chained for via RS485. The base address for each sensor is selected via on board jumper.
