Another cost benefit is a natural zero, i.e. reading 4ma when ambient oxygen drops to zero; which may seem trivial, unless you have experience with competing sensors that don't. Calibrating the OxyBoss*100 is simple; use ambient air to set an upscale 20.7%. The cost savings?.. Well, with a natural zero, you never have to calibrate the zero point, a tedious process requiring what seems to be an interminable application of nitrogen. Safety, performance, reliability and low cost combine in the OxyBoss*100. This fine US-built product is engineered for quality, safety and performance.

Parameters: Oxygen, volume percent, 4-20mA analog transmitter

Technology: Electro-chemical

The OxyBoss*100 is an oxygen analyzer; 2-wire, stationary transmitter. It operates from 10-30 VDC, generating a 4-20mA (sinking) analog signal proportional to the O2 level (volume ratio). Unit is housed in a sturdy, dust proof fiberglass enclosure. A digital meter may be added. Space is provided to install an optional trip point relay module, with user adjustable trip points and SPDT (1A) contacts.

The OxyBoss*100 offers unusually long O2 cell life... units often in service for a year or more without requiring cell replacement. Long term stability, temperature compensation, easy calibration and tolerance for moisture and dust have given this instrument a reputation for dependability. A dust filter and calibration adapter are included. A flow through adapter is available for low pressure in-line monitoring. The unique O2 sensing cell assembly will not rust or corrode, the nemesis of competing products for wet environments.
