R-4OX Industrial Oxygen Sensor

CCR R-4OX Industrial Oxygen Sensor

Select an oxygen sensing element for a compatible fixed gas detector.

Verify the mechanical fit
Check the 32 mm form factor and mounting details against the host instrument.
Match the electrical signal
Review output and load requirements before integration.
Plan service
Confirm calibration and replacement intervals for your operating environment.

Compatibility and service life depend on the host instrument and supplied sensor revision.

Overview

The CCR R-4OX is a 32 mm oxygen sensing component intended for compatible fixed gas detectors. Match the mounting dimensions, output signal and load to the host instrument before ordering.

Confirm the required oxygen range, calibration procedure and service conditions for the supplied sensor revision.

Maximum s/c Current (10 to 100% O2)	0.5 A

Toxic gases at TLV levels will have no cross-sensitivity effect on CCR-Scientific oxygen sensors. At very high levels (i.e. percent levels), highly oxidising gases (e.g. ozone, chlorine) will interfere to the extent of their oxygen equivalent, but most other commonly occurring gases will have no effect.

Acid Gases

IMPORTANT NOTE: Acid gases such as CO2 and SO2 will be absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO2. CCR Scientific oxygen sensors are not suitable for continuous operation in concentrations of CO2 above 25%.
