Stainless Steel O2 Probes with 1000 micron single glass fiber optic

SELECT OPTION:

Stainless steel oxygen probes designed for feed throughs in atmospheric and high pressure chambers. All probes include factory calibration settings.

 

These probes are designed to have replaceable caps for periodic replacement.  The probes can be configured with or without a thermister.  In applications with changing temperatures a thermister configuration is recommended.  The replaceable caps are ideal in applications where the probe (fiber-thermister) are part of the sensing fixture (e.g., a Swagelock assembly).  Thereby this makes periodic maintenance simple by replacing only the cap.  The price for the caps includes a factory calibration which improves accuracy and replacement time.

Zero drift O2/DO sensor, 1000/2000 micron polymer fiber, 7" long, SS, 55 bar pressure rating. Thermistor length is 5'. Longer length thermistor of 10', 20', and 30' are available. Price include factory calibration.

High performance oxygen sensor. Dip probes with embedded thermistor with OD and (W, BA, BMS, no) protective coating. 

W -- white acrylic overcoat
BA -- black acrylic overcoat
BMS -- black Medical Silicone overcoat

 

Hydrocarbon resistant oxygen sensor replaceable screw caps with (0.25", 0.375") OD and (W, BA, BMS, no) protective coating. There are two types of cap coatings. 

1) The HIPOXY (formerly AP) series designed for zero long term drift with applications:

Environmental monitoring
Process control
In line monitoring in beverage industry
Waste water treatment
Long-term measurement in soil

2) The HYROXY (formerly HCR) series for Hydrocarbon Resistant Oxygen applications:

Oil industry: refineries, fuel processing
Chemical industry involving explosive hydrocarbons and flammable solvents
Aviation industry: OBIGS, OBOGS, online real-time fuel tank monitoring
