Frequently Asked Questions

What is the THERMO SCIENTIFIC OZ31B sensor used for?

The THERMO SCIENTIFIC OZ31B is a membrane-junction sensor designed for measuring dissolved oxygen (DO) or biochemical oxygen demand (BOD) in liquids. It is commonly used in water quality monitoring, wastewater treatment, and environmental testing applications where accurate oxygen measurement is critical.

What are the specifications of the THERMO SCIENTIFIC OZ31B sensor?

The THERMO SCIENTIFIC OZ31B sensor has a membrane junction, a CPVC material construction, and a 1 3/8 in overall diameter. It is classified as a DO/BOD sensor for liquids, with manufacturer part number OZ31B. These specs ensure compatibility with standard mounting and liquid immersion setups.

Where to buy the THERMO SCIENTIFIC OZ31B sensor worldwide?

You can source the THERMO SCIENTIFIC OZ31B sensor worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine components for water quality applications.

How to install the THERMO SCIENTIFIC OZ31B membrane sensor?

Install the OZ31B sensor by immersing it in the liquid sample, ensuring the membrane junction is fully submerged. Connect the sensor to a compatible DO/BOD meter using the appropriate cable. Follow generic best practices: avoid air bubbles on the membrane, calibrate per meter instructions, and clean the CPVC body with mild detergent.
