Teledyne B71875 InstaTrace Oxygen Sensor
Overview
The Teledyne B71875 InstaTrace is a Micro-fuel Cell (MFC) electrochemical oxygen sensor engineered for general-purpose trace oxygen analysis in inert gas and hydrocarbon streams. Teledyne’s patented InstaTrace construction eliminates the single greatest inconvenience of conventional electrochemical trace oxygen sensors — the multi-hour wait for the cell to stabilize after installation — reducing recovery time to low ppm levels from several hours down to as little as 30 minutes.
As the official authorized partner and exclusive regional representative for Teledyne in Oman and the GCC, Seven Star LLC proudly supplies the B71875 InstaTrace oxygen sensor to petrochemical plants, gas processing facilities, and industrial laboratories across the Sultanate. Every sensor shipped from our Muscat-based inventory is genuine Teledyne factory stock, fully warranted, and backed by regional application support for trace oxygen analyzer retrofits and cell replacement programs.
Operating Principle
The B71875 uses Teledyne’s Micro-fuel Cell technology, an electrochemical transducer highly specific to oxygen that generates a current proportional to the partial pressure of oxygen diffusing across its sensing membrane. Unlike zirconia or paramagnetic trace oxygen methods, the MFC sensor requires no external heating element, no reference or zero gas for calibration, and consumes its internal electrolyte gradually and predictably over a defined service life, giving operators a simple, drop-in replacement cycle without recalibration infrastructure.
The InstaTrace innovation specifically addresses the recovery period that occurs whenever a new sensor is installed and briefly exposed to ambient air during the swap. Conventional MFC cells can take several hours to recover to stable low-ppm output after such exposure; the B71875’s patented construction cuts this recovery period to roughly 30 minutes or less, meaning an analyzer can be returned to reliable trace-level service almost immediately after a cell change — a critical advantage in continuous process monitoring where extended analyzer downtime is not acceptable.
Engineering Design of the Teledyne B71875
The B71875 is supplied as a complete final assembly (standard configuration) designed to install directly into the cell block of Teledyne’s trace oxygen analyzer platforms, including the 3000T Series, 316 Series, 311 Series, and 3160 Series instruments via the appropriate retrofit cell holder kit. The sensor’s delicate Teflon sensing membrane sits beneath a protective screen, and installation requires only that the cell be placed screen-side down onto the holder, aligned with the block’s locating pin, and clamped into position to puncture the factory protective seal and form a gas-tight fit.
Because the sensing surface is fully sealed until the moment of installation, and the double-bagged storage packaging protects the cell from premature air exposure, the B71875 maintains long shelf life prior to use while still delivering the InstaTrace rapid-recovery benefit once installed. The sensor requires no maintenance beyond eventual end-of-life replacement, is unaffected by variations in sample flow rate, shock, vibration, or mounting position, and supports calibration intervals of two to four weeks or longer under stable process conditions.
Key Features
The Teledyne B71875 InstaTrace oxygen sensor delivers fast, maintenance-free trace oxygen measurement for demanding process analyzer applications:
- Reaches stable low-ppm oxygen readings within approximately 30 minutes of installation.
- Requires no external zero gas, reference gas, or heating element for calibration.
- Provides completely maintenance-free operation throughout the sensor’s service life.
- Remains unaffected by sample flow rate variation, shock, vibration, or mounting orientation.
- Supports calibration intervals of two to four weeks or longer under stable conditions.
- Retrofits directly into Teledyne 3000T, 316, 311, and 3160 Series trace oxygen analyzers.
- Ships in double-bagged storage packaging to preserve shelf life prior to installation.
- Carries a standard 6-month sensor warranty from date of installation.
Industrial Applications
The B71875 is widely used for trace oxygen monitoring in inert gas blanketing systems, hydrocarbon purity verification, nitrogen purge quality control, and specialty gas analysis across petrochemical plants, refineries, and industrial gas facilities. Its rapid InstaTrace recovery makes it especially valuable in continuous process analyzers where extended downtime during routine cell replacement would otherwise disrupt safety-critical inert gas monitoring or product purity verification.
As the officially authorized partner for Teledyne in Oman and the GCC, Seven Star LLC distributes the B71875 InstaTrace sensor to petrochemical operators, gas processing facilities, and analytical laboratories throughout Muscat, the Sohar and Salalah economic zones, and the wider Sultanate of Oman. Our authorized status ensures every sensor is genuine Teledyne factory stock compatible with your installed analyzer platform.
