Model 3100

Compact Series
Remote Sensor Module with ZR100 Sensor

The Neutronics Model 3100 is a compact analyzer that features the Neutronics rapid response zirconia oxide sensor and a measurement range of 0.1 ppm to 100% oxygen.  With its extremely fast response time and high accuracy, the Model 3100 delivers reliable performance for a wide variety of oxygen gas measurement and critical process control applications.

The robust design of the Neutronics zirconium oxide sensor gives this analzyer the ability to rapidly measure oxygen through large step changes in concentration and accurately measure ppm concentrations of oxygen within seconds after exposure to air.
