Model 4100

Compact Series
Remote Sensor Module with ZR100 Sensor

The Neutronics Model 4100 is a compact analyzer for trace to percent oxygen gas measurement and process control applications.  With a measurement range of ppb to 100% oxygen, this analyzer features a remote sensor module with the Neutronics rapid response zirconium oxide sensor.  With extremely high accuracy, rapid response, and a long expected service life, this analyzer is a low-maintenance solution that delivers reliable performance for critical applications that require oxygen contaminant monitoring in the ppb range.
