Advanced SEM Sensor Technology

SEM Sensors represent a new generation of electrochemical sensor technology designed to provide compliance-level emissions data. Advanced materials of construction and configurations have improved operational performance in a number of important areas that have historically limited the applicability of electrochemical sensors to provide quality assured, compliance-level emissions data.

Precision Control Modules

Unlike any other sensor, SEM Senors are equipped with a Precision Control Module (PCM), that combine sensitivity range and interference rejection filter.

The PCMs are available in two versions:

• Model 700 & 3000 - PCM and Sensor are integerated as one module.
• Model 3000E - PCM is detachable from the sensor. The Enerac's analytical range can be extended by using different PCMs. In addition, the sensor does not have to be replaced when the interference rejection filter is exhausted.

These interchangeable Precision Control Modules provide superior sensor selectivity, performance, and flexibility.

SEM Advantages:

• Improved long-term performance
• Enhanced sensor selectivity
• Negligible cross sensitivity
• Increased operating range & accuracy
• Reduced drift
