Advanced ISM for process control
ISM's advanced sensor diagnostics adjust in real time to changes in processing conditions. The HART communication protocol provides for the seamless integration of sensor diagnostics into process control systems.
Reduce Time in Hazardous Areas
ISM sensors with Plug and Measure technology can be pre-calibrated in a workshop with iSense software and stored for later use. When connected to the transmitter, calibration data are automatically uploaded and the system is instantly ready to measure.
Multiple Analytical Parameters
This multi-parameter transmitter can be used to monitor pH, ORP, conductivity, dissolved and gas-phase oxygen, and dissolved carbon dioxide. One unified interface for a variety of applications simplifies training and use.
