The Rosemount Analytical TF396 pH Sensor is a non-glass pH sensor for submersion or insertion applications. The TF396 is suitable for use at cold temperature with continued rapid response and accuracy. The calibration frequency is reduced due to increased sensor stability. Minimum sensor maintenance is required with the TUpH reference technology which ensures continued reference performance when the sensor becomes coated.

The ion-selective field effect transistor (ISFET) pH electrode provides a stable pH measurement. Its rate of response can be ten times faster than glass electrodes, enabling better process control. Its short response time and increased stability at low temperatures make it suitable for use in cold processes like brine or water for cooling. Aging effects caused by temperature fluctuations or large changes of process pH are greatly reduced, providing longer intervals between calibration and maintenance of the sensor.

Because there is no glass bulb, it can be used in many applications that restrict or prohibit pH glass electrodes due to the risk of broken glass getting into the process. It may also provide longer sensor life in processes that will break or crack pH glass bulbs. By allowing direct installation into the process, costs for laboratory analysis of sample lines are greatly reduced.
