Features

Process Control Relay

The Standard 903 has one relay set point standard for process control that can be set to trip anywhere within its set point range. Set point activation status is shown with one of three LED indicators. Power and high voltage status are also indicated.

High Voltage Activation

The high voltage activation feature is a convenient way for you to shut off power to the 903 locally without shutting down your entire system. Deactivating the high voltage at pressures above 10-2 Torr reduces the effects of contamination in the sensor.
