Non Glass ISFET inline process pH probes

Non glass Isfet probes for online applications The online series ISFET probes are specially designed for building into online pH monitoring systems. The ISFET probe is inherently robust and offers the advantages of long life, easy maintenance and safety (no glass) to process applications. The probe is constructed of PEI and the electronics are safely embedded in the probe. Power is supplied from an external 5V power supply. You can choose either a 0-5000 mV output range making the probe compatible with data logging and PLC controllers or conversion of the ISFET signal to simulate the characteristics of a glass probe so that it can be used with conventional pH monitoring electronics. The probe can operate up to 70C and 3 bars of static pressure.
	In line bayonette pipe fitting for the probe	The ISFET cable adaptor box supplies the 5 V power and provides the pH signal via a BNC or other connector to match your instrumentation
