Model 150-pH

Single Set with Band-type ± Alarm pH Controller with Iso 4-20mA Tx

Features

Model 150 pH Controller is panel mounted DIN size instrument with 3½ Digit LCD.
Indicates pH when attached to a pH electrode. The membrane key pad MODE SWITCH in front allows indication of normal pH.
Limits for acid/base together with additional band alarm limits for acid/base.(acid/base logic internally selectable).
In addition a Consent contact output is provided to be used in conjunction with an ORP Controller for ORP dosage.
The equipment also provides an Isolated 4-20mA output for recorder purpose.
