Industrial Process Control

The 6309POT pH/ORP Analyzer and Controller is an easy to use instrument that measures, analyzes, and controls pH, ORP, and temperature.

The 6309POT’s built-in temperature and automatic temperature compensation (ATC) functions may be used with an ATC-type sensor or with a 10K ohm thermistor.



The Global Water 6309POT multiparameter pH/ORP Controller measures, analyzes, and controls pH, ORP and temperature in one easy to use unit.  The pH/ORP Controller's setup and calibrations are done through a user-friendly menu that may be password protected.

Calibrations can be performed quickly and accurately with automatic buffer recognition of U.S. or European buffer sets, with the values stored in the pH/ORP Controller's nonvolatile memory.  A large backlit display on the pH/ORP Controllers provide pH, ORP, and temperature plus the current mA output and relay status.

Global Water, founded in 1990, is a manufacturer, distributor, and systems integrator of water instrumentation serving the water, wastewater, and environmental markets.

Sensidyne's four channel controller automatically recognizes SensAlert Plus transmitters and configures controller for gas name, measuring units, span, and default alarms.

Sensidyne - Four channel controller

The controller has a latched alarm reset button and discrete LED value displays plus LCD displays for gas name or type and value. Discrete 4-20 mA and RS-485 Modbus RTU outputs are standard.



The SensAlert 4-Channel Controller powers and monitors up to 4 channels of gas detection. With three alarm relays per channel plus a common fault relay, the Controller provides local or remote alarm annunciation via the optional strobe and standard 90 dB buzzer.

Sensidyne was founded in 1983 as a manufacturer and distributor of gas detection equipment. In 1995, the Gilian Instrument Company was acquired to expand the existing line of vapor and particulate personal sampling pumps.

Sensidyne - Air Monitoring systems

Sensidyne is a leading provider of gas detection systems designed to detect toxic and combustible gas levels in ambient air in a variety of industries.
