Fail Safe Alarm System

Hanna’s exclusive Fail Safe Alarm System protects against problems caused by power supply failure or signal interruption, which are typical risks in industrial environments. An alarm condition is indicated by a red LED, located directly on the front panel of the controller.

Analog Output

To enhance troubleshooting and the ability to record data while monitoring, simply attach a recording device to the instrument’s 4 to 20 mA output contacts, conveniently located on the front panel, to obtain a hard copy of the results on demand.

Differential Input

In a system with poor grounding, it is possible to have a ground current flowing through the reference junction. This can cause a rapid degradation of the electrode. The Hanna differential input reduces the likelihood of ground loops.

PC Connectivity

RS232C port allows for connection to a PC. Data transmission from the instrument to the PC is possible with the HI 92500 Windows® compatible application software offered by Hanna Instruments.

Proportional Control

Slows the pump down when the measured pH level approaches the set value, which ensures precise dosage and avoids costly waste of chemicals due to overdosage.

Automatic Temperature Compensation

A 2-wire Pt100 can be connected to provide automatic temperature compensation of measurements.
