Product Options

Overview

PH/ORP control is now supremely easy using the Alpha pH 200 limit controller, this device features 6 sub menus all controlled via a four button keypad. Set up, Calibration and password protection is all simply controlled by the user in a few simple steps.

Clear uninterrupted readings are delivered even in electronically noisy environments by using the symmetrical mode whilst the two SPDT relays with independent hysteresis produced effective high/low set points limit control with minimal relay chattering.

User friendly options of Eutechs' Alpha pH 200 are the choice of automatic or manual temperature compensation, in addition to this is the three wire system which compensates error due to cable resistance. 85 to 250 VAC. 50/60 Hz or DC variable input allows the user to set up this controller in a wide range of supply voltages and full scale 4 to 20 mA galvanically isolated current output for process control.

The Alpha pH 200 features a heightened security mode which enables the user to set two levels of password to protect against unauthorised tampering and access only to calibration and set up menus via pre set passwords.

This product is covered by a 1 year warranty.
