4-20 mA pH transmitter PHT300

4 - 20 mA Output TWO On/Off Outputs 4-Digit Display (2 Decimals) Fast Response Electrode Automatic Temperature Compensation Flow Through & Submersible Applications INTRODUCTION Indumart PHT300 SeriesLoop-powered pH Analyzer / Controller / Transmitter is a cost effective solution for accurate measurements of pH in industrial and municipal applications and control of the process. Designed for a wide variety of applications, the PHT300Series features automatic temperature compensation, two control contacts and a 4-20 mAoutput for recording or control. The microprocessor-based circuitry equipped with digital filters provides stable readings with very good accuracy. The instrument consists of two parts: 1) pH probe, 2)transmitter/indicator.TheindustrialcombinationpHglasselectrodeusestheconventional technique, employing a process electrode and a reference electrode in KCl solution. The convertible design of these probes allows them to be used both in flowthrough and submersible applications. The pH value is indicated on a 4-digit display and configuration parameters are programmed via a two-keyhiddenkeyboard.Thecontacts'parameterssuchassetpoints,hysteresis,direction of the alarms and their time delay can be programmed by the user. The transmitter section of the PHT300is suitable for wall mounting, and if required, it may be ordered with DIN rail clamp for rail mounting.
