It features multiple input channels compatible with pre-amplified pH/ORP sensors and 4-20 mA devices, offering unmatched precision and flexibility. With integrated outputs, alarms, RS-485 communication, and programmable logic, the 900 Series empowers users to monitor, control, and log key water quality parameters across a wide range of applications. It also supports advanced temperature compensation algorithms tailored for different water chemistries.

Features

1. Pre-Amplified pH/ORP Input Compatibility

   • Designed for use with Myron L® pre-amplified sensors for greater accuracy and longer distance applications. Includes integrated 1000Ω RTD for precise temperature measurement.

2. Flexible 4-20 mA Input

   • Connects easily to most industrial sensors or transmitters. Fully scalable with user-selectable units for custom applications.

3. Versatile Output Options

   • Includes 4-20 mA/0-20 mA isolated analog output and 0-10V recorder output (model 900M-3C), both configurable for loop or self-powered operation.

4. Advanced Alarm & Relay Controls

   • Programmable relays/alarms can be set for high, low, in-range, or out-of-range triggers for any input or derived values.

5. Digital Communication & Data Logging

   • RS-485 output (model 900M-3C) streams ASCII data for seamless integration with control systems.

6. Built-in Temperature Compensation Models

   • Offers compensation for KCl, NaCl, and proprietary 442 Natural Water™. Also includes a customizable user mode for precise conductivity-to-TDS conversions and tempco settings.
