A cost-effective solution for precision water quality control

May 07 2024

Myron L® Company’s 900 Series multi-parameter water quality monitor/controller is easy to install, easy to use, and does the job of seven separate instruments single-handedly.

Precisely monitor and control an array of critical water and wastewater parameters with the legendary accuracy and reliability the Myron L Company has come to be known for. The 900 Series Monitor/Controller features a simple-to-use LCD touchscreen Graphical User Interface along with pluggable terminal blocks for quick and easy equipment installation and configuration.

Get a comprehensive real-time picture of solution status with continuous readings from up to seven different inputs: 2 Conductivity/Resistivity/TDS/Salinity; 1 pre-amplified pH/ORP; 1 BNC pH/ORP; 1 flexible 0-20/4-20 mA; 1 RTD Temperature; and 1 Flow/Pulse. % Rejection is also available as a derived value. For maximum accuracy, the Conductivity and TDS functions allow you to select the solution type used to model the solution under test: KCl, NaCl, or Myron L’s own 442 Natural Water™ Standard. Or program a 'User' solution mode when solution constituents and behaviour are known. Temperature compensation is automatic to 25°C but can be disabled by the user as required. The pH/ORP input channel works with Myron L pre-amplified pH and ORP sensors which contain precision circuitry that increases accuracy and permits application of the sensors over greater distances. The 0-20/4-20 mA input allows user-defined 0 to full scale values and units of measure for a wide variety of sensor types. Electronic or wet calibrations are easy to perform.

Automatically trigger control equipment and audible signals and continuously report and record solution data with flexible outputs. The 900 features up to 3 relays; 2 remote alarms; 1 0-20/4-20 mA signal; 1 0-5/0-10 VDC signal; and 1 RS-485 ASCII serial signal. Relays output to any user-supplied control equipment requiring up to 250V each and can trigger on any input parameter. The 0-20/4-20 mA output can transmit a signal for any input parameter. 0-5/0-10 VDC can be scaled to optimise resolution and can output to a recorder, PLC, SCADA system, etc. 0-1 VDC is possible with optional resistor. 

Myron L also backs these instruments up with expert dedicated technical support that assures installation and operation success.
