A cost-effective solution for precision water quality control

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.

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 behavior 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: 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.  0-1 VDC is possible with optional resistor. Signals can output to a recorder, PLC, SCADA system, etc.

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