Myron L® Company’s new 900 Series Multi-Parameter Monitor / Controllers combine Accuracy, Reliability, Simplicity, and Flexibility. The user intuitive GUI (Graphical User Interface) allows easy and complete programmability of the instrument all from the LCD touch screen. These highly accurate instruments have the ability for simultaneous monitoring and controlling of multiple inputs/outputs.

Accuracy – Reliability – Simplicity…
Since 1957 the Myron L® Company has designed and manufactured accurate, reliable and simple to use instruments for a wide variety of applications. Tens of thousands of professionals around the world rely on the performance of our instruments every day. Some of our instruments have been in continuous use for over 50 years. We are proud of the trust our handheld instruments and monitor/controllers have earned.

…Flexibility
Whenever the quality of your water is a critical, make-or-break characteristic that determines your success or failure, the 900 Series Multi-Parameter Monitor/Controller is designed to be exactly what is needed whether water is your end product, an ingredient, or a secondary but vital process component. The design includes a variety of inputs, measurement types, and several different types of control and data outputs, all of which can be combined and configured to operate in the most complex water quality applications. 

Multi-Parameter Inputs
Because no two applications are exactly the same, the 900 Series’ large suite of signal inputs can be configured for a variety of measurement types. Need to interact with a remote sensor? The 900 Series includes a 4-20 mA current loop (two-wire transmitter) input and a DC mV input. Each allows you to select the units and range of measurement for display.

Adaptable Outputs
The 900 Series’ outputs also provide flexibility. Standard outputs include: 0-10 VDC recorder output and a single remote alarm and relay. Alarm status is clearly displayed with attention getting alerts. Need to control several water tanks interactively based on conditional criteria? An optional Control Module adds 2 relays, 1 alarm, a 4-20 mA output, and an RS-485 ASCII Serial Communications Output.

21st Century Interface
The 900 Series’ interface combines all of the qualities you would expect from a 21st Century instrument. Its intuitive Graphical User Interface (GUI) is easy to navigate and super simple to use. Its large, brightly colored, touch-screen display is crisp and easy to read even if you are standing off to the side or across the room. 

Quick and Easy Installation
Installation of the 900 Series is simple. Each connection uses pluggable terminal blocks. Once their mating connectors are wired-up, just plug each connector into the appropriate terminal blocks, supply power to the instrument, and begin programming.  The first time the 900 Series is powered up it leads the user through an Initial Setup process that focuses on the basic arrangement of the instruments display, assigns inputs and configures outputs. Need to precisely define the cell constant of your conductivity sensors? You can do that. Cable length of your sensors an issue? The input setup can account for it.

Flexible Display Formats
Need to display information of multiple types and from multiple sources at the same time?

The 900 Series can be configured to display information from up to four different inputs simultaneously, each displaying a different measurement type.
