Resistivity Monitor / Controllers
 

The advanced circuitry of the 750 and 760 Series Resistivity Monitor / Controllers guarantees accurate and reliable measurement of ultrapure water. Drift-free performance is assured by "field proven" electronics, including automatic DC offset compensation and highly accurate drive voltage.

Resisitivity Monitor / Controllers

Since temperature compensation is at the "heart" of an accurate pure water measurement, all Myron L resistivity monitors feature a highly refined and precise dual thermistor TC circuit. Actually an analog computer, this feature perfectly matches the pure water temperature coefficient as it changes. Resistance readings are automatically compensated for the effects of temperature on both the impurity ions in water, and on the ultrapure water itself.

A push-to-test button makes set point checks easy, while the internal alarm set discourages unathorized adjustments. Bright green/red LED's indicate above/below set pint readings. Also standard on ll models is a heavy-duty 10 amp output relay.

The three 750 models (ananlog, didigtal, and "control only") are each a compact 6x5 inch size. Model 762 featues a large 4 1/2 inch meter movement and three ranges for excellent readability. Model 762 is also available with an optional built-in three-cell input capability. This option can also be ordered with the 750 Series models, but must be installed separately from monitor / controller. All models have drip / weather-proof housings which can be panel or sufrace mounted.
