The unique circuitry of the 750 Series II
Conductivity Monitor/controllers guarantees
accurate and reliable measurements.
Drift-free performance is assured by
“field proven” electronics, including
automatic DC offset compensation
and highly accurate drive voltage.
Since temperature compensation is at the
heart of accurate water measurement, all
Myron L Monitor/controllers feature a highly
refined and precise TC circuit. This feature
perfectly matches the water temperature
coefficient as it changes. All models
corrected to 25°C. The TC may be disabled
to conform with USP requirements.
Built-in electronic calibration allows for fast
quality checks without standard solutions.
(Note: for maximum system accuracy
standard solutions are recommended).
A push-to-test button makes setpoint
checks easy, while the internal alarm set
discourages unauthorized adjustments.
Standard on all controller models is a
heavy-duty 10 amp output relay, operating
on either increasing or decreasing
readings. Bright green/red LEDs indicate
above or below setpoint readings.
All 750 Series II models feature an IP65/
NEMA 4X water resistant and corrosionproof
rated enclosure. Compact in size at
152 x 122 mm/6 x 4.8 in., they are suitable
for panel, bench or surface mounting.
Additional options include a 3 Sensor
Input Switch and/or a 3 Range Switch
and a Remote Alarm™ model RA.
