 The
unique circuitry of the 750 Series II Conductivity Monitor/controllers
guarantee 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. Uncompensated
models available to conform with USP 24.
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/below
setpoint readings.
All 750 Series II models feature an IP64/NEMA
3X splash and corrosion-proof rated enclosure while being
a compact size at 6x4.8 inches (15.2x122mm). They are
suitable for panel, bench or surface mounting.
Additional options include a 3 Sensor input,
a 3 Range switch (both installed separately from the monitor/controller),
and a RA™ - Remote Alarm. Custom and OEM Models
available. Contact us with your requirements.
