The
advanced "isolated" circuitry of the 720 Series
II pH/ORP Monitor/controllers guarantees accurate and reliable
measurements completely eliminating ground-loop and noise
issues.
The unique sensor preamp allows for longer distances
between the sensor and the Monitor/controller without the
loss of accuracy or reliability.
All Myron L pH Monitor/controllers feature a
highly refined and precise Temperature Compensation circuit.
This feature perfectly matches the NERNST equation correcting
the displayed reading to 25ºC. The TC may be disabled
to conform with USP 24.
Built-in electronic calibration allows for fast
quality checks without buffers.
(Note: for maximum system accuracy buffers are recommended).
A push-to-test button makes set point 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 LED's indicate above/below
set point readings.
All 720 Series II models feature a IPA64/NEMA
3 splash & corrosion-proof rated enclosure. Compact
in size, 6 x 4.8 inches (152 x 122mm), the 720 Series II models
are suitable for panel, bench or surface mounting.
Accessories include a Remote Alarm - RA™.
Custom and OEM Models available.
pH/ORP
Sensors
These highly accurate sensors utilize a preamplifier to ensure
stability over longer distances, and to eliminate potential
noise problems thereby ensuring accurate repeatable readings.
In addition, these reliable sensors feature
an integral temperature sensor to ensure accurate and rapid
automatic temperature compensation.
Several choices of sensors are available, in
1/2 MNPT or 3/4 MNPT, depending on the demands
of the application. The basic pH sensor utilizes the standard
round glass electrode with a single reference junction. The
basic ORP sensor utilizes a Platinum electrode with a single
reference junction. See 720II Sensor Selection Guide for additional
information.
NOTE: Heavy Duty F model sensors
may be installed in ANY direction including inverted.
