pH/ORP Monitors/Controllers 720 Series II
From Myron L Company
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 Myron L 720 Series II pH Monitor/Controller without the loss of accuracy or reliability.
All Myron L 720 Series II 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.
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.
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.
