723II digital pH Monitor/Controller 115/230Vac

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 Monitor/controllers feature a highly refined and precise Temperature Compensation circuit. This feature perfectly matches the NERNST equation correcting the displayed reading to 25°C.

The TC may be disabled to conform with USP requirements.
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 LEDs indicate above/below set point readings.

All 720 Series II models feature an IP65/ NEMA 4X water resistant and corrosion proof rated enclosure. Compact in size, at 152 x 122 mm/6 x 4.8 in., the 720 Series II models are suitable for panel, bench or surface mounting

Factory Fit Options include, 24VDC power supply, 4-20mA output and second alarm for the monitor controllers. A range of pH/ORP probes are availble for these meters.
