Myron L

® Company, of Carlsbad, Calif., offers 720 Series II pH/ORP Monitor/Controllers with isolated circuitry for accurate, reliable measurements without ground-loop and noise. A unique sensor preamp allows for longer distances between the sensor and the monitor/controller without loss of accuracy or reliability.

All Myro L monitor/controllers feature a precise temperature compensation circuit. 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 and red LEDs indicate above or below set-point readings.

All 720 Series II models feature an IP65/NEMA 4X water-resistant and corrosion-proof rated enclosure. Compact in size, the 720 Series II models are suitable for panel, bench or surface mounting. Additional options include Remote Alarm™ model RA.

Several choices of sensors are available, in ½-inch MNPT or ¾-inch MNPT. 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.
