Myron L 727II Analog ORP Monitor and Controller
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/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 standard solutions. 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 reading. Bright green/red LED's 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 at 6" x 4.8", they are suitable for panel, bench or surface mounting.
