pH-Digital Monitor/Controller, SC, 4A, PA, PC Options
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 25°C. The TC may be disabled to con form 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.
