729II digital pH/ORP Monitor 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. Specifications , Dimensions: 152x122x96mm (HxWxD), Range: 0-14pH, Feefo Reviews
