Myron L 750 Series II Resistivity Monitor
The unique circuitry of our 750 Series II Resistivity Monitor guarantees accurate and reliable measurements. Drift-free performance is assured by "field proven" electronics, including automatic DC offset compensation and highly accurate drive voltage.
Since Temperature Compensation is at the heart of accurate water measurement, all Myron L Monitor/controllers feature a highly refined and precise TC circuit. This feature perfectly matches the water temperature coefficient as it changes. All models are corrected to 25°C. The TC may be disabled to conform with USP requirements. Built-in electronic calibration allows for fast quality checks. A push-to-test button makes setpoint 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 readings above or below setpoint. All 750 Series II models feature an IP65/NEMA 4X water-resistant and corrosionproof rated enclosure. Compact in size at 152 x 122 mm/6 x 4.8 in., they are suitable for panel, bench or surface mounting. Additional options include a 3 Sensor Input Switch and/or a 3 Range Switchand a Remote Alarm model RA.

Wetted materials of construction are 316 stainless steel and Teflon®*, with double O-ring seals at all points. The first EPR O-ring bears the brunt of process interface, allowing the second O-ring to maintain reliable sealing, free from chemical attack. An integral temperature element allows automatic compensation for maximum accuracy. Leads are 10 ft./3 meters standard.
Process connections are made via a bored through swage 3/4 NPT fitting as standard. This fitting may be installed into a line or tank, or may be reversed and connected to a standpipe for use in a submersion configuration.
