The Myron O74LCR is an ORP (Oxidation Reduction Potential) low conductivity sensor with a double-ended 3/4-inch MNPT body and standard 10-foot (3-meter) cable.

These sensors are designed to operate exclusively with the Myron L Company 720 Series II ORP Monitor/controllers. Each sensor has a uniquely designed, built-in isolated preamplifier that guarantees accurate and reliable measurements, eliminating ground loops and noise issues. The preamp allows for longer distances between the sensor and monitor/controller without the loss of accuracy or reliability due to cable capacitance, resistance, or noise.

All Myron L sensors are completely encapsulated and sealed to keep out moisture and to assure long life under demanding conditions. Just install and use. For in-line use, simply install the sensor into a female threaded fitting or tee. For submersion use, simply install into user-supplied pipe coupling and extension pipe.

The low conductivity (LC) sensor is recommended when the pH or ORP of low conductivity (low ionic strength) solutions must be measured. This sensor utilizes a porous polyethylene Double Junction with a low molar (0.1) KCI gel in the reference meeting the solution. This low molar reference more closely matches the low ionic strength of the solution, which allows more stable readings and cuts down on the contamination of the solution being measured. The LC sensor is recommended for use in RO/DI applications with solutions less than 100 µM/ µS/ppm. This sensor is made for special, low conductivity applications. It has a twelve-month shelf life.
