Myron L O74DR ORP Sensor for 750II Monitor/Controller 3/4" MNPT Double Junction for Environmental Applications (Potassium Nitrate Gel) w/ 10' Cable

All Myron L Company Oxidation Reduction Potential or ORP (REDOX) sensors are combination ORP/reference. 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 - completely 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.

Myron L preamp is so simple and low cost that we build it right into the sensor, thus allowing for a truly sealed sensor system - no O-rings to become damaged and leak, no BNC connectors to corrode and cause unreliable readings. It is actually no more expensive than the BNC connectors and coax cable it replaces.

Sensor bodies are made of Ryton Polyphenylene Sulfide (PPS) to withstand the demanding requirements of most applications. 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. Overall length is 165 mm/6.5 in. Standard cable length is 3 meters/ 10 ft.

For in-line use, simply install sensor into female threaded fitting or tee. For submersion use, simply install into user supplied pipe coupling and extension pipe.

Special Purpose Double Junction

Low Cost In-line/Submersion pH and ORP Sensors

The Double Junction "D" reference sensor is used in more demanding applications where "poisoning" of the reference is a possibility or a concern. It uses Potassium Nitrate (KNO₃) gel where the reference meets the solution. This sensor is an ideal, cost effective alternative for demanding environmental applications not requiring the added advantages of the Heavy Duty Flat Tip sensor listed below. Response time, generally 95% in one second. When in doubt it is best to select a Double Junction sensor. Twelve (12) month shelf life. This sensor is the ideal, most cost effective Double Junction sensor on the market.

Advantages:

• Built-in isolated preamp guarantees accurate, trouble free operation.
• Temperature Sensor built-in for automatic Temperature Compensation (may be disabled as required).
• All sensors are double ended MNPT for simple in-line or submersion applications.
• All sensors are ORP/ reference.
• CPVC bodies assure compatibility in most applications.
• All sensors are completely encapsulated and sealed.
• Sensor cable may be extended simply, without problems.
• All ORP sensors have an extended tip Platinum electrode except "F" models.
