Sensor and Transmitter (General) Features |
- PEEK housing and cord grip - PEEK is a high-end thermoplastic renowned for its chemical resistance and mechanical strength. The cord grip is a significant feature because it helps to protect the sensor’s internal components.
- Many competitors use a simple rubber or polyethylene jacket on the back of the sensor, or simply leave the back end of the sensor exposed, making the sensor more susceptible to failure
- Pt1000 RTD - The temperature element used in Quantum sensors is highly accurate and provides a highly linear output. This is one of the best available temperature compensation devices
- Integral Preamplifier - In all parameters except conductivity, the sensor contains a preamplifier that enables a maximum sensor-to-transmitter distance of up to 1000 feet for D.O., and 3000 feet for pH and ORP
- Dual O-ring seals - all seals use 2 o-rings made of 2 different materials (Viton, EDPM). This adds to the chemical resistance of the sensor
- Transmitter (General)
- Microprocessor-based, loop-powered - output signal is 4-20 mA
- Large, high contrast display - custom display includes 2 lines of data; display messages are in clear language (no “Error Codes” to look up in a manual)
- Security Lock - Prevents unauthorized tampering with settings. All settings can be viewed while locked, but they cannot be changed
- Universal mounting bracket - transmitter can be mounted to a wall, DIN rail, panel, pipe, or directly on the back of the sensor
- Fully isolated - protected from surge and brownout.

System Feautres, Ph and ORP |
- High Volume Saltbridge - maximizes the service life of the sensor by minimizing rate of contamination of the reference solution. The saltbridge is replaceable
- A second pH reference electrode is reference element of the sensor. This is what makes the Quantum sensor better than the “combination-style” sensors on the market: the reference element is protected from chemical attack
- Electrode breakage diagnostic
- Transmitters can be used with other “combination-style” sensors. This is the one area in which there is compatibility with competitive sensors.
- If the application is such that the customer requires a cheap disposable sensor, etc., our pH and ORP transmitters will function with those as well

D.O. System Features |
- 3-electrode Polarographic sensor - best technology for long-term measurement stability
- Replaceable electrolyte cartridge - cartridge contains electrodes, electrolyte and membrane. Cumbersome membrane replacement is unnecessary
- Membrane tear diagnostic
- Conductivity System
- 4-electrode sensor type - greater accuracy than 2-electrode type, also enables precise monitoring even as electrodes are coated with chemical deposits
- Titanium electrodes - greater chemical resistance
- Electrode coating/fouling diagnostic
- Selectable manual or automatic ranging
