pH and ORP Electrodes (Signet 2714-2717, 2754-2757, 2764-2767, 2774-2777, 3719 Wet-Tap Valve)

We offer a full line of pH and ORP electrodes including the unique DryLoc® and Twist-Lock designs that ensure a robust and watertight connection between the electrode and the preamplifier or sensor electronics.

Customers can choose between flat glass electrodes, which are ideal for measurement in high sediment liquids, and the bulb glass design. There is also the option of extended wet-tap electrodes (for use with the type 3719 Wet-Tap Assembly) that allow operators to retract the electrode for service without process shutdown.

Fields of Application:

* aquatic animal life support systems
* water & wastewater treatment
* neutralization systems
* surface finishing
* pool & spa control

The pH/ORP Preamplifiers enable a quick and robust connection for Twist-Lock and DryLoc® electrodes which can then wire into one of our pH/ORP instruments.

The 2760 can also be used as a simple connector for use with other manufacturers’ instruments that do not require a pre-amplified signal.

Fields of Application:

* Response time: pH < 6 seconds for 95% of change, ORP is application dependent
* Measurement range: 0 to 14 pH, ±2,000 mV
* Operating temperature: up to 110°C

pH ORP Sensor Electronics

The type 2750 is equipped with a pre-amplified signal and features two different outputs: a two-wire 4 to 20mA loop output, or a digital (S3L) output which allows longer cable lengths and is compatible with the type 8900 multi-parameter controller.

The DryLoc® connector design enables quick and robust connections with the full line of DryLoc® pH/ORP electrodes.
