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 Advantages: In addition to the standard line of pH and ORP electrodes, we also offer differential designs which utilize the filed-proven 3-electrode technique: the pH and reference electrodes are measured against a ground electrode, ensuring a steady and stable signal. All electrodes are made of a durable Ryton® body for superior compatibility to most harsh chemicals and the ability to withstand high temperatures Range: DN20 and up Measurement range: 0 to 14 pH, ±2,000 mV Operating temperature: up to 110°C Operating pressure: up to 10.3 bar (149 psi) Materials: Ryton®, PTFE, Glass (pH) or Platinum (ORP)
