WD-35807-30 Teflon-junction, CPVC-body pH Electrode (Use with pH 100, 200, 800, and 1000 controllers) by Oakton

A. In-line submersible electrodes feature a probe guard to protect sensor from damage. They can be placed in a tee fitting for in-line use. CPVC body with 3/4" NPT thread on both ends withstands temperatures up to 80°C.

B. Submersible electrodes are permanently encapsulated in a 3-ft pipe - perfect for tank installation. ABS plastic body withstands temperatures up to 80°C.

C. Semi-domed bulb electrodes with solution ground have a unique surface design that protects electrode from particulates and increases flow across the junction to keep the bulb clean. Graphite body acts as a solution ground. Withstand temperatures up to 100°C.

D. Self-cleaning flat electrodes have an innovative flat surface that prevents solids buildup. CPVC body with 3/4" NPT thread on both ends withstands temperatures up to 80°C.

E. PTFE junction electrodes are excellent for simple wastewater applications. PTFE junction and polymer gel reference electrolyte resist clogging. CPVC body with 3/4" NPT thread on both ends withstands temperatures up to 80°C.

F. PTFE junction electrodes with solution ground are excellent for tough wastewater applications. Solution ground pin eliminates ground loop and electrical noise problems. PTFE junction and polymer gel reference electrolyte resist clogging. Ryton body with 3/4" NPT thread on both ends withstands temperatures up to 100°C.

• Include BNC connector
• Built-in Pt RTD sensor with stripped ends for temperature (ATC) element
• ORP electrodes feature Pt band sensor
• Use electrodes with solution ground with our pH 200, 800, or 1000 controllers in areas with high electrical noise
