Astles DIW-pH Probe
For Wastewater Monitoring and Control
DIW-pH Probes
Order Codes
DIW-pH with 3m cable: DIW-PH
DIW-pH with 6m cable: DIW-PH-6M​
DIW probes offer a rugged solution for monitoring and controlling pH levels for wastewater treatment. The probes design reduces the build-up of contamination and allows accurate readings to be taken for up to 12 months.
Features:
The DIW-pH is a replacement for the discontinued DIW711 and is a sealed, robust, low maintenance PVC bodied combination dip type electrode.
The electrode incorporates a reference system containing a ceramic junction and gelled electrolyte allowing consistent and reliable pH readings in open vessel measurements.
