Technical Specs |
These double junction probes are of rugged design with an epoxy body housing. Filled with a non-refillable buffer gel, they use a double junction reference system for minimisation of contamination due to clogged pores or ingress of sample. They are designed as a low-power instrument and include built-in conditioning electronics for direct connection to a Data Logger.
The Model 6528A ph probe consists of a pH sensor with a voltage output that varies proportionately to the hydrogen ion activity between a reference electrode and an electrode immersed in an alkaline (basic) or acidic solution.
Model 6528B is an ORP or Redox probe. It measures the Oxidation-Reduction Potential (ORP) of a solution. The ORP value is a measure of the electron activity of a solution containing a reversible chemical reaction system. Typical applications include water treatment and swimming pool or spa water sanitation.
The Model 6528A ph Probe is not shown, the Model 6528B ORP (Redox) Probe is shown to the top/right.
