Apera Instruments LabSen 333 POM-Body pH Electrode for Wastewater Treatment, with Built-in Temperature Sensor, Replacement Probe for SX811-WW Portable pH Meter

Backed by proprietary Swiss pH sensor technology and materials, LabSen 333 POM-body pH Electrode is designed for testing complex water solutions such as wastewater, emulsion, suspension, and samples containing protein and sulfide.

Long-Life Reference System – composed of a glass tube, AgCl and a reference silver wire.

The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when temperature changes.

It improves the stability of reference electrode and prolong the service life of the electrode.

Polymer Electrolyte – The solid polymer electrolyte is in direct contact with test samples.

The anti-pressure capacity can reach up to 6 bars, making it ideal for testing suspension and wastewater.

No more frustrating clogged junctions.

Housing Material: POM; Temp.

Sensor: NTC 30kΩ; Junction: Double-Pore; Reference: Long-Life; Electrolyte: Polymer; Length: 120mm; Diameter: 12mm;
