LabSen 333 POM Combination pH/Temp. Electrode for Wastewater Treatment by Apera

Backed by proprietary Swiss pH sensor technology and materials, the LabSen® 333 3-in-1 pH/Temp. The electrode is temperature compensated pH electrode and is designed for testing wastewater, emulsion, suspension, and samples containing protein and sulfide (This is a replacement probe for Apera Instruments SX811-WW Portable pH Meter for Wastewater).

LabSen unique blue hemispherical glass membrane - faster response time, better repeatability, and built tough, highly resistant to general impact (totally differentiates from the fragile conventional glass bulb membrane).

Long-Life Reference System - The LabSen 333 pH electrode adopts a long-life reference system, which is 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 the temperature changes. It improves the stability of reference electrode and extends 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.

Compatible with Apera Instruments' meters such as PH700, SX823-B, MP511, PH800, PC800. May NOT work with other brands' meters because the temperature unit might be incompatible.

The electrode is backed up with a 6-month warranty fulfilled by Apera Instruments.

• Polymer Electrolyte, ideal for testing wastewater and suspension. No more clogged junction.
• Long-Life Reference System, improving the stability of reference electrode and prolong the service life of the electrode
