LabSen®333 POM APERA pH – Temperature Electrode for Wastewater Treatment

The LabSen®333 is a 3-in-1 pH/temperature combination electrode backed by proprietary Swiss pH sensor technology and materials. This temperature-compensated pH electrode is specifically designed to test wastewater, emulsions, suspensions, and samples containing proteins and sulfur compounds. (This is a replacement probe for the Apera Instruments SX811-WW Portable pH Meter for Wastewater).

The LabSen features a distinctive blue hemispherical glass membrane—delivering faster response time, superior reproducibility, and exceptional durability against mechanical shock. This robust design stands in stark contrast to fragile traditional glass bulb membranes.

Equipped with a long-life reference system comprising a glass tube, AgCl, and silver reference wire. The upper end of the fine glass tube is packed with cotton to prevent reactions between AgCl and electrolyte during temperature fluctuations, significantly enhancing reference electrode stability and extending electrode service life.

The solid polymer electrolyte maintains direct contact with test samples, offering pressure resistance up to 6 bar—ideal for suspended solids and wastewater testing. No more frustrating clogged junctions.
