Apera LabSen 553 Plastic Combination Spear pH/Temp. Electrode

LabSen 553 Plastic Combination Spear pH/Temp. Electrode by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 553 3-in-1 pH/Temp. Spear Electrode/Sensor/Tester is designed for testing soil directly (This is a replacement probe for Apera PH850-SL, PH9500-SL).

Long-Life Reference System - The LabSen 553 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 makes the electrode hard to be contaminated and maintenance-free.

Special Glass Membrane - The LabSen 553 pH electrode adopts a spear sensor tip, which is ideal for directly testing semi-solid samples like soil.

Compatible Apera Instruments' meters: 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 by Apera Instruments.
