LabSen 551 Plastic Spear pH Electrode for soil (AI3106)

LabSen 551 Professional Combination pH Electrode for Direct Soil pH Testing, BNC Connector

 

Description

  • Proprietary pH sensor technology and materials from Switzerland
  • Special LabSen Spear pH sensor tip, ideal for direct soil pH testing. No more slurry making.
  • POM housing, ideal for use in harsh environments
  • Polymer Electrolyte - No more clogged junction
  • Long-Life Reference System, improving the stability of reference electrode and prolong the service life of the electrode

 

Backed by proprietary Swiss sensor technology and materials, the LabSen 551 Combination pH Spear Sensor Electrode is designed for testing soil directly.

Long-Life Reference System – The LabSen 551 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 temperature changes. It improves the stability of reference electrode and prolong 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 551 pH electrode adopts a spear sensor tip, which is ideal for directly testing semi-solid samples like soil.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors, such as Apera Instruments MP511SX811PH700PH800PC800PH820 and PC820. Temperature sensor is not built-in. Users need to have a separate temperature (ex: Apera Instruments MP500) probe to enable ATC or manually input temperature to realize temperature compensation.

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