PH850-FT pH meter for surface measurements

PH850-FT pH meter for surface measurements

Description

The PH850-FT from Apera Instruments is a handy and easy-to-use meter for the determination of pH, ORP (electrode sold separately e.g. 301Pt-C) and temperature. The LabSen® 373 pH electrode included in the scope of delivery has a flat glass membrane and is particularly suitable for the reliable measurement of smooth surfaces such as skin, paper, leather, fabric, textiles, etc.. A polyoxymethylene (POM) sheath serves as corrosion protection for the electrode and prevents possible damage from impacts. An integrated temperature sensor allows simultaneous measurement of pH & temperature and enables automatic temperature compensation to be performed. The PH850-FT is protected by a silicone cover and is waterproof and dustproof (IP57), making it particularly well suited for field use, even in harsh environments.

  • Equipped with the LabSen® 373 pH electrode for surface measurements
  • Silicone case provides safe & firm grip and protects from shocks
  • Waterproof and dustproof (IP57) for use in harsh environments
  • Fold-out stand for convenient indoor operation
  • Quick and easy 1- to 3-point calibration
  • Large, illuminated LCD simultaneously displays conductivity value and temperature, as well as additional measurement and calibration information
  • Self-diagnosis supports calibration or troubleshooting

The meter is RoHS and EC certified and has a 3 year warranty (6 months on the electrode).

Electrode

The LabSen® 373 flat pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials and has an integrated temperature sensor. The electrode has a flat glass membrane, which is ideal for reliable measurement of smooth surfaces such as skin, paper, leather, fabric, textiles, etc. A polyoxymethylene (POM) sheath serves as corrosion protection for the electrode and prevents possible damage from impacts.

This electrode has the following features:

  • PTFE connection made of multi-porous Teflon material for better prevention of contamination and clogging
  • Special flat glass membrane for measurements on surfaces such as skin, fabric, paper, etc.
  • Blue gel electrolyte, does not flow and does not cause air bubbles
  • pH sensor technology and materials from Switzerland
  • Long-life reference system that improves the stability of the reference electrode and extends the life of the electrode
  • The POM housing is highly resistant to corrosion
  • Integrated temperature sensor allows autom. Temperature compensation
