LabSen® 371 APERA pH Electrode for Flat Surfaces

Fiyat Sorunuz

Flat-surface pH electrode featuring proprietary Swiss sensor technology for measuring pH on skin, paper, leather, fabric, and other flat substrates with enhanced accuracy.

  • Flat glass membrane design for enhanced surface pH measurement accuracy
  • Long-lived reference system with AgCl and silver wire for extended service life
  • PTFE multi-porous junction—contamination-resistant Teflon material
  • BNC connector compatible with multiple Apera pH meter models
  • Temperature range 0 to 80°C (32 to 176°F)
  • No built-in temperature sensor—requires separate ATC probe for temperature compensation

The LabSen® 371 Combination pH Electrode, supported by patented Swiss pH sensor technology and materials, is specifically engineered for flat-surface pH measurement applications including skin, paper, leather, fabric, and similar substrates. The electrode features a flat glass membrane that simplifies surface pH testing and delivers precise measurements. Its long-lived reference system composed of a glass tube, AgCl, and reference silver wire ensures extended electrode service life and improved stability. The cotton-filled upper end of the thin glass tube prevents reactions between AgCl and electrolyte during temperature fluctuations. Equipped with a PTFE junction—a multi-porous Teflon material resistant to contamination—and compatible with BNC connector-based pH meters.

Frequently Asked Questions

Is a temperature sensor built-in to the LabSen® 371 electrode?
No. Users must employ a separate temperature probe (such as Apera's MP500) for automatic temperature compensation (ATC) or manually input the measured temperature for compensation.
Which pH meters are compatible with the LabSen® 371 electrode?
The LabSen® 371 is compatible with any Apera pH meter featuring a BNC connector, including the MP511, PH850, PH8500, PH700, PH910, PH950, PH820, and PC820 models.
What is the primary advantage of the flat glass membrane design?
The flat glass membrane enables easier and more accurate pH measurement on flat surfaces such as skin, paper, leather, and fabric, compared to standard hemispherical electrodes.
How does the long-lived reference system extend electrode lifespan?
The cotton-filled upper end of the thin glass tube prevents unwanted reactions between AgCl and electrolyte during temperature changes, maintaining reference electrode stability and extending service life.
