LabSen®851-1 APERA pH Electrode for Cosmetic Products

Fiyat Sorunuz

Professional pH electrode with Silver Ion Trap reference system and conical glass membrane, designed for cosmetics and viscous samples. BNC connector compatible.

  • Silver Ion Trap Reference System with Protelyte Electrolyte prevents junction clogging and protein contamination
  • Unique conical glass membrane design for maximum surface area in viscous samples
  • Robust and durable - high impact resistance compared to traditional fragile glass bulb sensors
  • Compatible with BNC connector pH meters including MP511, PH850, PH8500, PH700, PH910, PH950, PH820, and PC820
  • No built-in temperature sensor - requires external temperature probe (e.g., MP500) for ATC or manual temperature compensation

Frequently Asked Questions

Is this electrode compatible with my pH meter?
The LabSen®851-1 features a standard BNC connector and is compatible with Apera Instruments pH meters including MP511, PH850, PH8500, PH700, PH910, PH950, PH820, and PC820. Verify your meter's connector type before purchase.
How do I perform temperature compensation?
This electrode does not have a built-in temperature sensor. You must use an external temperature probe (such as the MP500) and enable automatic temperature compensation (ATC) in your pH meter, or manually input the sample temperature for accurate measurements.
Why is the conical membrane design beneficial?
The conical glass membrane maximizes the sensor's surface area, making measurements more reliable and easier to perform in viscous samples. It also provides superior durability and impact resistance compared to traditional fragile glass bulb electrodes.
What makes the Silver Ion Trap reference system unique?
The Silver Ion Trap system with Protelyte electrolyte specifically prevents junction clogging and contamination caused by proteins and complex samples commonly encountered in cosmetic testing, extending electrode lifespan.
Can this electrode be used with non-BNC meters?
No, this electrode is designed exclusively for BNC connector compatible pH meters. Using an adapter with incompatible equipment may compromise measurement accuracy.
