  • Swiss pH sensor technologies and raw materials
  • Protelyte – a tasteless, odorless, and micro organism-safe electrolyte that fully complies with EC Regulation 1935/2004 for safe contact with food products. This makes it an optimal choice for accurate measurements in biotechnology applications, including biological fluids, enzyme solutions, and protein-containing solutions, TRIS buffers, etc. as well as in food and beverage applications e.g. milk, yogurt, jam, sauce, etc.
  • S-type lead-free glass membrane with faster response rate, and high impact-resistance
  • Patented pH/temperature combination structure, increasing the temperature response time by 40% compared to conventional isolated built-in thermistor
  • The blue gel inner electrolyte eliminates the chance of any air bubbles inside glass membrane.


Backed by proprietary Swiss sensor technologies and materials, Apera LabSen 823 Glass-body pH/Temp. Electrode is designed for testing milk, yogurt, cream, jam, sauces, and other protein-containing liquid. The electrode adopts a Silver Ion Trap reference system and Protelyte reference solution to prevent the junction from being blocked or contaminated by proteins. LabSen's blue glass membrane has a faster response time, better repeatability, and is built tough, highly resistant to general impact (totally differentiates from the traditional fragile glass bulb membrane). The electrode can be tested in high-temperature samples (up to 225˚F). The Patented pH/Temperature combination structure places the temperature sensor in an independent cavity under the pH glass membrane. With the built-in heat-conducting medium, the temperature sensing speed can be increased by 40%, hence the response time and stability of the pH electrode are greatly improved.
