PH8500-MS pH Meter for Small Sample Quantities with GLP Memory Function and Data Output

The Apera Instruments PH8500-MS is a high-precision pH meter designed for testing small sample volumes in limited spaces such as microtubes, narrow vials, or shallow containers. It is equipped with the LabSen® 243-6 pH electrode, which features a slim 6mm diameter and can measure volumes as low as 200 µL—or down to 60 µL with the appropriate micro container. With the ability to measure at temperatures up to 100°C and its integrated temperature sensor, this meter ensures fast, accurate, and ATC-enabled readings across a wide range of applications.

Its waterproof (IP57) and dustproof design, along with a shock-resistant silicone housing, makes the PH8500-MS ideal for both field and lab use. The meter also features GLP-compliant memory storage for 500 data sets and supports real-time USB data transfer for robust documentation and analysis.
