  • Response time: 90% signal level: < 1 sec

MSREF Miniature reference electrode

Microsens has developped a miniature reference electrode to work with the MSFET3330. More information can be found in the MSREF Datasheet.

MSFET Interfaces

The MSFET3330 requires a specific interface electronics to drive the sensor and read the sensor output. Microsens offers a range of interfaces with different options. Details on the different interfaces can be found here.

ISFET Measurement Kit

MICROSENS offers a measurement kit for the MSFET 3330 pH sensor.
The kit consists of the following items:
