WQ-300 Sensors

Each sensor kit includes pH sensor and 3 x 60-ml pH buffers (either USA or NIST).

For low conductivity measurements (0.01~500 µS/cm). Each sensor kit includes conductivity sensor and 4 x 60-ml conductivity standards. Sensor kits with flow cell are also available.

For wide conductivity measurements (10 µS/cm~2000 mS/cm). Each sensor kit includes conductivity sensor and 4 x 60-ml conductivity standards.

Each sensor kit includes optical DO sensor and its accessories.

The sensor kit includes ion sensor head and sensor head adapter for connecting ion selective electrodes (sold separately). 

The sensor kit includes ORP sensor head, sensor head adapter, and ORP electrode.

Sensor head for 300-P-C pH sensor cartridge

Sensor head for 300-4C-C conductivity sensor cartridge

With sensor head adapter, the ion sensor head can be used with any combination ion selective electrode that has BNC connector.

With sensor head adapter, the ORP sensor head can be used with 9300-10D ORP electrode or other ORP electrode that has BNC connector.
