ABB conductivity analysers are designed to meet the most exacting requirements of our valued customers. The extensive range covers 2 and 4-wire analysers and single or dual-input devices.
Our hazardous area certifications embrace FM, CSA and CENELEC ATEX intrinsic safety. Instruments are available with HART, Profibus PA or DP, and Fieldbus Foundation communications capabilities.

|
High accuracy technique for trace conductivities from ultrapure water to industrial rinse waters. An alternating current is passed between two electrodes in contact with a solution. The transmitter converts the resultant potential difference into conductivity, concentration or specific resistance.

|
|
Traceable calibration instruments for WFI and PW processes in the Pharmaceutical Industry.
|
|
|
Auto-compensating technology for high level conductivity and concentration measurements in high-coating processes.
|
|
|
Non-contact technique providing immunity to polarisation, oily fouling and non-conducting coatings until gross fouling occurs. Measurement of the magnitude of induced AC into a closed loop of solution using two embedded toroids.
