Who is HANNA Instruments?

Hanna Instruments started in Italy in 1978 and is now based in Woonsocket, Rhode Island, USA. The company designs meters, testers, titrators, and electrodes for measuring pH, conductivity, temperature, and dissolved oxygen across water quality, food safety, agriculture, and laboratory testing.

SmartLabs stocks a small, focused selection of HANNA products in South Africa: a pocket pH tester, calibration buffer sachets, and electrode cleaning solution. It is a compact field and lab testing range for accurate on-the-spot pH readings.

HANNA's product range

SmartLabs stocks a small, focused HANNA range rather than their full catalogue.

  • HANNA pH testing

    Field and classroom pH testing

    The HANNA pocket pH tester gives a direct digital reading at 0.1 pH resolution, quick enough for classroom demonstrations, water quality spot checks, and general lab use where lab-grade accuracy isn't required.

  • HANNA calibration buffers

    Calibration before use

    Single-use calibration buffer sachets at known pH values let you check and adjust the tester's reading before each testing session, which is the single biggest factor in getting an accurate result from any pH meter.

  • HANNA electrode cleaning solution

    Electrode care and cleaning

    General purpose cleaning solution clears residue and buildup from the electrode tip between uses, protecting the sensor and keeping future readings accurate. A quick rinse after cleaning is all that's needed before storage.
