Before ordering

Confirm the supplied model version, calibration procedure, temperature operating range, battery type and package contents. The earlier title describes the tester as waterproof but gives no ingress-protection rating or immersion limits; follow the manufacturer's documented restrictions rather than assuming unrestricted immersion.

Calibration buffers, electrode storage solution and other accessories are not documented as included. Confirm suitability for samples other than freshwater before purchase.

Care

Follow the manufacturer's calibration, electrode cleaning and storage instructions. The earlier generic 0.5 kg weight is not confirmed as instrument or packed weight.
