These portable meters measure critical water quality parameters without the need to carry multiple instruments. They connect with smart probes that automatically recognise the testing parameter, calibration history, and method settings to minimise errors and set-up time.

• Intuitive user interface with guided calibration and standard routines for simple operation and accurate results
• Stabilisation alerts and visual measurement lock ensure correct and accurate results
• IntelliCAL™ smart probes store all calibrations in the probe: Allows quick and easy exchange of probes without re-calibrating
• HQd™ smart system records serial numbers, current calibration data, user ID, sample ID, time, and date automatically in the data log for complete GLP traceability
• Rugged, waterproof (IP 67) meters for reliable operation in lab or field environments

Both meters measure pH, conductivity, optical dissolved oxygen (DO), BOD, ORP, ammonia, ammonium, fluoride, chloride, sodium, and temperature. They can be used with any IntelliCAL™ smart probe.
