HQd-Series Portable & Benchtop Meters

HQd Benchtop Meters


Flexible benchtop meter makes your lab testing of critical water quality parameters more efficient

Two input channels for simultaneous measurement of pH, Conductivity, Optical Dissolved Oxygen, BOD, ORP, Ammonia, Ammonium, Fluoride, Chloride, Sodium, and temperature - any IntelliCAL™ smart probe.

Intuitive user interface for simple operation and accurate results

Guided calibration and check standard routines reduce calibration errors while stabilization alerts and visual measurement lock ensure that you can trust the accuracy of the results.

Trust your measurements - IntelliCAL™ smart probes store all calibrations in the probe

Calibration history allows quick and easy change out of probes without re-calibrating. The 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..

Enhance productivity with an ultra-bright screen and large font size for easy to read results

Internal USB ports simplify data transfer, peripherals, and software updates and connection to PCs printer and keyboards.
