Designed for your water applications, the Hach HQ40d portable meter is an advanced meter that takes the guesswork out of measurements. HQd™ meters connect with InliCAL™ probes that automatically re

Portable meter measures critical water quality parameters - without the need for multiple instruments

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

Intuitive user interface for simple operation and accurate results

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

Trust your measurements - InliCAL™ 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.

Designed for demanding conditions

Rugged, waterproof (IP67) meter provides worry-free, reliable operation in lab or field environments.
