Designed for water quality experts, the Hach HQ440d benchtop meter is an advanced laboratory meter that takes the guesswork out of measurements. HQd meters connect with smart probes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The advanced benchtop meter is designed to withstand years of continuous lab use. HQd meters feature a simple user interface that does not require manuals or training to operate. The high-flowing reference and open junction of the pH Ultra electrode included in this package delivers fast stablilzation time even in the most difficult sample types and low ionic strength waters. Standard luminescent/optical dissolved oxygen (LDO) and conductivity/TDS/salinity probes are also included for a complete water quality monitoring solution.

• Flexible benchtop meter makes your lab testing of critical water quality parameters more efficient
• Intuitive user interface for simple operation and accurate results
• Trust your measurements - InliCAL? smart probes store all calibrations in the probe
• Enhance productivity with an ultra-bright screen and large font size for easy to read results
• Convenient kit includes everything you need to start testing

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

  Two input channels for simultaneous measurement of pH, Conductivity, TDS, Salinity, Optical 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 while 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.

  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.

  Convenient kit includes everything you need to start testing
