Benchtop meter for Water Quality
- Hach - HQ430d
- Designed for drinking water and wastewater professionals.
Designed for your water applications, the Hach HQ430d laboratory meter is an advanced meter that takes the guesswork out of measurements.
HQd™ meters connect with IntelliCAL™ probes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time.
- 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 - IntelliCAL™ 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
Single input channel for flexible measurement of pH, Conductivity, 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.Convenient kit includes everything you need to start testing
