Product Details & Documents

The Hach HQ440d benchtop meter is an advanced laboratory meter designed for water quality experts. It features two input channels for simultaneous measurement of pH, conductivity, DO, BOD, ORP, Ammonia, Ammonium, Fluoride, Chloride, Sodium, and temperature − with any IntelliCAL™ smart probe.

Intuitive user interface for simple operation and accurate results
Automatic probe and parameter recognition
IntelliCAL™ smart probes store calibration data in the probe
GLP compatible: HQd smart system records serial numbers, current calibration data, user ID, sample ID, time, and date automatically
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 PC, printer and keyboards

HQd meters connect with smart probes that automatically recognise the testing parameter, calibration history, and method settings to minimize errors and setup time. The 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.

Suitable applications for the electrodes:
PHC705 + PHC805: General purposes
PHC705A: Alkaline samples
PHC725: Drinking water, low ionic strength (LIS) solutions
PHC729: Surface measurements
PHC735: 'Dirty' samples, wastewater, food and beverage applications
PHC745: 'challenging' samples, wastewater influent and other solutions prone to clogging traditional junctions
PHC108: Semi-solid samples (sludge, meat and cheese)
PHC281: Difficult samples (low ionic strength (LIS), ultrapure, dirty, TRIS, or high-solid content samples)

: All meters are supplied with electrode, pH buffer kit (500 ml), pH storage solution (500 ml), probe stand, 4 AA batteries, power adapter, USB cable for data transfer, quick-start guide, user manual, and documentation CD.
