HQD® HQ440D Laboratory Dual Input, Multi-Parameter Meter – pH, Conductivity, Optical Dissolved Oxygen, ORP, and ISE

Multiparameter: Plug-and-Play any Two IntelliCAL Probes!

Designed for water quality experts, the Hach HQ440D Laboratory Multi-Meter is an advanced laboratory meter that takes the guesswork out of measurements. HQD® laboratory meters connect with smart IntelliCALⓇ electrodes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The advanced HQD bench meter is designed to withstand years of continuous lab use. HQD laboratory meters feature a simple user interface that does not require manuals or training to operate. The HQD digital meter is ideal for any of the following measurement parameters as a pH meter, a mV/RedOx/ORP meter, an Ion Selective (ISE) meter, a Dissolved Oxygen (DO) meter, a Biochemical Oxygen Demand (BOD) meter, a conductivity meter for measuring electrical conductivity, salinity, resistivity, or total dissolved solids (TDS), in wastewater, drinking water or general water quality applications, soil, and food or beverages applications. A wide range of IntelliCAL electrodes, cell, probes and sensors are available to perform accurate measurements in any sample media types.
