Description

Designed for water quality experts, the Hach HQ440D Laboratory Multi-Meter is an advanced laboratory meter that takes the guesswork out of measurements. HQD digital 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 Laboratory Meter is designed to withstand years of continuous lab use. HQD bench meters feature a simple user interface that does not require manuals or training to operate. The IntelliCAL PHC705A is a digital, combination glass-body electrode with a refillable KCl reference and built-in temperature sensor. The PHC705A utilizes Red Rod technology to deliver exceptionally fast response times and stable, accurate measurements. It has a porous pin junction and its special pH glass composition makes ideal for measurements in alkaline samples.

Features

Two input channels for simultaneous measurement of pH, Conductivity, Total Dissolved Solid (TDS), Optical Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Oxydo Reduction Potential (ORP/RedOx),

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.

Calibration history allows quick and easy change out of probes without re-calibrating.
