Free Ground Shipping On All Orders Over $1500!*
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 PHC725 is a digital, combination glass-body electrode with a refillable KCl reference and built-in temperature sensor. The PHC725 utilizes Red Rod technology to deliver exceptionally fast response times and stable, accurate measurements. It has an annular ring junction and is ideal for measuring pH in a variety of applications, including laboratory measurement of drinking water and low ionic strength (LIS) solutions.
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.
