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 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 meters feature a simple user interface that does not require manuals or training to operate. The IntelliCAL PHC281 is a standard combination pH electrode, robust plastic body, refillable with built-in temperature sensor and 1 m cable. PHC281 is intended for laboratory use and specially designed for fast response and stabilisation to measure pH in general purpose water quality applications or in difficult samples such as low ionic strength (LIS), ultrapure, dirty, TRIS, or high-solid content 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.
