Choose among different models, including the three-input HQ4000 series, dual-input HQ2000 series, and single-input HQ1000 series. These meters offer a possibility for wide range parameters to be measured in laboratory – eliminating the need for multiple pieces of equipment. The HQ Series is for water quality professionals who perform electrochemical analysis in field as well as in laboratory. Most measuring issues are caused by incorrect calibration procedure. With the HQ Series’ illustrated, step-by-step on-screen guided calibration and troubleshooting procedures, calibration has never been so fast and simple. Both standard laboratory and rugged field Intellical smart sensors are available to measure a wide variety of parameters including pH, Conductivity, Total Dissolved Solids (TDS), Optical Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and Temperature. Moreover, intellical probes are automatically recognised by meters, with their own calibration history and method settings in order to minimise errors and setup time. They feature proven technology to deliver superior accuracy and response times – even when measuring challenging samples or operating environments.
