Versatile HQd meters offer a large graphic display with backlight, and the intuitive user-interface provides guided calibration, setup, and measurement routines to simplify meter operation. These convenient kits include the dual-input multiparameter meter and probe to measure pH/mV, ISE, and ORP with temperature. Then simply purchase additional IntelliCAL smart probes for other parameters such as conductivity and LDO.

Meter can automatically or manually log up to 500 measurements with probe serial number, current calibration data, user ID, sample ID, time, and date. Use the USB port to download data to a PC or flash drive.

The HQd series uses precalibrated Hach IntelliCAL smart probes that store their own calibration data and identification. The meter recognizes each probe, so you can easily switch probes, and the meter is automatically set up to run the next parameter without recalibrating.
