Twelve Probes for One Smart Meter

Hach Lange has announced a further suite of IntelliCAL™ sensors for use with its HQd digital water quality meters. As a result, users will be able to swap sensors quickly and easily for the measurement of six key parameters (BOD, Conductivity, DO, ORP, pH, and sodium).

Ruggedised sensors with a choice of cable length (from 1m up to 30m) are available for some parameters in addition to versions to suit challenging conditions, such as low-ionic strength water. Uniquely, all IntelliCAL™ probes interchange fully with a single HQd meter, which recognises both the probe and its calibration history.

Operation of the HQd meters is further simplified with a large illuminated graphic display that guides users quickly and clearly through the measurement procedure. The operator and sample names are displayed and recorded, and the meter gives both visual and audio indication of stable readings. It can even remind users when calibration is due, so the need for operator training is minimal.

All IntelliCAL™ probes feature advanced sensor technology. For example, the dissolved oxygen and BOD probes feature HACH LANGE’s revolutionary LDO™ technology (luminescent dissolved oxygen) which means no frequent electrolyte or membrane replacement is necessary, just an annual change of sensor cap.
