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.

HACH LANGE is currently running a promotion for UK customers who already own an HQd meter – until 1st September 2009 they will receive a 50% discount on an HQd Firmware Kit which updates the unit to the latest version and enables easier data download to a PC.

Summarising the advantages of the HQd platform HACH LANGE laboratory sales manager Matt Dillon says, "HACH LANGE customers expect accuracy and reliability, but the HQd platform of smart sensors and meters delivers a new level of simplicity and flexibility to customers in a broad range of industries from the utilities to environmental research and from manufacturing to laboratory analysis."
