Analytical Instrumentation & Environmental Monitoring


Portable digital liquid anlaysis systems

January 2007 Analytical Instrumentation & Environmental Monitoring

Hach has released the new HQd series of portable digital meters. They use the new IntelliCAL digital probes to monitor pH, conductivity, and dissolved oxygen. The HQ40d has dual probe input and simultaneously measures two different probes (ie, pH and D.O.) so testing of two different parameters of the sample can be done.

Both the HQ40d and the single-input model HQ30d are smart, intelligent meters that store probe serial numbers, calibration history, user ID, time, date and user location, with the facility to store 500 point event logs.

Being digital the probes can be mixed and matched without the necessity of re-calibration. The IntelliCAL probes are automatically recognised by the HQd meters, so probes are easily interchangeable and each intelligent probe stores its calibration history and can be reliably used in harsh environmental conditions.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
