Quantitech has announced that the ShurShot HF Catastrophic Leak Detector from PMS has received ATEX approval for monitoring HF in potentially explosive environments.
Quantitech has announced that the ShurShot HF Catastrophic Leak Detector from PMS has received ATEX approval for monitoring HF in potentially explosive environments Quantitech Managing Director Keith Golding says "ShurShot is a highly reliable and cost effective monitor designed to immediately detect and alert for catastrophic HF leaks in refineries, petrochemical plants, or other applications where HF leaks are considered a risk

Monitoring sub-micron aerosols and particulates
Motor manufacturers or indeed anyone interested in studying or monitoring sub-micron aerosols and particulates will appreciate the benefits of sequential mobility particle sizer and counter.
This device is suited for leak monitoring of flanges, pumps, seals, and other components that are at risk of releasing HF." ShurShot produces no false alarms.
Detection is based on very specific reaction of HF with a glass-like coating on the sensor chip.
This coating, in the form of a blue surface on a shiny substrate, is etched away during the reaction.
The surface of the chip is continuously monitored by shining light from a red LED through an optical fibre onto the sensor chip.
The light reflected is picked up by another optical fibre and transmitted back to a photo sensor, where it is converted to an analogue 4-20 mA signal.
As the HF reacts with and removes the coating, the amount of light reflected back increases until all the coating is gone, and then the signal reaches maximum value.
This increase of light intensity, monitored in the form of a current level change, provides a positive indication of detection.
