ENVEA - Model AutoCal -Automatic Calibration Unit for UT-3000

This is an accesory for the UT-3000 Mercury Ultratracer in monitoring systems at low to intermediate mercury concentrations. The Mercury Instruments Automatic Calibration Unit consists of a specially designed mercury vessel containing elemental mercury of high purity, surrounded by an aluminium jacket cooled by a thermoelectric cooler. For automatic calibration a motor driven syringe extracts a defined volume of mercury saturated gas and feeds it to the UT-3000 Ultratracer.
