How it works
The Tekran Hg Mercury Vapour Primary Calibration Unit (Model 2505) utilises a thermoelectrically cooled mercury reservoir and dual temperature sensors calibrated against a US National Institute of Standards and Technology (NIST) traceable source producing exceptionally accurate Hg delivery. The mercury vapour is delivered manually using a high precision, digital gas tight syringe. The unit registers the reservoir temperature and calculates the amount of mercury in a user defined injection volume. The device is portable, operating from either 12 VDC or a standard wall outlet.
The Tekran® 2505 is the most advanced system for ultra low-level mercury vapour calibration, since NIST and other standards organisations have yet to provide the means, methods, or reference materials to assist with this type of measurement.
