NIST Traceable Mercury Calibrator (Option)
The MC-3000 is used for generating a continuous stream of a mercury vapor loaded gas stream in order to check or calibrate mercury analyzers. It is also suitable for all those applications where a gas stream with a preset and constant mercury concentration is needed.
- NIST Traceable (NIST Vendor Prime Report # 639.03-12.141) "Optional NIST user prime certification"
- ca. 10 ... 500 µg/m³ Hg and higher upon request
- Compact sized and portable
- No permeation principle - no need to calibrate the calibrator
- Microprocessor controlled
- Easily switch between the NIST or Standard mercury vapor equation
Additional Product Details
Principle of Operation for Mercury Calibrator
An exactly adjustable carrier gas stream (normally air) is loaded with mercury in a first step. In a second step the gas is supersaturated by cooling. Subsequently the excess mercury is condensed in a special cell to get exact saturation. The gas is then diluted, the dilution ratio is continuously adjustable
that final concentrations within the specified range can be obtained.
Construction of Mercury Vapor Generator
The flow regulators and displays are mounted onto the front panel and are easily accessible. For
mobile use the aluminum case has two carrying handles. The mercury containers are mounted inside of the case. The quantity of mercury is sufficient for the whole life time of the calibrator.
Operation of MC 3000 Mercury Calibrator
Using the MC-3000 is easy: The device is placed on a flat surface and connected to the carrier gas source, for example a compressed air line. A portable air pump with a tank is delivered as an accessory. The MC-3000 is then switched on and the desired dilution ratio is selected according to a table which comes together with the calibrator. After waiting for about 30 minutes for stabilizing the saturation temperature is read from the display and the concentration is calculated from the table.
