If you need to do calibrations at the triple point of argon but don’t want the complexity and cost of using an argon triple point cell, Fluke Calibration's Model 7196 LN<sub>2</sub> Comparison Calibrators will solve your problems. And they do it for less than half the price of other argon triple point simulators.

The nominal boiling point of nitrogen is –196°C at one atmosphere of pressure. The defining triple point of argon is –189.3442°C. While there is a difference between the nominal boiling point of nitrogen and the argon triple point, the difference can be corrected for mathematically, and an uncertainty of less than 2 mK from the actual argon triple point is achievable.

Fluke Calibration's LN<sub>2</sub> Comparison Calibrators consist of a super-insulated glass dewar, a high-purity copper block, and a precision-fit lid. The dewar is filled with LN<sub>2</sub> and the copper block is suspended in it; an SPRT is inserted into the block and a calibration is performed against your own calibrated SPRT. The <strong>7196-4</strong> includes four 8-mm (0.32") wells. The <strong>7196-13</strong> includes five 8-mm (0.32") wells and eight 6.35-mm (0.25") wells.

Fluke Calibration's LN<sub>2</sub> Comparison Calibrators are neither expensive nor complicated to use. If you need supporting data or would like to discuss the theory of operation of an LN<sub>2</sub> Comparison Calibrator, call Fluke Calibration today.
