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 7196B LN2 Comparison Calibrators will solve your problems. And they do it for less than half the price of other argon triple point simulators.

Fluke Calibration's LN2 Comparison Calibrators consist of a vacuum-sealed stainless steel Dewar Flask, a high-purity copper block, and a precision-fit lid. The dewar is filled with LN2 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.

Two models are available:
7196B-4: Four 8 mm (0.32") wells
7196B-13: Five 8 mm (0.32") wells and eight 6.35 mm (0.25") wells

 

Important: Refer to the User's Guide Supplement for instructions on how to safely fill and use the 7196B.

• Low-cost calibrations to –196°C
• Simple to use
• Uncertainty less than 2 mK

Temperature Nominal -196C depending on atmospheric pressure
Thermal Wells 7196B-4: four 8 mm (0.32") I.D. wells
7196B-13: five 8 mm (0.32") I.D. wells, eight 6.35 mm (0.25") I.D. wells
Both blocks: 275 mm immersion from top of lid to bottom of well, 150 mm immersion into copper block
Dimensions (Outer Diameter x Height) 168 mm x 406 mm (6.6 in O.D. x 16 in)
Temperature Stability Typically better than 2 mK/20 min[1]
