The Fluke Calibration Fluke5960A Triple Point of Argon System enables primary standards laboratories to realize the argon triple point using a consistent, reproducible process with the lowest uncertainty of any commercially available system. The Fluke Calibration system produces a 30-hour temperature plateau and providesmultiple entrant wells to increase SPRT calibration efficiency and throughput.
Low calibration uncertainty
A number of technology advancements are designed into the Fluke Calibration Fluke5960A system to achieve a low uncertainty of 0.25mK. For example, the argon cell is carefully built with an ultra-clean process using 99.9999 % (six nines) purity argon resulting in an uncertainty factor from impurities of 0.015mK. The deep, 480mm immersion depth of the entrant wellminimizes the effects of stem conduction to less than 0.01mK and radial uniformity to less than 0.05mK.
High lab throughput
The Fluke5960A system utilizes liquid nitrogen (LN2) in a Dewar vessel surrounding an argon cell to achieve –189.3442 °C. A digital controller combined with a heatermaintains a temperature plateau lasting up to 30 hours with 0.1mK variation without using complicated pressure controls. By regular renewal of liquid nitrogen in the system, the plateau length can even be extended to four days. The system’s long, stable temperature plateau lets you carry out your SPRT calibrations with better quality andmore efficiency. Four entrant wells increase lab productivity by allowing you to calibrate four SPRTs simultaneously.
Ease of operation andmaintenance
The display panel of the 5690A provides a simplemenu structure with soft function keys for setup and programming the argon system. The readout displays simultaneously the set-point temperature, actual control sensor temperature and percent heater power. The display is selectable in eight languages—English, French, Spanish, Italian, German, Russian, Chinese, and Japanese. Applying positive pressure with helium or dry nitrogen to an entrant well port prevents your SPRTs from being bound in the entrant well by freezingmoisture. You can insert and remove SPRTs as desired from the system over the duration of a single plateau. Other systems require that you firstmelt the cell in order to add or remove an SPRT.
