PRESS RELEASE : New aluminum fixed-point cell from Hart Scientific reduces costs of primary temperature calibrations

AMERICAN FORK, UT — Hart Scientific, a division of Fluke Corporation and a world leader in temperature calibration products and services, announces the model 5947 metal-cased aluminum fixed-point cell designed to make low uncertainty fixed-point calibration practical up to 660.323 °C, without the overhead of a primary standards laboratory.

Unlike the traditional quartz-encased cell, this stainless steel–encased cell does not require courier shipment and is much less susceptible to accidental breakage. Its ultra pure (>99.9999 %) metal and 156 mm (6.14 in) immersion depth provide ± 2 mK uncertainties that rival those of a traditional quartz cell, but the Hart 5947 fixed-point cell is half the cost to purchase and maintain. In the Hart Scientific 9260 mini furnace, the cell provides a long enough plateau for a full day’s work with a realization uncertainty of ± 4 mK.

Fluke Corporation, Hart Scientific Division, designs, manufactures, and markets temperature measurement and calibration equipment. The Hart Scientific product line includes primary standards, thermometer readouts and probes, temperature baths, industrial calibrators and software. Primary and secondary laboratories, as well as a growing number of manufacturing companies who rely on precise temperature controls for manufacturing processes, use the equipment. These industries include pharmaceuticals, petrochemical, semi-conductor, aerospace, food products and others.
