Hart Scientific’s new temperature/humidity generator produces humidity atmosphere to ±0.5 percent accuracy

Bench-top generator expands company’s product line

AMERICAN FORK, Utah — Hart Scientific, a world leader in temperature calibration products and services, has expanded its core product base to include temperature/humidity generation. The new Hart Model 5121 Temperature/Humidity Generator is a self-contained bench-top unit that calibrates a wide variety of temperature/humidity measurement instruments and generates RH (relative humidity) with an accuracy of ± 0.5 percent.

Manufactured by Thunder Scientific for Hart, the 5121 produces atmospheres of known humidity values using the “two-pressure” generation principal that was developed and proven by NIST. This principal involves saturating a stream of air with water vapor at a known temperature and pressure to derive RH. By using this principal, the 5121 generates RH with an accuracy of 0.5 percent over the range 0ºC to 70ºC, proving extremely valuable to industries like pharmaceuticals and others that depend on precise humidity measurements over a broad range.

Technicians can now use the 5121 to calibrate humidity probes, data loggers, chart recorders, and hygrometers reducing the cost and time involved in outsourcing calibration. The 5121 also performs environmental testing and facilitates data evaluation and verification. It comes standard with humidity conversion and calibration automation software that allows technicians to preprogram set points and walk away until the calibrations are complete.

Hart Scientific, a Fluke company, 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.
