RHapid-Cal Humidity Generator Fast, portable humidity probe and logger calibration with accredited 1 % RH system accuracy

Humidity calibration in the laboratory or on-site in the field The Fluke Calibration 5128A RHapid-Cal Humidity Generator is a portable humidity generator for calibrating a large workload of probes in the laboratory or on-site in the field. It is used by corporate calibration/research labs and independent calibration labs where humidity measurement is critical to prevent spoilage of products in industries including pharmaceuticals, medical devices, semiconductors, chemicals, and food production. In the lab, the 5128A calibrates humidity probes 33 % faster than a two-pressure generator. In the...

5128A overview Display shows set points and actual temperature and humidity, plus the calculated dew point. Soft keys on the control panel make it easy to cycle through the command menu. Mixing insert causes the air to circulate for better temperature and humidity uniformity inside the insert. Desiccant cap provides easy, front-panel access to desiccant cartridge. Sample In/Out port draws and returns gas to the working chamber. Used to measure the chamber’s dew point with a chilled mirror instrument. Inlet/outlet holes and fan filters. Fill inlet for filling the humidity generator with distilled...

Seven key features of the 5128A RHapid-Cal Humidity Generator 1 Best-in-class system accuracy for dependable humidity probe calibration The 5128A RHapid-Cal offers a best-in-class humidity system accuracy of ± 1.0 % RH (7 % to 80 % RH, 18 °C to 28 °C) which includes all known sources of error such as stability, uniformity, drift, and calibration uncertainty. Calibrate with confidence using an instrument with comprehensive specifications. Most competing generators don’t specify system accuracy. Their specifications can be complicated and confusing, making it difficult to know how to apply them...

5 Compact size and lightweight for easy transport The 5128A RHapid-Cal measures 237 mm high x 432 mm wide x 521 mm deep (9.3 in x 17 in x 20.5 in) and weighs just 15 kg (33.06 lbs). It can be easily carried to any desired bench space in the lab or transported on-site to a field work location. Its front-loading internal desiccant cartridge design adds convenience and ruggedness. In comparison, a two-pressure humidity generator is practically limited to laboratory use because of its large size. It includes a generator, compressor, and supporting equipment. A “small” two-pressure generator requires...
