The MHT humidity checks allow you to calibrate and justify probes, portable instruments or transducers. They are small, handy, and insensitive to orientation and are best suited for field- and on-site calibration. The humidity checks contain a saturated salt solution which maintain an equilibrium humidity specific for every salt solution within the chamber. Chambers are available in the range of 0 to 100%RH. The equilibrium humidity of each salt solutions has been agreed upon in international interlaboratory comparison.
