5 Level - 50, 60, 70, 80 & 90% RH

Short Description



Brownell manufactures a range of relative humidity indicators which provide a signal of the relative humidity ranging from 5% to 90% Rh (at 20°C). Relative humidity indicators can be used in conjunction with desiccators, desiccant bags and moisture adsorbers. Humidity indicators can also be used to monitor the relative humidity inside: cabinets, enclosures, flight cases, pipelines, packaging barriers and instrument cases. A distinctive colour change of blue to pink indicates the transition of the relative humidity from dry to wet.
