A large range of humidity indicator plugs are available. These externally mounted color change humidity indicators are for determining relative humidity inside rigid containers, electronic enclosures, optical cavities and flexible moisture-vapor-proof bags. The DT1 series can be used in conjunction with a static type desiccator. Mounting options include thread mounting into enclosure, panel bushing or crimp nut.

RFI humidity indicators plugs are also available by request.

Drytech also manufactures a range of humidity indicator plugs, which conform to MIL-I-26860. The Illustration below depicts a standard 2100 Series aluminum indicator body. It may be fitted with a single 40% RH (relative humidity) indicating paper or be provided with a multi level RH indicator. These plugs are externally mounted, color change humidity indicators for determining relative humidity within rigid containers and equipment, and also for use in flexible moisture vapor-proof envelopes or bags.

Traditional humidity indicator papers rely on a distinctive colour change usually from blue to pink to signify a dry to wet humidity change. The humidity indication range for paper indicators is from 10% to 70% relative humidity although this must be specified at an ambient temperature and tolerance range.

The new Electronic Humidity uses a polymer humidity sensor combined with temperature sensor to provide a digital display reading of relative humidity, ambient temperature and dewpoint.

Dewpoint indicates the temperature to which the system or instrument can be cooled before condensation (or frost) will occur. This qualifies dewpoint as a quality control standard for specify an operating performance for systems and instruments.

The Electronic Indicator is mounted in a robust IP67 enclosure with membrane press switch to activate the three readings in sequence. Optional thread mounting or bulkhead flange fixing is available.

The operational battery life is typically 5 years.

ERhi is the latest in innovation from DRYTECH and gives a new take on an old technology. The Electronic Relative Humidity Indicator combines RH, Temperature and Dew Point Display all into a single unit.
