New electronic humidity indicator from
Brownell
Brownell has introduced an electronic humidity indicator as an alternative to paper and chemical colour based indicators, which shows RH, ambient temperature and dewpoint
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

Brownell has introduced a dry nitrogen and gas purge improver, NEPS1000 Advantage, which can be used with most dry gases including argon, helium and SF6
The new electronic humidity indicator 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 to specify an operating performance range for systems and instruments.
The electronic indicator is mounted in a robust IP68 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 five years. Request a free brochure from Brownell ...
