Humidity Indicators 50%-90%

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.

Applications:

  • Electronic equipment
  • Electrical equipment
  • Optical equipment
  • Cameras
  • Storage containers
  • Laser systems
  • High voltage junction boxes

MOQ 10pcs

55560/17

This item incorporates a Humidity Indicator and a two-way Breather Valve all in the same housing, thereby saving the cost of an additional hole in the case. The valve has separate and distinct settings for both pressure and vacuum relief.

A desiccator can also fitted using the internal thread on the rear of the unit giving it three functions in one product.

The threads are Alochromes for R.F Screening Continuity.

Indicator levels: 30/50%

55560/21
¾" Thread Humi-Valve

This item incorporates a Humidity Indicator and a two-way Breather Valve all in the same housing, thereby saving the cost of an additional hole in the case. The valve has separate and distinct settings for both pressure and vacuum relief.

There is a separate path to the Humidity Indicator. The Breather Valve is lightweight, rugged, tamper-proof and requires no field maintenance. Corrosion-resistant materials are used throughout. The valve seal is made of silicone rubber. A manual release push button is standard on all Breather Valves. It is used to equalize residual pressure or vacuum differentials in order to make opening the container easier. A gasket, washer and hex nut are provided with each valve.

M25 Thread IHP8 & IHP9 Indicator Plug

This is a split level Humidity Indicator with spanner flats and a knurled finish for easy fitting into equipment.

It can be used in combination with a static desiccator and can be supplied with a natural thread for RF Screening.

We also supply a service kit as we recommend the humidity indicator paper be replaced every 3-5 years.

55591/03
No thread 30/50/70%RH Indicator Plug

This is a three level Humidity Indicator with a flange for fitting into equipment.

It can be used in combination with a static desiccator and has a very low profile so it sits flush and is protected from damage.

900011/01T

Small, practical and cost-effective: The moisture indicators are made from special absorbent paper, certain parts of which are impregnated with cobalt (II)-chloride solutions of varying concentrations. The colouring from blue to purple to pink shows the change in relative humidity in the ambient air. Depending on the indicator’s design, the colours can change in reverse sequence once the air humidity decreases (reversible indicators).

At a test temperature of 20°C (+/– 2°C), the permitted tolerance is +/– 5% relative humidity.
The deviations are approximately 2.5% relative humidity per 5°C above and below 20°C.

The indicators are reverseable and have three languages on them, English, German and French.

ERhi, The New Electronic Relative Humidity Indicator Thread M36x2.

ERHI is the latest in innovation from Brownell and gives a new take on an old technology.

The Electronic Relative Humidity Indicator combines %RH, Temperature and DewPoint Display all into a single unit.

Simultaneous monitoring of ambient temperature, relative humidity and dewpoint.

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. The membrane press switch activates the three readings in sequence.

 

The values of relative humidity, ambient temperature and dew point can be stored over a period of 6 months.

The option “data logging” is available under request.

The operational battery life is typically 5 years.

The operating range of the electronic relative humidity indicator is 5 to 90%RH, -20°C to +15°C dewpoint and -20°C to 60°temperature.

Tests conducted on the product proved that the indicator can withstand a pressure 90 psi.

BLD4332
Large Indicator 4 Level Indicator Plug

This four level Humidity Indicator variation with spanner flats for easy fitting into equipment.

It has spanner flats for easy fitting and also supplied with a back nut for panel or barrier bag mounting.

We also supply a service kit as we recommend the humidity indicator paper be replaced every 3-5 years.
