specifications. In addition, glove boxes

and isolators – used for handling

moisture or gas-sensitive materials

– benefit from accurate and reliable

humidity measurements. Measuring

humidity in a critical environment can

be especially challenging.

In the food industry the dryers and

ovens used in bread baking and

cereal manufacture require a carefully

controlled humidity level to maintain

consistent quality and high yield, and

to give distinctive characteristics to

the finished product.

▪

Same measurement principle

as in the HUMICAP® sensor

▪

Factory pre-calibrated - no

additional calibration or

adjustment needed

▪

Fully interchangeable

▪

Used in humidity instruments

with ±3 %RH accuracy

In building automation, optimizing

both the temperature and relative

humidity of the indoor environment

enables a greater level of comfort

for occupants than optimizing

temperature alone. Careful humidity

control is a must in museums,

archives, warehouses, and other

environments where humidity-

sensitive materials are stored.

HUMICAP® – The Story of Innovation

Until the early 1970s, hair

hygrometers were commonly

used in radiosondes. At that time,

reliable humidity measurement

was an unresolved challenge

and to solve this, Vaisala began

developing a new type of humidity

sensor using semiconductors

and thin-film materials. The

revolutionary HUMICAP humidity

sensor was introduced two years

later, in 1973, at CIMO VI congress.

HUMICAP was a radical

innovation that changed humidity

measurements for good. The new

technology was groundbreaking:

the sensor had no moving parts,

and due to the advanced use

of semiconductor and thin-film

technologies, it was amazingly

small. The sensor had a fast

response time, good linearity, low

hysteresis, and small temperature

coefficiency.

Despite the fact that the innovation

was designed for a new type of a

radiosonde, the greatest interest

came from elsewhere: people

working in environments as

diverse as greenhouses, bakeries,

warehouses, construction sites,

brick and timber kilns, and

museums. The need for reliable

humidity measurement was

common to all, and instruments

that could do this accurately were

few and far between.

By 1980, a variety of products

based on HUMICAP technology

– from hand-held meters to

industrial transmitters, calibrators,

and other accessories – were

being sold in over 60 countries.

Since its birth, HUMICAP has been

part of Vaisala’s core business,

propelling the company to industry

leadership in the field of humidity

measurement.
