Lacerta Technology are delighted to announce that due to improvements in manufacturing and supplier agreements they are able to reduce the price of their popular Humidity Controller by around 25%.  

Humidity as an experimental variable in thermal, microscopy and rheological experiments is well known and an important parameter to control or measure.

Lacerta Managing Director Dr John Duncan says “We are always looking for ways of improving the value we provide to our customers and I am delighted that we can pass on the savings we are making in the factory directly to the scientist in the laboratory.”

The Humidity Controller system works by pumping a gas (normally air) through a desiccant into the instrument. A valve, controlled by a humidity sensor (placed in the experimental sample chamber) is used to divert some of the gas flow through a water reservoir and then back into sample. Using this feedback function ensures good control of the humidity within the sample environment with humidity ranges of 10 to 85% can typically being achieved.

Good control is obtained across the whole temperature range by setting the water evaporator temperature to 10°C above the test chamber temperature, thus automatically compensating for the amount of water required to attain constant humidity at that temperature.
