Telp. 021-60799777 HP. 081215608000 Hygrometers are instruments for measuring the water content of the air in Percentage Relative Humidity ( % RH) . They can also be used to calculate the Dew Point when used with the relavent tables. We offer a selection of hygrometers including wet and dry bulb masons hygrometers, hair hygrometers and whirling hygrometers. Whirling hygrometers, also known as sling psychrometers or aspirated hygrometers, employ the " wet " and " dry " bulb principle to determine % RH.

They are designed to be rotated by hand to provide adequate and constant ventilation of the bulbs.
The spirit thermometer tubes used in these hygrometers have a blue coloured LO-toxâ„¢ filling which has a similar accuracy and better legibility than the traditional mercury filling.
This traditional model has a folding handle and is available in its original design with mercury tubes or with the more environmentally friendly LO-toxâ„¢ blue spirit filled tubes Protection is provided by a canvas carry case.
