Intellisense

Intellisense® Wet and Dry Bulb Psychrometer (Hygrometer)

£0.00

The Intellisense® Hygrometer is specifically designed to meet the requirements of the WMO CIMO guide, in line with the Minamata Convention Global Treaty on the phase-out of mercury by 2020.

Our Intellisense® Hygrometer is the “direct replacement” for manual hygrometers, often within a Manual Meteorological Garden.

Its technical capabilities are better than mercury, with datalogging, GPRS and expansion into an AWS with a multiplicity of different sensors for most ground data parameters.

If you, your organisation or your NHMS needs to transition away from mercury-filled instruments in the field, then the Intellisense® Kit is the perfect option.
