Thermo-hygrometers are essential pieces of equipment for monitoring humidity; they can be used in different environments for various reasons. Our dew point thermo-hygrometer measures both humidity and temperature which is required for finding out the relative humidity in an area. They measure from -35° to 100°C x 0.1° and from 0% to 100%RH x 0.1%, giving you accurate readings that are simultaneously presented on a 55mm LCD display with backlight. It uses a dew point probe which works by an electronic sensor changing electrical capacitance when it absorbs water. Auto power off happens after 15 minutes of no activity and the low battery indicator alerts you when the battery needs to be replaced. An impact-resistant ABS case helps to protect the internal components from being damaged, it also consists of a rubber moulded grip and a tripod mount bush. Our dew point thermo-hygrometer will help you monitor the humidity in an environment, this could be in varying situations but it is also important to check humidity in places, such as offices, to maintain employee comfort and health. They are supplied with a hard carry case, as well as a battery and they have FREE UK Delivery.
