Power supply: Layer built cell DC 9V 6F22. Dimensions: 130×66×24mm.
Weight: 200g (with meter, sensor and battery)
Operating ambient: the instrument part, temperature between -20 and 60℃, humidity≤85%.
There will be a drift of ±3%RH, when the humidity above 90%RH that the sensor measured over a long period of time,the drift can revert after lowering.

			Various engineering environment and processing humidity temperature measuring.

			The public architecture and office building humidity temperature measuring.

			The outdoor ambient humidity temperature measuring.

			The humidity temperature equipment and the instrument necessary.

			The humidity temperature monitoring of some places, such as the workshop, the storeroom, the supermarket, the laboratory, the computation room, the breeding shed, and the artificial ambient etc.

Keep attention to clean and be careful to maintain the sensor, especially the sensitive part of the humidity sensor. In order to prevent the damage of the sensor, please do not turn on the protective covering of it if not necessary, if you have turned on the protective covering, please don't use your hands or other tools to touch the sensitive part. Also it should be avoided getting in touch with the oil and grease.

The humidity sensor can prevent dust and noxious gases corrosion, but in the environment that has a lot of dust, the sensor must be wore the pore shield. This shield is made of the metal powder sintered, so not only has good venting quality but also can effectively prevent dust and oil pollution. It should be cleaned in time when the shield accumulated too much dirt. You could use brush to clean it in the warm water with a little detergent, and wash down it with a large amount of fresh water until the water could seep out smoothly from the inside of the shield to the outside, after the clean you must make it dry. The color will get dark gradually when the shield is used for a period of time, this does not affect its performance.
