What are the main points of the temperature and humidity meter pay attention to?

Instrument detailed introduce for everybody below: temperature and humidity meter display: 1, heat storage afraid, afraid of tide, the quality is easy to change goods warehouse, warehouse should be configured between one or several temperature and humidity meter, in different construction, different structure, different floors and goods ( Categories) All should configuration or at least one to several configuration storage temperature and humidity meter, storage warehouses, general merchandise configuration can choose typical warehouse. 2, between the warehouse temperature and humidity meter, if only one configuration, should be placed in the central position of the warehouse in between, and the temperature and humidity meter suspension on the special support, if the configuration of two or more, in addition to the suspension is a central part between the warehouse, the rest of the temperature and humidity meter can need according to the actual situation or observation, discretionary choice hanging position. 3, temperature and humidity ride height to distance from the ground 1 meter. It is advisable to 5 m or so, basically keep in fit eyes straight forward for observation. 4, temperature and humidity meter suspension to keep a certain distance with commodity goods crib, generally in more than 1500 px, for ventilation, the observed data accurately. 5, in order to better grasp the climate change, the conditional warehouse at the empty warehouse, choose good observation sites, set up the screen, also can not outside the warehouse between sun point-blank, patronage ventilated place hang a temperature and humidity meter, to observe the change of outside temperature and humidity between warehouse. Other note 1 of temperature and humidity meter, humidity sensors are sealing, to protect the measuring accuracy and stability, and should be avoided in acid, alkali and containing organic solvents used in the atmosphere. Also avoid using dust in the larger environment. For the correct reflection to measure the humidity of the space, also should avoid sensors placed too close to the walls or the flow of air is not blind Angle. If the room is too large to be measured, it should be placed more sensors. 2, some humidity sensor to power supply requirement is higher, otherwise will affect the accuracy of measurement. Or mutual interference between sensors, even unable to work. When using, should according to the technical requirements to provide appropriate, conform to the requirements of the precision of power supply. Sensor need for remote signal transmission, to pay attention to the attenuation of the signal problem. When the transmission distance of more than 200 m or more, the proposal chooses humidity sensor output signal frequency.
