Different laboratories can implement different experimental functions. Each laboratory has requirements for temperature and humidity . The temperature and humidity required for each experiment is generally not the same. Most experiments are carried out in a clear temperature and humidity environment. Laboratory environmental conditions directly affect various experiments or test results. Each experiment requires a temperature and humidity monitoring system to provide accurate environmental parameter data for laboratory experiment requirements to ensure that the experiment process has the appropriate temperature and humidity for the experiment. Proceed normally.
The environment in the laboratory includes air temperature, humidity, and air velocity, etc., which has an impact on the personnel and equipment in the laboratory. The suitable temperature in summer should be 18 ～ 28 ℃, the winter is 16 ～ 20 ℃, and the humidity is generally between 30% (winter) and 70% (summer). Except for special laboratories, temperature and humidity have little effect on most physical and chemical experiments, but balance rooms and precision instrument rooms should control temperature and humidity as needed.
Laboratory environment temperature and humidity control requirements:
An important factor for controlling the temperature and humidity of the environmental conditions is to ensure that the temperature and humidity of the experiment can meet the needs of each process of the experimental procedure. We mainly develop the temperature and humidity control range of the laboratory environment from the following aspects.
First, identify the environmental temperature and humidity requirements of various tasks:
Mainly identify the needs of instruments, the needs of reagents, the needs of experimental procedures, and the humanity of laboratory staff (the human body is generally comfortable in the range of 18 to 25 ° C and relative humidity in the range of 35 to 80%, and from a medical perspective, the environment There is a causal relationship between dryness and inflammation of the throat) Considering the four aspects, a comprehensive list of requirements for temperature and humidity control ranges is given.
Second, select and formulate effective environmental temperature and humidity control ranges:
Extract the narrowest range from the list of all the requirements of the above elements as the allowable range of the laboratory's environmental control, formulate the management procedures for environmental condition control, and formulate reasonable and effective standard operating procedures based on the actual situation of the department.
Third, maintenance and monitoring:
Through various measures to ensure that the temperature and humidity of the environment are within the control range, and monitor and record the temperature and humidity of the environment, take measures in time to exceed the allowed range, turn on the air conditioner to adjust the temperature, and turn on the dehumidifier to control the humidity.
Fourth, the approximate range of temperature and humidity in the laboratory room:
The standard temperature in the laboratory is 20 ℃, and the temperature in the general testing room and test room should be 20 ± 5 ℃;
The standard room for line value measurement is 20 ± 2 ℃, the standard room for electrical and radio professionals and the measurement and measurement instrument room for line value measurement are 20 ± 3 ℃, and the relative humidity in the laboratory should generally be maintained at 50 to 70%;
Reagent chamber temperature is 10 ～ 30 ℃, humidity is 35 ～ 80%;
The temperature of the sample storage room is 10 ～ 30 ℃, and the humidity is 35 ～ 80%;
The balance room temperature is 10 ～ 30 ℃, humidity is 35 ～ 80%;
Temperature of moisture chamber is 10 ～ 30 ℃, humidity is 35 ～ 65%;
Infrared room temperature is 10 ～ 30 ℃, humidity is 35 ～ 60%;
Central laboratory temperature 10 ～ 30 ℃, humidity 35 ～ 80%;
The sample room temperature is 10 ～ 25 ℃, and the humidity is 35 ～ 70%.
Ordinary chemistry experiments generally only control the temperature, the laboratory temperature is controlled at 20 ~ 25 ℃, and the humidity is generally below 80%. The temperature of the sample room at room temperature is 10 ℃ ～ 30 ℃, the temperature of the sample room in a cool room is not higher than 20 ℃, and the humidity should be 45-75%. Using a temperature and humidity control system to control the temperature and humidity in the laboratory can be precise and intelligent, ensuring the success rate and accuracy of the experiment.
