Overview of high and low temperature constant temperature water bath:

Standards and technical requirements for high and low temperatures,So when customers choose high and low temperature testing instruments,We should communicate with the manufacturer based on the following situations,So as to choose a high and low temperature testing machine that satisfies oneself:Selection of box size and volume: High and low temperature constant temperature water bath will be used to test the product(Components, assemblies, parts, or complete machines)When conducting tests in a climate chamber, in order to ensure that the atmosphere around the tested product meets the environmental test conditions specified in the test specifications, the working dimensions of the climate chamber and the overall dimensions of the tested product should follow the following regulations:

a)Volume of the tested product(W×D×H)Not exceeding the effective working space of the test chamber(20～35)％(Recommended selection20％)For products that generate heat during testing, it is recommended to choose products that do not exceed10%.

b)The ratio of the windward cross-sectional area of the tested product to the total area of the testing chamber on that section shall not exceed(35～50)％(Recommended selection35％).

c)The distance between the outer surface of the tested product and the wall of the test chamber should be maintained at least100～150mm，(Recommended selection150mm).

The above three provisions are actually interdependent and unified. use1Taking a cubic cube box as an example, the area ratio is1：(0.35～0.5)Equivalent to a volume ratio of1：(0.207～0.354)Distance from the box wall100～150mmEquivalent to a volume ratio of1：(0.343～0.512).
