Entrance guard equipment high and low temperature test method

Entrance guard controller
the last time we introduced the test method of access control equipment moistureproof, today we introduce is access control device of high and low temperature test method.First of all, we want to know, are greatly influenced by high and low temperature of entrance guard equipment usually has the following kinds: entrance guard controller, power supply, optical transceiver, hard disk video recorder, etc.In some areas where day and night temperature difference is bigger, the entrance guard system will sometimes bad, this was the result of under the influence of ambient temperature.So we when doing the access control project, must consider to use environment, targeted selection, ensure the stable operation of the entrance guard system.Here we suggest you had better be to choose industrial-grade (40 ~ 85 - degrees c) products to ensure that the entrance guard system in stable operation of the high and low temperature environment.

so, entrance guard how high and low temperature testing equipment?

here we want to use high and low temperature test chamber, we can simulate the environment temperature to testing equipment.Put the power of the equipment respectively in 85 ℃ and 40 ℃ - environment, the working state of the testing equipment, if you can keep the stable operation of the eight hours work, so we can say that equipment of the high and low temperature performance is qualified.
