All kinds of room temperature and humidity standard reference

There are some rooms or control room, document, etc to temperature, humidity has certain requirements, you will need to a mechanical temperature and humidity meter to test the environment. Models: TH600 types: temperature and humidity meter structure: wall-mountable cover circle: piping materials: SS304 tooth head: no tooth surface diameter: 150 mm temperature range: 0 - 120 c 0 - 100% RH precision: temperature & plusmn; 2%, humidity & plusmn; Table covered: 6% glass of room temperature and humidity standard reference: A class room, including the main transport hub and set up long switches, provincial backbone signalling/province, provincial backbone intelligent network SCP in the province, provincial/provincial backbone telecom data network equipment room and power equipment room, etc. Normal temperature and humidity range: temperature 10 ~ 25 ℃, humidity 40 ~ 70% acceptable range of temperature, humidity, temperature for 10 ~ 26 ℃, humidity 40 ~ 75% B class room: including setting network tandem office, mark bureau, intelligent network SCP, signalling, core network equipment, wireless telephone, data backbone transmission backbone node ( Including man core equipment) , IDC, dial-up server communication room and power equipment room, imported 50000 above the door's mother program-controlled exchange bureau and female domestic program-controlled exchange bureau computer room and measuring room, power room, the exchange of important user service and key departments, transmission and data communication equipment room, long-distance trunk road station and words, etc. Normal temperature and humidity range: 10 ~ 28 ℃, temperature humidity 30 ~ 70% acceptable range of temperature, humidity, temperature of 5 ~ 28 ℃, humidity: 30 ~ 80% C room including 50000 door below female domestic program-controlled exchange bureau, metropolitan area network convergence layer data of power room, computer room and belong to the long distance transmission relay station, etc. Normal temperature and humidity range: 10 ~ 30 ℃, temperature humidity 30 ~ 75% acceptable range of temperature, humidity, temperature of 5 ~ 30 ℃, humidity 20 ~ 80% D class room: including setting fixed telephone module, user access network, metropolitan area network access layer devices ( Village routers, switches,) , DSLAM equipment, cable into the chamber room etc. Normal temperature and humidity range: 5 ~ 33 ℃, temperature humidity 20% ~ 80% acceptable range of temperature, humidity, temperature 0 to 35 ℃, humidity 15% ~ 85% note: acceptable temperature and humidity range is to point to in a short period of time ( For four hours) , allowing the equipment below, or higher than the normal temperature, humidity range of work under the conditions of temperature and humidity range.
