Storage temperature and humidity alarm

Product Name: temperature and humidity alarm (switching output) Product Code: 91823401616 Product Model: AT-820BR Description: aluminum housing for wall mounting, blue LCD Chinese liquid crystal display, the device uses Chinese menu push-button set temperature humidity upper and lower limits. Networking via RS485 bus can be used two-way switch output, one temperature output, one temperature output, normally open, normally closed, you can access the control panel. Product Description: Technical parameters: Model AT-820BR split function of temperature and humidity sensor input voltage DC input DC12V Switzerland SHT10 temperature and humidity sensor integrated digital temperature and humidity sensor temperature and humidity probe host split design, temperature and humidity probe to the control panel the most for distances up to five meters, the factory wiring of 1.5 meters, measuring range temperature: -40 ℃ ~ + 120 ℃ Humidity: 0 ~ 100% RH, temperature measurement accuracy: ± 0.5 ℃, humidity: ± 4.5% rh, Resolution temperature : 0.1 ℃ Humidity: 0.1% RH Ambient temperature: -20 ℃ ~ + 70 ℃ Humidity: 5% RH-95% RH non-condensing two-way switch output temperature output: normally open or normally closed, can choose only one mode, the factory is normally open humidity output: normally open or normally closed, can only choose one way, the factory is normally open communication interface RS485, could be linked to a computer connected with the company software, then the software but also with a RS485 to 232 modules, development agreement to provide long-term stability of secondary temperature: less than 0.1 ℃ / Year Humidity: less than 1% RH / Static power consumption of the host consumes 40mA 30mA alarm host size 143 × 95 × 40 mm Installation Wall Features: 1. RS485 2. bus transmission can be centrally managed and controlled 3. LCD liquid crystal display 4. Key-temperature, high humidity, low temperature, low humidity upper limit and lower limit buzzer alarm settings 5. 6. LCD backlight 7. The unique automatic on off The address code (HEX three shown) 8. date and time display Chinese LCD menu selection operation 9. 10. support Modbus RTU protocol Features: ◆ real-time collection of temperature data, collection interval reaches MS level. ◆ products can record tracking room, workshop, warehouse, laboratory and other environmental temperature and humidity changes; ◆ data management software users can analyze the data taken on, WORD or EXCEL and other OFFIC document viewing, and the chart or report archive printed. ◆ two-line Chinese LCD, dual-line display of temperature, humidity data, real-time at night can clearly see the real-time temperature and humidity data; ◆ high stability can work 24 hours a day, is an alternative to the new temperature and humidity transmitter products. ◆ provide data that is read signal communication protocol, customers can be secondary development based on engineering applications, greatly reducing development time and cost.
