Description
HVACR Tester for temperature, relative humidity, CO2, TVOC and light intensity / 4GB memory / Power over Ethernet / MQTT / Email alarm / HTTP / FTP
The HVACR tester is used to measure and store environmental data such as temperature, humidity, illuminance, CO2 content and TVOC concentration. The HVACR tester also calculates the dew point, absolute humidity and the water vapor content in the air. The HVACR tester is used for stationary monitoring of laboratories, greenhouses, medicine and food stores, museums, etc. The data measured and calculated by the HVACR tester are stored in the internal memory and can be called up via Ethernet and sent to the user. In addition to storing the measurement data, the HVACR tester can send alarms by email or display them on a website. The HVACR tester can be supplied via a power supply unit or autonomously via Power over Ethernet. An internal battery is built into the HVACR tester to buffer the memory and the settings.
In addition to the built-in Ethernet interface, the HVACR tester also has an RS485 interface available to the user. This can be addressed via Modbus RTU. The user can communicate with the HVACR tester via Modbus TCP / IP, HTTP, FTP via the Ethernet interface. A web and FTP server as well as a DHCP and SMTP client complete the functionality of the HVACR tester's network interface.
