Humidity, Temperature & Dew Point USB Data Logger EL-USB-2 Lascar

Mã sản phẩm: EL-USB-2 |
Thương hiệu: Lascar

Giá bán: Liên hệ

The user can easily set up the logging rate and start time, and download the stored data by plugging the module straight into a PCs USB port and running the purpose designed software under Windows 2000, XP or Vista(32-bit only). Relative humidity, temperature and dew point (the temperature at which water vapor present in the air begins to condense) data can then be graphed, printed and exported to other applications.
