The Benetech GM1365 is a compact USB data logger for temperature (-30 to 80 °C) and relative humidity (0 to 100 %RH). It stores up to 32256 readings, shows current, max and min values on its LCD, warns through an overflow alarm LED and downloads its data to a Windows PC.
The Benetech GM1365 is a compact, low-power data logger that combines signal sampling, display, storage and analysis of temperature and relative humidity. It measures from -30 to 80 °C and from 0 to 100 %RH and stores up to 32256 readings, providing continuous environment monitoring, alarming and recording.
The logger plugs directly into a PC USB port like a flash drive. With the supplied Windows software you set the sampling period, recording interval and upper / lower alarm limits, then download, review, clear and print the recorded data. Its LCD shows the current, maximum and minimum readings together with limit-overflow indicators and a battery level alert.
A bracket with screw fastening and a transparent waterproof cover protect the device from moisture and dust, while an overflow alarm LED signals readings outside the set limits. Typical applications include the medical, food and agriculture sectors, laboratories, electronics, air conditioning, weather service, archives management, archaeology, fibre manufacturing and cold chain logistics.
