Data Logger testo 175 H1

The testo 175 H1 is equipped with an USB and SD card interface, which makes reading out data quick and easy. The significantly larger memory capacity and the power supply via commercially available batteries are further advantages.

Security:

• Data security thanks to non-volatile memory - even if the batteries are flat, recorded measured values are not lost.
• Password protection prevents unauthorised changes to the measurement statistics.
• Anti-theft device - with the help of a wall mount, the loggers can be permanently installed and secured against theft by a lock.

User-friendliness:

• Two standard interfaces (mini-USB and SD card) allow easy programming and readout of the loggers by connecting directly to the PC - no additional interface for readout is required.
• Large display for easy reading of measurement data - thanks to backlighting at the touch of a button, even in poorly lit rooms.
• Ease of use thanks to one-button menu structure - one click on the "Go" button and the recording of the measured values starts.
