Testo 400, multi-functional measuring instrument, including measurement value store up to 500,000 readings, VAC-module (determination of volume flow with error calc.), battery, Li-cell and calibration protocol.

Complex but not complicated The instrument recognises the respective probe connected and shows the next possible steps in the display.

Measurement data processing with "Retrieval guarantee" - Filing is in a clear tree structure with "Retrieval guarantee" \endash in a large display and, of course, on your PC.

Data memory for monitoring processes - A data memory with up to 48,000 readings is available for long-term measurement. All relevant parameters such as start and finish of measurement, measurement intervals, limits exceeded and date/time can be programmed as required.
