The Testo 815 (0563 8155) Sound Level Meter is the ideal instrument for the evaluation of sound level in everyday work. The instrument can be used for monitoring measurements in the areas of air conditioning or heating, on combustion plants or at workplaces; in addition, machine or discotheque noise can also be evaluated quickly and precisely.

Using the Fast/slow button, the measurement time can be set from 1 s to 125 ms, in order to better evaluate the noise source. The frequency analysis can also be switched from characteristic curve A to C. The characteristic curve A corresponds to the sound pressure perception of the human ear, whereas characteristic curve C can also evaluate the low-frequency components of a sound.

With the help of the optional calibrator, the measuring instrument can be recalibrated directly on site with the screwdriver provided. The wind protection cap included in delivery ensures correct measurement results when measuring outdoors, and if required can protect the microphone from dirt and dust.


Evacuation of refrigeration systems:

You can carry out evacuations quickly and safely with the integrated vacuum measurement and no additional measuring instruments are needed.

Simultaneous calculation of superheating and subcooling:

The testo 570 automatically calculates superheating and subcooling of the system using up to 3 temperature probes which can be connected at the same time. Ambient temperature or flue gas temperature can also be checked with the third connectable probe.

Tightness testing of refrigeration systems:

The testo 570 can carry out a temperature-compensated leakage test of the system for rough tightness testing. To do this, the system pressure at the start of the measurement is compared with the one at the end and any difference there may be is displayed directly.
