GRAS 42AG Multifunction Sound Calibrator, Class 1

Enquiry Item

Developed as an improved replacement for the successful 42AB Sound Calibrator, the 42AG Multifunction Sound Calibrator is specifically designed for fast verification of microphones and sound level meters in the field. It represents new and improved functionalities and is easy to use. There is a real need for a portable and intuitive calibrator that can be used for testing in multiple situations.

42AG meets that challenge as it has a user-friendly interface, automatic compensation for ambient environmental conditions such as ambient air pressure, temperature and humidity as well as two calibration frequencies and levels.

The calibration level, frequency and environmental parameters are displayed on an OLED display. A push on the dB button toggles between 94 and 114 dB. Likewise, a push on the Hz button toggles between 1,000 and 250 Hz. The °C/°F button displays the ambient pressure, temperature and humidity.

The 42AG conforms to standard IEC 60942 for Class 1 sound calibrators, is battery operated and supplied with a protection case, which makes it ideal for in-field verification across industries.

Calibration is an essential step in every precision noise measurement in order to achieve reliable and repeatable test results. So if it is important to you to ensure repeatable measurements, make sure to add the 42AG calibrator from GRAS to your solution.
