Product Details

CaSTLe Integrating Sound Level Meter

The CaSTLe GA113 is a 20KHz integrated sound level meter and dosemeter. It provides necessary information for completing risk assessments such as integrated equivalent level (LEQ) measurement, personal sound exposure level (LEX or LEPd) measurement, DOSE%, projected DOSE%, and projected Lex functions sound pressure (Lp) to 0.1dB resolution. It can also easily specify the A and C frequency weighting along with slow and fast time constraints. It has an LCD backlight display.

Dosemeter Microphone Converts GA113 Sound Level Meter into a personal sound exposure meter (dosemeter). Includes Class 2 (Type 2) microphone. When fitted, meter complies with IEC 61252:1993

This instrument is supplied with a 1-year warranty and factory calibration from the date of manufacture. A free 3-year warranty extension is available subject to annual calibration being maintained.

For compliance with the Noise at Work regulations and relevant international standards, sound level meters should be calibrated before use and checked afterwards. See later in this section for GA607 acoustic calibrator (stock no. 479-2034). A kit case (KA010, stock no. 229-9454) for protecting your GA113 and GA60766 is also available.
