GAOTek Sound Level Calibrator for Sound Level Meter

Description

Overview

GAOTek Sound Level Calibrator for Sound Level Meters is a highly accurate and reliable instrument designed specifically for calibrating sound level meters. It ensures precise calibration results and conforms to industry standards. With an adjustable sound pressure level range of 94 dB or 114 dB, it provides flexibility for various calibration needs. The calibrator generates stable and uniform sound signals, allowing users to verify and adjust the accuracy of their sound level meters. It is an essential tool for professionals in fields such as environmental monitoring, occupational safety, and sound engineering, ensuring the consistent and accurate measurement of sound levels.

Key Features

• Outputs two sound pressure levels: 94 dB and 114 dB at 1 kHz.
• Fits 1 in and 0.5 in microphones: Includes a ⅛ in adapter for 0.5 in microphones.
• Low battery indicator: Green LED indicator for operation, red LED indicator for low battery.
• Dimensions: 4.44 in x 2.48 in x 1.73 in (113 mm x 63 mm x 44 mm)
• Weight: Approx. 0.37 lb (170 g)
• The accuracy of this is ± 0.5 dB under understated reference environment conditions. This means that the output sound pressure level of the calibrator is accurate to within 0.5dB when the ambient temperature is 73 ℉ (23 ℃), the static pressure is 103 Hpa, and the relative humidity is 50 %.
• It is easy to use. Simply turn it on, select the desired output sound pressure level, and place the calibrator over the sound level microphone. The sound level meter will then automatically calibrate itself to the output of the calibrator.
• It fits both 1 in and 0.5 in microphones. A ⅛ in adapter is included for use with 0.5 in microphones.
• It has a low battery indicator. The green LED indicator will turn on when the calibrator is operating properly. The red LED indicator will turn on when the battery is low.
