Sound Meter Calibrator with 94dB and 114dB Output Levels

The sound meter calibrator generates fixed sound level signals specifically designed for calibrating sound level meters. This model is universally compatible with any digital sound level meter and is pre-installed with a ½” adaptor to suit both 1″ and ½” microphones. It utilises solid-state integrated circuitry for accurate and stable performance. **Key Features:** – **Output Levels:** Delivers 94 dB and 114 dB, calibrated to produce 94dB at sea level. Note that for each 2000 feet of elevation, it produces 0.1dB less than the 94dB rating. – **Accuracy:** ±0.3dB at 20°C and 760mm Hg, with a frequency of 1000±0.1%Hz, allowing for calibration with A, B, C or D weighting networks. – **Temperature Range:** Operational from -10°C to 50°C (14°F to 122°F), with safe storage (battery removed) from -40°C to 65°C (-40°F to 149°F). **Specifications:** – **Power Supply:** Operates on a 9V battery (included), with a battery life of approximately 100 hours. – **Dimensions:** Measures 48mm x 48mm x 138mm (5.43 x 1.89 x 1.89 inches). – **Package Size:** Comes in a package measuring 17cm x 9cm x 6cm and weighs 0.39kg. **Included Items:** – 1 x Sound Level Meter Calibrator – 1 x Installed 9V Battery – 1 x English Instruction Manual This calibrator is widely applicable for monitoring and testing noise levels in domestic spaces, laboratories, offices, theatres, and audio systems, allowing for appropriate sound adjustments critically. It is ideal for microphone sensitivity calibration and suitable for both field and laboratory use.
