Fast and Easy Calibration: The Sound Level Calibrator is a convenient tool for quickly and easily calibrating sound level meters, microphones, and sound measuring systems. It ensures accuracy and reliability for various types of sound instruments. Accurate and Stable Performance: This calibrator utilizes solid-state integrated circuitry, providing accurate and stable performance. It meets IEC942 Class I standards. Versatile Applications: The calibrator is suitable for sensitivity calibration of microphones and can be used in both acoustics field and laboratory settings. It offers flexibility and precision in sound measurement. Standard Levels and Frequencies: It generates standard levels and frequencies, with sound pressure levels of 94 dB and 114 dB. The calibrator ensures high accuracy with a deviation of only ±0.3 dB. Convenient and Portable: The calibrator is battery-operated and comes with an instruction manual and battery included. Its compact dimensions of 48mm x 48mm x 138mm (5.43 x 1.89 x 1.89 inch) and lightweight design of 250g make it easy to carry and use in various environments. The calibrator generates these fixed sound level signals for calibration of sound level meters. This model works with any digital sound level meter. The unit ships with a ½" adaptor installed to accommodate sound meters and microphones with 1" or 1/2" microphone. Features To correct for atmospheric pressure in areas of high altitude the transducer diaphragm It has two output levels of 94 dB and 114 dB. Calibrated to produce 94dB at sea level. For each 2000ft of elevation sea ND-9 produce s 0.1dB less than the 94dB rating. Specifications Output Sound Level: 94db & 114db Accuracy: ±0.3db(20°C, 760mm Hg) Frequency: 1000±0.1%Hz (allows calibration with A,B,C or D weighting networks or linear) Temp. range: - 10~50°C (14~122 °F) Storage (with battery removed) -40~65°C (-40 ~ 149 °F) Extremely low influence of static pressure Temp.coefficient : 0 ~ 0.01dB/°C Power Supply: 9v Battery Battery life approx.100 hours Package Size: 17cm x 9cm x 6cm Package Weight: 0.39kg Set Includes 1 x Sound Level Meters Calibrator 1 x 9V Battery installed (FREE) 1 x English Instruction Manual Standard factory packaging box
