Microphone Calibrator

Description

94 and 114dB sound level meter precision calibrator with output frequency of 1000 ±1Hz. These have an LCD display which shows the selected dB level.

• Fits ½ inch and 1 inch microphones (includes ½ inch adapter)
• Low distortion output
• Easy one-handed operation with low battery indicator
• Every calibrator is tested by Studio Six Digital and verified to meet +/- 0.1dB at 94 and 114dB
• Includes AAA batteries

Specifications

• Sound Pressure Level: 94dB & 114dB
• Accuracy: ±0.3dB (20°C, 760mm Hg)
• Frequency: 1000±1 Hz allows calibration with A,B,C or D weighting networks or linear
• Microphone Size: 1″ and 1/2″ microphones
• Temperature Coefficient: 0~0.01 dB/°C
• Standard: IEC60942 (IEC942) Class 1
• Altitude Effects: Approximately decrease 0.1dB per 2000 ft increase in altitude from sea level to 12,000 ft elevation, or comparable atmospheric pressure change (approximately every 50mm of Hg decrease)
• Operating Temperature: -10~50°C
• Storage Temperature: -40~65°C(batteries removed)
• Size: 137 x x51 x 51mm
