Spesifikasi :

• Dimension 268 x 68 x 29 mm ( 10.6 x 2.7 x 1.1 inch).
• Display 52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits.
• Function dB (A & C frequency weighting), Time weighting(Fast, Slow), Hold, Memory ( max. & min. ), Peak hold, AC & RS232 output.
• Measurement Range 30 - 130 dB.
• Resolution 0.1 dB.
• Accuracy (23 5 ?) Frequency weighting meet IEC 61672 type 2, calibrating input signal on 94 dB(31.5 Hz to 8 kHz)
• Frequency Weighting Network Characteristics of A & C.
• A weighting - The characteristic is simulated as "Human Ear Listing" response. Typical, if making the environmental sound level measurement, always select to A weighting.
• C weighting - The characteristic is near the "FLAT" response. Typical, it is suitable for checking the noise of machinery (Q.C. check) & knowing the sound pressure level of the tested equipment.
• Frequency 31.5 Hz to 8,000 Hz.
• Calibrator B & K (Bruel & kjaer), multi-fuction acoustic calibrator.
• Microphone Electric condenser microphone.
• Size of microphone 1/2 inch standard size.
