Features:

Frequency weighting networks are designed to meet IEC 651 type 2 standards
A and C weighting networks conform to standards.
Fast and Slow dynamic characteristic modes.
Built-in adj. VR is available for easy calibration.
Uses a high quality condenser microphone for high accuracy and long term stability.
Max. Hold function for stored maximum value on display.
Warning indicators for over and under load.

Specifications:

Display 18 mm (0.7") LCD (Liquid Crystal Display), 3 1/2 digits
Function dB (A & C frequency weighting), Time weighting(Fast, Slow), Max. hold, AC & DC output.
Measurement range 3 ranges, 30 to 130 dB, input signal only
Resolution 0.1 dB
Accuracy Frequency weighting meet IEC 651 type 2, calibrating input signal on 94 dB(31.5 Hz to 8 kHz)
  31.5 Hz - ± 3 dB, 63 Hz - ± 2 dB, 125 Hz - ± 1.5 dB
  250 Hz - ± 1.5 dB, 500 Hz - ± 1.5 dB, 1 kHz - ± 1.5 dB
  2 kHz - ± 2 dB, 4 kHz - ± 3 dB, 8 kHz - ± 5 dB
Frequency weighting A weighting - The characteristic is simulated as "Human Ear Listing" response.
  Typical if making environment sound level measurement
  C weighting - The characteristic is near the "FLAT" response
  Suited for shecking noise of machinery
Frequency  31.5 Hz to 8,000 Hz.
Calibrator B & K (Bruel & kjaer),multi-fuction acoustic calibrator, model : 4226
Range selector 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step
Time weighting Fast - t= 200 ms, Slow - t = 500 ms,
  "Fast" range is simulated the human ear response time weighting.
  "Slow" range is easy to get the average values of vibration sound level
Output signal AC output - AC 0.5 Vrms corresponding to each range step.
  DC output - DC 0.3 to 1.3 VDC, 10 mV per dB.
Operating Temp. 0 to 50 Celsius ( 32 to 122 Fahrenheit ).
Operating Humidity Less than 80% RH
Power Supply 006P DC 9V battery(heavy duty type).
Dimension 205 x 80 x 35 mm ( 8.1 x 3.2 x 1.4 inch).
