Decibel Meter Digital Sound Meter with Backlight LCD Display Portable SPL Meter with A/C Weighted Range 30dB to 130dB Fast/Slow Time Response No

Wide Ranges, High Accurate: The Noise Meter ftures a high-sensitivity, high- condenser microphone, capable of msuring noise s from 30 to 130 dB, high accuracy of +-1.5 dB, frequency from 31.5Hz to 8.5KHz. A/C Weighted Msurement: The A weighted simulates the frequency characteristics of low- human r noise, which is suitable for the detection of ambient noise. The C weighted simulates the frequency properties of high- noises of the human r, which are suitable for the sound pressure analysis of NaMachine motors and NaMachines. Fast and Slow Msurement: The decibel meter has the function of converting the fast and slow response rate. The rate uses a time constant of 0.125s/time for general environmental msurement. The slow response rate uses a 1s/time constant, which is used for environmental msurements with relatively large changes in noise s. This sound meter is a quality sound msuring instrument with a set of functions that make it useful for a variety of professionals with a backlight LCD display, 130dB full scale msurement capability, both A and C-weighting msurement support, and pk functions, it can help make many msurement tasks sier.

Backlight Display: White LCD backlight display, the rding effect is clrer in dark places. When the battery is low, the LCD display will display a low voltage , indicating that the power is low at this point and the battery needs to be replaced. Widely Application: This noise msure device is a grt tool for checking, monitoring or controlling and test the sound of any environments. It is widely applicable for , families, business, studies, industrial and etc. Specifications: Model: TL-205 Material: ABS Designed According to Standards: IEC651 (Type 2) and ANSI S1.4 (Type 2) Calibration Sound Source: 94dB 1KHz Msurement Range: 30-130dB Accuracy: +-1.5dB (reference sound pressure standard, 94dB 1KHz) Frequency Response: 31.5Hz-8.5KHz Resolution: 0.1dB Msurement Weighting: A or C weighting Bar Graph Display: 2dB/Bar graph increment Meter Response Time: Fast (125 milliseconds)
