TS-501B Decibel Meter
TS-301 Anemometer
TS-630 Moisture Meter
The TS-501B sound level meter, with weighting, ranges from 30 to 130 dB. In a quiet environment, it reads between 30 and 45 dB.
Precision Microphone
The microphone of decibel meter converts the sound signal to an equivalent electrical signal.
Protective Film
With a screen protector to avoid scratches on the screen of the decibel meter during transportation.
Anti-slip Design
The durable plastic anti-slip strips on both sides of the noise meter TS-501B, increase friction.
Easy to Carry
The velvet cloth pouch with bungee cord is easy to store and protect SLP meter TS-501B.
Low Battery Indication
The SPL meter TS-501B has a low battery reminder function to know when the battery needs to be replaced.
Data Hold Function
The TS-501B sound level meter has a data hold function that can freeze readings.
Max/Min Measurement
The TS-501B decibel meter can record the maximum and minimum values of sound over a period of time.
Fast/Slow Time Weighted
Fast weighting(125 ms) is approximate to the ears’ time response.
Slow weighting(1 s) is used to indicate the average level of fluctuating noise.
Why doesn’t the TS-501B show 0 dB in a quiet environment?
The TS-501B measures from 30–130 dB and does not start at 0 dB. When sound levels are below 30 dB, it displays “UL” (Under Limit). In a quiet environment, it reads between 30 and 45 dB.
What scenarios are sound level meters usually used for?
Sound level meters are often used for measuring community or environmental noise; Use for measuring noise produced by machinery in industries; Use for calibrating audio equipment at concerts or for personal reasons.
What is the difference between A Frequency Weighting and C Frequency Weighting?
The A-weighting adjusts the sound pressure level readings to reflect the sensitivity of the human ear and is used for hearing damage risk measurements.
The C-Weighting is used for Peak measurements and also in some entertainment noise measurements.
What is the difference MAX/MIN Value between A-Weighting and C-Weighting?
MAX/MIN Value of A-Weighting is Lmax/Lmin (the highest and lowest values measured by the sound level meter over a given period of time.);
MAX/MIN Value of C-Weighting is Lpeak (the max/min value of the absolute instantaneous sound pressure).
Decibel Levels: Typical Scenarios
30-40 dB: Library, bedroom.
50-60 dB: Restaurant, café.
70-80 dB: City roads, factory machinery.
90-100 dB: Rock concert.
110-130 dB: Jet airplanes, front row at a concert.
