LUTRON DS-2013SD Noise Dosimeter
Made in Taiwan
Measurement Type
SPL : Sound pressure level
Dose:test noise exposure
* Personal sound exposure meet IEC 61252
* Frequency and Time weighting are designed to meet IEC 61672 class 2.
* A & C weighting networks comply with standards.
* LCD is dot-matrix with backlight and easy reading.
* Combination Dose meter, Data-logger and Sound level meter.
* 0.5″ standard microphone head.
* Time weighting (Fast & Slow) dynamic characteristic modes.
* Build External calibration VR.
* User-defined measurement configurations. Selectable Criterion Level,
* Exchange Rate, Threshold, Frequency Weighting, and Response Time setting.
* Condenser microphone for high accuracy & long-term stability.
* Memory function to store the Max. & Min. value.
* Hold functions.
Measurement range
SPL:Auto 30 – 130 dB
Dose:70~130dB
Resolution 0.1 dB.
Accuracy (23 ± 5 )℃ : Characteristics of ” A ” frequency weighting network meet IEC 61672 class 2.
Under 94 dB input signal, the accuracy are :
31.5 Hz ± 3.5 dB
63 Hz ± 2.5 dB
125 Hz ± 2.0 dB
250 Hz ± 1.9 dB
500 Hz ± 1.9 dB
1 K Hz ± 1.4 dB
2 K Hz ± 2.6 dB
4 K Hz ± 3.6 dB
8 K Hz ± 5.6 dB
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.
Time weighting
Fast – t = 125 ms
* “Fast” range is simulated the human ear response time weighting.
Slow – t = 1 s
* “Slow” range is easy to get the average values of vibration sound level.
Over Indication Show ” – – – – “.
Memory Recall Maximum & Minimum value.
Sampling time of Display : approx. 1 second.
Power off : Auto shut off saves battery life or manual off by push button.
Operating temperature : 0 to 50 .℃
Operating Humidity: Less than 85% R.H.
