REED Instruments R8050-NIST sound level meter is ideal for acoustic measurements. It measures industrial machinery / equipment and construction sites' noise levels to ensure safe working conditions.
Working Mechanism:
- Turn On the meter and press the time weighting button to select the desired response time.
- Set the response to FAST (125 ms) if the sound source has only short bursts.
- Select SLOW (1 s) for average sound level measurement.
- Press the frequency weighting button to adjust the frequency.
- Press the 'Hi/Lo' button to select the appropriate range.
- If the display flashes the OVER icon (after setting the range), adjust the range again.
- Hold the instrument in one hand (away from the body) or place it on a tripod for long-term monitoring.
- Point the microphone in the sound direction to take a measurement.
Features:
- REED Instruments R8050-NIST sound level meter has a microphone windscreen ball for sound buffeting.
- It has an auto shut-off feature that turns off the meter if left idle for more than 15 minutes.
- This meter has a backlit 4-digit LCD for easy observations.
- It has dual-range (high & low) measurement ability for fast (125 ms) and slow (1 s) time weighting.
- This meter features a low battery indicator that notifies users to replace the battery.

Frequently Asked Questions:
Q. How to view only the maximum sound levels during measurement?
A.
- Press the 'MAX/HOLD' button to display the maximum recorded values.
- In this mode, the meter only updates when it discovers a reading higher than the current maximum reading.
Q. How to hold a specific reading in this sound level meter?
A. Press and hold the 'MAX/HOLD' button until both the 'MAX' & 'HOLD' icons appear. This act will freeze the display's current reading.
Q. How to calibrate REED Instruments R8050-NIST sound level meter?
A.
- Open the battery compartment and locate the two calibration potentiometers behind the battery.
- Turn On the meter and select 'C' weighting & 'FAST' response mode.
- Place the microphone into the calibrator.
- Set the calibrator to output 94 dB.
- Select the LOW range and adjust the 'C (Lo)' potentiometer for a display of 94.0 dB.
- Select the HIGH range and adjust the 'C (HI)' potentiometer for a display of 94.0 dB.
- Set the calibrator to output 114 dB and verify the measurement.
Q. What is the sound measurement range of this meter?
A. REED Instruments R8050-NIST sound level meter measures noise within the range of 30 to 130 dB with an accuracy of +/-1.4 dB.
