REED INSTRUMENTS R8050-KIT Sound Level Meter And Calibrator Kit, 35 To 135 dB, 31.5Hz To 8kHz

REED Instruments R8050-KIT sound level meter kit consist of a sound level meter, calibrator and a hard carrying case. It is ideal for measuring industrial machinery / equipment and construction sites' noise levels to ensure safe working conditions.

Working Mechanism:

Sound level meter

• Turn On the meter and press the time weighting button to select the desired responsetime.
• 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.

Sound level calibrator

• Insert the microphone into the calibrator's microphone cavity.
• Depending on your preference, move the range switch to either the 94 or 114 dB setting.
• Once the switch turns on, the calibrator starts to produce a signal.
• Read the sound level meter's value.
• Depending on the calibrator's signal level, the sound level meter should display a reading of 94 or 114 dB.
• Adjust the sound level calibrator in accordance with the sound level meter if the calibrator's signal does not match the calibrator.

Features:

• REED Instruments R8050-KIT sound level meter kit has a microphone windscreen ball to eliminate wind noise for accurate measurements.
• The meter has an auto shut-off feature that turns it off if left idle for more than 15 minutes and a backlit 4-digit LCD for easy observations.
• This kit's meter features a low battery indicator that notifies users to replace the battery and has dual-range (high & low) measurement ability for fast (125 ms) & slow (1 s) time weighting.
• The sound level calibrator generates a stable acoustic signal at a controlled frequency and amplitude to verify the accuracy of your sound level meter.
• The hard carrying case is ideal for storing and transporting the sound level meter and calibrator.

Compatible Accessories:

• REED Instruments R1500 Lightweight Tripod: This height-adjustable tripod is suitable to mount the sound level meter for acoustic measurements over long durations.

Standards and Approvals:

• CE
• IEC
• ANSI

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. What is the accuracy of this kit's calibrator?

A. +/-0.05%.

Q. What are the ideal operating conditions for this kit's sound level meter and calibrator?

A.

• Temperature - 32 to 122 degrees F
• Relative humidity - 0 to 85%
