BENETECH GT1355A / GT1355B

Sound & Noise Decibel Level Meter

A/C Weighted db Meter

The decibel meter employs a condenser microphone to measure sound levels ranging from 30 to 130 dB (A) / 35 to 130 dB (C), with an accuracy of ±1.5 dB, and covers frequencies from 31.5 Hz to 8,500 Hz.

Easy to Read

The LCD backlight screen of the sound level meter visually displays the noise data changes Max value. You can switch between fast/slow time weighting or freeze the current reading as needed. When the volume exceeds the set alarm value, the indicator light and screen of the sound level meter will change color to alert you according to the noise level.

Real-Time Monitoring & Recording

The sound pressure level (SPL) meter is capable of storing up to 31,000 sets of data and import the data saved to a PC via the USB port for real-time data sampling and analysis, data downloading, printing charts/data reading, and deletion. Additionally, you can set the date, configure an automatic shutdown time, and low battery indicator to remind you when it's necessary to recharge.

Lightweight & Long-Lasting

This noise level meter features non-slip rubber grip and weighs just 4.23 ounces, making it convenient to carry around. The decibel meter boasts 1/4-inch mounting threads on its back for attachment to a stand, and can stay in standby mode for up to 8 hours after a 1.5-hour charge for extended monitoring.
