TopTes TS-501A Decibel Meter with A‑Weighting, 2.25″ LCD, Max/Min

Description

Product Overview

The TOPTES TS-501A is a handheld decibel meter designed for professionals and enthusiasts who require accurate sound pressure level (SPL) measurements in a variety of environments. Built around a high‑precision condenser microphone, the device applies A‑weighting to reflect the human ear’s response to noise, delivering readings from 30 dB to 130 dB with a tolerance of ±1.5 dB. The 2.25‑inch LCD screen is backlit, providing clear visibility in bright daylight or low‑light conditions. Key specifications include dimensions of 2.17 × 1.02 × 5.51 inches, a weight of 9.88 oz, and a model number TS‑501A. Power is supplied by three AAA batteries (included) and the unit features an automatic power‑off and low‑battery indicator to extend operational life.

Usage

This meter excels in settings where sound monitoring is critical. Construction sites can use it to verify compliance with occupational noise regulations, while musicians and sound engineers rely on it for venue acoustics and equipment tuning. Safety officers employ the device during inspections of machinery, HVAC systems, and public events to protect workers and attendees from hazardous noise exposure. Its compact size and carry case make it convenient for field technicians, wildlife researchers, and hobbyists measuring environmental noise or testing home theater setups.

FAQ

How often does the meter need calibration?

The TS‑501A is factory calibrated and remains accurate for up to two years under normal use. Re‑calibration is recommended if the device is dropped or exposed to extreme conditions.

Can the meter measure impulse noises?

Yes, the fast response time of the condenser microphone allows the TS‑501A to capture short‑duration impulse sounds, making it suitable for gunfire, hammer strikes, or sudden equipment noise.

What is the battery life on a full set of AAA batteries?

With typical usage, the meter operates for approximately 200 hours before the low‑battery indicator appears. The automatic power‑off further conserves energy when the device is idle.

Is the device compatible with noise‑dosimetry software?

The TS‑501A stores max/min values internally, but it does not have data export capabilities. For detailed logging, users can manually record readings or pair the meter with a compatible external logger.

Does the meter work in extreme temperatures?

The unit is rated for operation between -10 °C and 50 °C (14 °F‑122 °F). Performance may degrade outside this range, so store the device in a temperate environment for optimal accuracy.
