Selection Guide

Accurate sound level measurement depends not only on the instrument, but also on frequency weighting, time weighting, microphone position, measurement distance, environmental conditions, and operating method. This article explains the essential steps for using a sound level meter correctly, from pre-measurement checks and parameter settings to field measurement, data recording, and common mistakes.

Sound pressure levels vary widely, from sounds near the threshold of hearing to conversation, traffic, machinery, and extremely loud sources. This guide provides a practical decibel level reference chart and explains how to interpret common dB values. It also covers the effects of frequency weighting, measurement distance, environmental conditions, and exposure duration on noise measurements.

A digital sound level meter is a professional instrument used to measure sound intensity in various environments. This article explains the key components of a digital sound level meter, including the microphone sensor, signal processing system, display module, control interface, and power system, helping users better understand its structure and functions.

Sound level meters are essential instruments for measuring sound pressure levels. Depending on measurement accuracy, functionality, and application requirements, they range from basic handheld meters to integrating sound level meters, data-logging instruments, professional sound analyzers, and permanent noise monitoring systems. This guide explains the main types, their functions, typical applications, and key factors to consider when selecting an instrument.

A digital sound level meter converts variations in air pressure into electrical signals through a microphone. The signals are then amplified, frequency-weighted, time-weighted, digitized, and processed to calculate sound pressure level in decibels. This article explains the complete measurement process, including A/C frequency weighting, FAST/SLOW time weighting, and key factors affecting measurement results.

Decibel (dB) is the most widely used unit for describing sound levels. This article explains the concept of decibel, its relationship with sound pressure level, dB(A) weighting, and practical applications in noise measurement to help users better understand sound measurement principles.

A digital sound level meter is a professional instrument used to measure sound pressure levels, typically displayed in decibels (dB). This guide explains how digital sound level meters work, their main components, A/C frequency weighting, FAST/SLOW time weighting, key specifications, common applications, selection criteria, and proper measurement practices.

A digital lux meter is an important measurement instrument for evaluating illumination levels in lighting engineering, industrial inspection, building assessment, laboratories, and environmental monitoring. Proper maintenance and care help maintain measurement accuracy, improve instrument reliability, and extend service life. This article explains essential maintenance methods, including sensor protection, cleaning, storage, calibration, and daily operation recommendations.

A digital lux meter is an essential instrument for measuring illuminance in environments such as buildings, industrial facilities, offices, schools, hospitals, and laboratories. Correct operation methods help reduce measurement errors and improve data reliability. This article explains the proper usage methods and key precautions for digital lux meters.

Retail lighting plays an important role in product presentation, customer experience, visual comfort, and energy efficiency. This article introduces recommended illuminance levels for shopping malls and retail stores, explains lighting requirements for different commercial areas, and provides practical guidance on retail lighting design and on-site illuminance measurement.

Hospital lighting requirements vary significantly depending on the function of each space. Examination rooms, laboratories, pharmacies, patient rooms, nurse stations, waiting areas, corridors, and surgical areas all require different illuminance levels. This article provides practical hospital lighting reference values and explains how to measure illuminance correctly using a digital lux meter.

Warehouse lighting directly affects storage efficiency, label recognition, picking accuracy, and operational safety. However, there is no single illuminance value suitable for every warehouse area. Different zones have different visual tasks and therefore require different lighting levels. This article provides a concise guide to common warehouse illuminance standards, measurement methods, and practical evaluation points to help users better assess and improve warehouse lighting conditions.
