  • Review
The HT-90C multifunctional sound level meter is a new generation of noise measurement instrument using digital signal processing technology. It has a large measurement range, stronger functions, lower power consumption, and a color LCD display. Three parallel (simultaneous) frequency weightings of A, C, and Z, and three parallel (simultaneous) time weighting of F, S, and I can measure multiple evaluation indicators simultaneously. Many analysis functions, statistics, integration, 1 / 1OCT, 1 / 3OCT, FFT and digital recording can be started synchronously or asynchronously. The instrument can be widely used in the fields of environmental protection, labor hygiene, industrial enterprises, scientific research and teaching, etc., to complete environmental noise measurement, sound power level measurement, machine equipment noise measurement and building acoustic measurement
