Product Introduction
The HS14423B is a 1/2-inch (Φ12.7mm) test condenser microphone designed for acoustic measurement instruments. With a frequency range of 20Hz-12.5kHz and sensitivity of 25mV/Pa (±2dB), it delivers reliable performance in environmental noise monitoring and industrial equipment analysis. The zero-polarization-voltage design eliminates external power requirements, while the rugged metal housing ensures durability in field applications. Compatible with HS5633/5618/6288 series sound level meters, this microphone features a 20pF static capacitance and 10-100pF variable range for stable signal output across 15-142dB dynamic range. 61722
Key Features
This free-field type microphone exhibits flat frequency response (±0.5dB from 200Hz-5kHz) with true RMS detection capability. The integrated preamplifier provides impedance matching for noise-resistant signal transmission. Its threaded mounting interface allows secure attachment to standard sound level meters, and the detachable windscreen minimizes airflow interference during outdoor measurements. The product is recommended for use in temperature ranges of -10°C to 50°C with relative humidity below 90%. 51318
Typical Applications
Ideal for occupational health surveys, product quality control, and environmental compliance testing. Typical use cases include factory noise mapping, HVAC system evaluation, and community noise studies. When paired with integrating sound level meters, it enables automated data logging of time-weighted averages and statistical noise levels. The compact form factor makes it suitable for handheld operation in tight spaces like vehicle cabins or machinery compartments. 4914
