CRY2110 Noise sensor

CRY2110 Noise sensor is a new type of noise test equipment developed by CRY Sound for industrial applications. Its product performance complies with such standards as IEC61672 (Class 2) and GB/T3785 (Type 2).

The sensor is small in size and its stainless steel case is robust and corrosion-resistant. It is equipped with precision measurement microphone, integrated preamplifier, high precision ADC and high speed DSP processor. Its excellent hardware design provides 110 dB dynamic range. With excellent performance, it can measure the environmental noises as low as 25 dBA.
