A shotgun-type Directional Microphone that sharply captures targeted sounds.
It is ideal for simple sound source detection and removing background noise in abnormal sound detection.

sensor amplifier

SR-2210 2ch Sensor Amplifier
sensor amplifier
Features
This is a 2ch sensor amplifier for inputting the sensor of a constant current drive amplifier into analyzers and recorders such as DAT that do not support constant current amplifiers. It has a dual power supply system of battery operation/AC adapter (optional). It can be stacked and fixed, supporting multi-channel configurations.

Sound calibration

SC-2600
audio calibration device		 SC-2500A
audio calibration device		 SC-2120A
audio calibration device
Audio calibration No.1 Audio calibration No.2 Audio calibration No.3
Features
It is an acoustic calibration device that complies with JIS C 1515:2020 Class 1, with a nominal sound pressure level of 94 dB. By incorporating feedback control along with correction functions for static pressure and temperature, it generates stable sound. For high-precision measurements using the low-noise microphone MI-1282M10*, the use of this product is recommended. *An acoustic calibration device with a nominal sound pressure level of 94 dB is required for the acoustic calibration of the low-noise microphone.		 Features
It is an acoustic calibration device that complies with JIS C 1515:2020 Class 1, with a nominal sound pressure level of 114 dB. By performing feedback control internally, it generates stable sound. Due to the high sound pressure level of 114 dB, it is less affected by surrounding noise in environments such as factories and outdoors, allowing for calibration in actual measurement environments.		 Features
It is an acoustic calibration device that complies with JIS C 1515:2004 Class 2, with a nominal sound pressure level of 94 dB. It can also be used for simple operational checks. It adopts a dynamic speaker type, achieving a low price.
