News 2020- Gefell stays innovative - despite Corona

MTG is currently presenting a wide range of new developments for acoustic applications in industry, R&D and environmental protection

Product news 2020 - examples:

1/2"Measurement Microphone MMS 212

with the newly developed ½" Measuring microphone capsules MKS 221Steel Edition or MKS 221 Rugged Design

1/2“Measurement Microphone MMS 212 for rugged environment

• free-field
• 3,5 Hz to 20 kHz
• 15 dBA to 139 dB
• IEPE (BNC)
• TEDS acc. IEEE 1451

The 1/2“ measurement microphone MMS 212 is very insensitive to extreme temperatures, moisture, dustand vibration.

This is achieved by a special design of protection grid,pressure compensation opening and plug connector.

The MMS 212 complies the IPrating IP 67 and can be calibrated with a standard 1/2“ sound calibrator.
An integrated power-on indicator permanently indicates correct function andensures reliable measurements.
