Description
Bently Nevada™ Scout™COMMTEST220 and COMMTEST240 are portable data analyzer solutions designed to monitor machinery in non-hazardous environments. These small form-factor, rugged devices take vibration recordings and upload the collected data for detailed analysis in System 1. This is a two-part solution. The COMMTEST data acquisition module uses Bluetooth to communicate with a wireless, industrial handheld device running the S1 Collector app. Vibration recordings are viewed and stored on the handheld device.The handheld runs the Android OSor Apple iOS, so you can also use it like any smartphone or tablet to take pictures and video, send text messages, check email, make phone calls, track your location, create SOS alerts, and run other enterprise apps.
