Extech RPM250W

Laser Tachometer with Connectivity to ExView® App

The Extech RPM250W is a compact Laser Tachometer with Bluetooth® connectivity, which allows building and maintenance professionals to view and share revolutions per minute (RPM) data of rotating objects directly from a mobile device using the free ExView® app. With the capability to capture data, display trends, set visual and audio alarms, and send reports, users can gain deeper insights on equipment health.

View data on both the large backlit LCD display and from iOS® or Android™ mobile devices using the ExView app via Bluetooth.

Take non-contact RPM measurements of rotating objects up to 500 mm (1.64 ft) and count up to 99,000; freeze the display with ‘data hold’ feature.

Export .CSV data; create and send PDF reports including photos of the measurement location taken with a connected smartphone or tablet camera.
