| Description
 The Sanwa SE300 is a non-contact digital rotational tachometer designed to measure the speed of rotating objects, such as motors and fans, without making physical contact. This is achieved by using a laser beam to detect a reflective sticker placed on the rotating surface.  | 
| Key Features
 Non-contact measurement: Measures rotation from a safe distance of 50 to 500 mm, using a laser and a reflective sticker. Wide measurement range: Captures rotational speeds from 30.0 to 99,999 RPM.. Data tracking: The unit includes a MAX/MIN hold function to display the highest and lowest measured values. It also has a data hold function to freeze the current reading on the screen. Ergonomic design: Built with an easy-to-hold body for stable and comfortable operation during measurements. Flexible setup: Can be mounted on a tripod for fixed, hands-free measurements. Backlit display: The LCD display is backlit for clear visibility in dimly lit environments. Auto power-off: Includes a function to automatically shut off after approximately 2 minutes of inactivity to save battery power. This feature can be disabled. Optional contact measurement: With the addition of the optional ENC-3 Contact Measurement Adapter (sold separately), the device can also perform contact-based measurements. Multiple measurement modes: The SE300 can measure more than just revolutions per minute (rpm), including: 1. rpm. Revolutions per second 2. m/min and m/s: Peripheral speed (meters per minute and meters per second) 3. ms: Interval time 4. Count: Cumulative rotation count  |
