The Hioki FT3405 and FT3406 are portable, contactless digital tachometers that use reflected visible spectrum light to measure the speed of a rotating object to which reflective tape has been affixed. The instruments can also be used as a contact-type tachometer by attaching the Z5003 Contact Adapter. Contactless performance ensures safety and peace of mind when measuring rotating objects that are recessed inside equipment or whose movement poses a hazard. Simply apply reflective tape to the object being measured, point the instrument at the tape, and press the button

The Extech RPM33 provides both contact (2 to 19,999 rpm) and non-contact (2 to 99,999 rpm) revolutions per minute measurements for enhanced versatility. Safely record laser-guided non contact RPM measurements from up to 500 mm (1.6 feet) away. The RPM33 displays on the large five-digit backlit LCD. Store and recall 10 data sets in memory with four parameters (measurement, max, min and average). The unit comes with contact wheel for linear surface speed 0 to 1999.9 meters/minute; 0.2 to 6560 feet/minute) or RPM measurements, 9-volt battery, reflective tape, carrying case, and user manual.
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.
The RPM10 is a combination tachometer which provides both contact and non-contact RPM measurements, making this device useful in virtually all applications. The RPM10 also features a built-in IR thermometer with laser pointer for measuring surface temperature from -4 to 600 degrees F (-20 to 315 degrees C), making it ideal for checking the operating temperature of motors, bearings and machinery. Complete with wheels for linear surface speed (0.2 to 6560 ft. /minute; 0.05 to 1999.9 m/minute) or RPM measurements, 4 AA batteries, 23 in. (0.6 m) reflective tape, carrying case, and user manual.
