Reed R7140-NIST Combination Contact / Laser Photo Tachometer
(Replaced Reed K4010-NIST)
Reed R7140-NIST Datasheet (PDF)
Dual function tachometer features the ability to measure RPM with non-contact (visible light) and contact (ft/min / m/min) measurements quickly and accurately.
REED R7140 Offers
This tachometer features both the ability to measure RPM (revolutions per minute) in rotational equipment and surface speed m/min (meter per minute) / ft/min (feet per minute) with included contact adapters. The R7140 uses visible light for non-contact measurements to read up to 12″ (300mm) from any target. The R7140 features a durable ABS plastic housing to assure years of maintenance free performance.
Features
- Dual function unit with both contact and non-contact capabilities
- Provides fast and accurate RPM measurements of rotating objects and surface speed measurements m/min (meter per min) and ft/min (feet per min)
- Internal memory holds last reading for 5 mins and recalls min/max and last value
- LCD Display reverses depending on measurement mode
