REED Instruments K4010-NIST TACHOMETER, PHOTO/CONTACT, 99,999 RPM/19,999 RPM W/NIST CERT

REED Instruments K4010-NIST TACHOMETER, PHOTO/CONTACT, 99,999 RPM/19,999 RPM W/NIST CERT 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 K4010 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 K4010 uses visible light for non-contact measurements to read up to 12" (300mm) from any target. The K4010 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 [custom1] REED K4010 Specifications RPM Range (Contact) 0.5 to 19,999  RPM Range (Photo) 5 to 99,999 Surface Speed Range  0.05 to 1,999.9 m/min   0.2 to 6,560 ft/min Resolution Photo: 0.1 RPM (‰¤999.9) / 1 RPM (>1000)Contact: 0.1 RPM (‰¤999.9) / 1 RPM (>1000)Surface: 0.1 m/min (‰¤99.99) / 0.1 ft/min (‰¤99.99) / 1 ft/min (>1000) Basic Accuracy ±(0.05% + 1 dgt.)
