Traceable Tachometer with Red LED and Calibration

Digi-Sense, 98767-08, Traceable Relative Humidity Meter with Dew Point and Calibration98767-08 Includes Only:TachometerReflective tape (2 ft/0.6 m)1 x 9 V batteryNIST-traceable calibration certificate with data.Features:NIST-Traceable certificate from A2LA accredited (1750.01) calibration laboratoryObtain speed readings in 2 seconds; HOLD button freezes resultsRugged ABS-plastic housingThis handheld, point-and-shoot tachometer targets a rotating object and provides instant results - simply place a piece of reflective tape on the object to be measured. Speed readings are provided in 2 seconds over a range of 10 to 99,999 RPM. Tachometer powers off automatically after 20 min of non-use.Compact tachometer fits easily in your hand, pocket, or toolbox. Ideal for measuring speed on centrifuges, pumps, rollers, shafts, gears, motors, and moving surfaces.Traceable Products have an individually-numbered Traceable Certificate provided with each unit, that assures accuracy from ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.
