Product Description

Traceable is a leader in designing, manufacturing, and selling individually serialized, calibrated, and certified Traceable lab instruments. Our services extend to monitoring systems, reagents, and various precision tools that are to be used during critical, controlled, and accredited processes in the biopharmaceutical, healthcare, and laboratory industries.
Traceable products have an individually numbered Traceable Certificate that assures accuracy from our 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.


Item number 20250-26 includes contact converter, surface speed wheel, rpm contact adapter, large male rpm rubber cone, small male rpm rubber cone, female rpm rubber cone, reflective tape (23-5/8”, 60 cm), four set screws, carrying case, four AA batteries, and NIST-traceable calibration.
Measure from a distance up to 19-11/16” (50 cm) in photo tachometer mode, ensuring operator safety.
- Stores up to twenty last average measurements for additional flexibility
- Durable, lightweight ABS housing
Traceable Digital Contact/Photo Tachometer
Ensure your equipment is in optimal operating condition, eliminating costly repairs
This digital contact/photo tachometer is designed for quick and accurate rpm and surface speed measurements on fans, motors, turbines, gears, conveyors, rollers, shafts and cams, spindles, and more.
Easily configure the tachometer for either contact or photo (noncontact) measurements depending on your application requirements. Use the included adapters in contact mode for quickly taking measurements; take measurements from a distance when in photo mode for use on dangerous running equipment.
- Microprocessor-based design provides precision accuracy of ±0.05%
- Features include max, min, and values stored, auto-ranging, built-in memory recall of up to twenty last average measurements
- Easily view max, min and last value for interpretation
