HH100 Multi-Function Digital Tachometer • • • • • • • • Measures from 1 RPM to 99,999 RPM. Accuracy of 0.02% with a resolution of 0.01 RPM. Contact or non-contact measuring in user units. Measure RPM, surface speed and length. Rugged and lightweight design. NIST certification included. Built-in memory function. 2-year warranty. Product Information Description The Electro-Sensors, Inc. HH100 Combination Hand-Held Digital Tachometer combines the best features of both contact and non-contact models to accurately measure RPM, surface speed and length. When using the non-contact mode, rotational speed (RPM) is measured using a visible beam of light. The HH100 can be up to 14 inches away from the small piece of reflective tape that is affixed to the rotating element. In the contact operating mode, the speed is sensed by directly contacting the rotating device using one of the contact adapters supplied with the instrument. In other applications where surface or linear speeds are to be measured, the universal wheel is used for direct readout of feet/min, meters/min or inches/min, as selected by the end user. The HH100 can also be used to measure the accumulated total of continuously running material such as paper, wire being wound on a spool or to check the calibration of on-line counters and totalizers. The HH100's rugged construction, portability and outstanding features make it an ideal choice for maintenance personnel, machine operators or others in a wide variety of machinery and material handling applications. The HH100 uses the latest microprocessor technology and is backed by an industry-leading, two-year warranty. Applications • HH100 LCD Display • HH100 Memory Indicators Contact RPM — Used to measure the speed of rotating motors, shafts, pulleys, gears and more. Low Battery Indicator On-Target Indicator Contact Indicator Units of Measure Non-Contact RPM — Used when contact measurement is not possible due to access, space restrictions or safety concerns. Linear Speed and Length — Used to measure the linear speed or length of moving surfaces, such as conveyor belts, printed materials, webs of fabric or paper and more. 6111 Blue Circle Drive Minnetonka, MN 55343 Phone: 952-930-0100 Fax: 952-930-0130 ISO9001:2000 Certified Units of Measure Indicators — shows the user-selected units of measure.
