Model MF-2 Combination Hand Tachometer

Our newest precision tachometer with NIST Certification

Using the latest in microprocessor technology, the MF-2 can be used as a non-contact or a contact tachometer simply by adding or removing the supplied slide-in adapter. It measures RPM from 1 to 99,999 as well as FPM, mPM and IPM. It can also measure the length of moving surfaces in feet, meters or inches. In the non-contact mode, RPM is measured by means of a visible beam of light. The meter can be held up to 14" away from a small piece of reflective tape attached to the rotating part. In the contact mode, one of the contact adapters is held against the rotating element. The bright LCD display has a low battery indicator, memory indicators, on-target indicator and unit of measure indicators. Accuracy is 0.02% and built in memory stores maximum, minimum and last reading results. The instrument features rugged construction and comes with a two year warranty. Includes case and accessories. N.I.S.T. certification is included at no extra cost.

DH-4M Microprocessor Controlled Digital Hand Tachometer

Bright LED Display Multi-mode speed selection
N.I.S.T. Calibration Included Wide Speed Range

In addition to measuring rotational linear and surface speeds, our new model DH-4M now measures total length in meters , centimeters, inches, feet and yards. Other new features include longer lasting battery life with fewer batteries and increased memory. Manufactured to ISO 9001 standards, the rugged DH-4M hand tachometer offers the latest in microprocessor technology to provide the utmost in accuracy and versatility. a die cast aluminum housing insures durability and protection.

WIDE ROTATIONAL SPEED RANGE
Measures from 0.1 to 25,000RPM with a floating decimal for automatic indication in tenths from 0.1 to 999.9

MULTI-MODE ROTATIONAL SPEED SELECTION
Per Minute: RPM, FPM, mPM, YPM, IPM
Per Hour: RPH, FPH, mPH, YPH, MPH

LARGE MEMORY CAPACITY
Provides last reading maximum, minimum, and 10 additional speed readings- automatically or by selection.

COMPLETE ACCESSORIES
Comes with carrying case, master wheel, 2 cone adapters, 1 funnel adaptor, 3 1/2" extension shaft, batteries.

OVERSPEED PROTECTION
A single-range low inertia drive system uses optical loading. The result is minimum shaft loading and elimination of the possibility of instrument damage because of over speed on too low a range setting.

N.I.S.T. CERTIFICATION INCLUDED

ALSO AVAILABLE: MODEL DH4-LM WITH LCD DISPLAY AND 65 HOUR BATTERY LIFE
