Laser Optical/Contact Tachometer

SKU: ADT-6236B


An optical/contact tachometer for measuring speeds of rotating objects in revolutions per minute. It also measures surface speeds in metres per minute or feet per minute. High accuracy is achieved by combining CPU, photoelectrical and laser techniques. The ergonomic design makes the instrument comfortable to use.

Calibration Options

A calibration service can be purchased for this unit. Once the Service has been performed a certificate of calibration is produced and dispatched with your order. Calibration Services are performed on receipt of your order and as such will delay shipping. Details and options are outlined below.

UKAS Calibration (Tachometer) Price
Issued at 5 points: 100, 500, 1000, 5000 & 10,000 RPM
Additional points: From 100 to 50,000 RPM
£15.00 per point

A UKAS calibration can also be considered traceable. The difference between the two is that UKAS calibrations are carried out under the remit of an ISO/IEC 17025 quality system by a laboratory that has been accredited by UKAS, to ensure the consistency and accuracy of results.
