Digital tachometer RPM

for boatsblack6 V

Digital tachometer for measuring angular and linear velocity. The optical model is suitable for applications where the instrument cannot have physical contact with the moving object or must avoid any braking effect; the contact model uses rubber and roller tips for contact with the moving part. Its compact size, shock resistant case and easy operation makes this tachometer ideal for all industrial and marine environments. • Optical or contact monitoring of rpm • Complete set of accessories and carrying case • Can be combined with external probes (models 8406 and 8455) • Totalisation function • Display-hold of last measured value • Reading points: 19999 or 99999 • Display: 4 digit or 5 digit, 7,6 mm red Led • Stability: ±0,015% /°C max • Optical working distance ranges: 10…300 mm • Power supply: 4 x 1,5V AA batteries supplied • Autonomy: ~ 20 hours • Low battery warning • Optical dimensions: 65 (A) x 180 mm (B), black ABS • Contact dimensions: 65 (A) x 215 mm (
