The SPR-962 Infrared Belt Tension Tester is a compact, laser-based tool designed for quick and accurate measurement of belt tension in motors and machinery. Utilizing advanced laser sensing technology, it calculates tension by detecting the belt's natural vibration frequency, eliminating the need for mechanical contact. Ideal for maintenance and industrial applications, it offers metric and imperial unit options and is suited for narrow spaces.
- Laser Sensor Technology: Non-contact measurement for precision and convenience.
- Split Sensor Design: Compact (66mm depth) for use in confined spaces.
- Multi-Unit Display: Supports metric (m, kg/m, N) and imperial (inch, lbs/ft, lbf) units.
- Automatic Calculation: Computes tension using belt mass, free length, and vibration frequency.
- User-Friendly Interface: LCD display with intuitive keypad controls.
- Portable & Durable: Lightweight (180g) with a rugged carrying case.
- Auto Power-Off: Energy-saving feature after 3 minutes of inactivity.
