BTM-400PLUS Belt Tension Meter, Handheld Digital Belt Tension Gauge, 10-800 Hz for Flat, V & Ribbed Belts, Kit with Sensors, Battery & Hard Case, 1 Kit

When precision and speed matter, the Checkline BTM-400PLUS gives you both in a handheld instrument built for field and shop use. This meter measures static tension of flat, V, and ribbed drive belts by tapping the belt and reading its natural vibration frequency—then converting that into tension units (Newtons or pounds-force). With a measuring range from 10 to 800 Hz, it handles a wide spectrum of belt types and drive systems. Its jewel-bright LCD display shows either frequency or tension in your chosen unit, and the optical sensor is built to ignore ambient noise and magnetic interference—so you get accurate results even in busy or industrial environments. Whether you’re servicing automotive accessory belts, inspecting machine-room drive systems, or checking equipment in manufacturing, this tool saves you the trouble of bulky setups or guesswork. The compact form lets you carry it into tight spaces and field sites where every minute and every reading counts. By using the correct tension, you extend belt life, reduce downtime, and protect your equipment investment. Compact, professional, and built for repeatable tension checks—that’s the BTM-400PLUS in action. The ergonomically designed unit comes in a rugged foam-fitted hard case. Your complete kit includes: 2 x Sensors (plug-in for quick use, cable-connected for tight spaces) 1x Nine-volt battery 1 x User manual
