STRAP TENSION METER - Model STM-Series
For Metal & Plastic Strapping - Direct Reading Dials in lb or kg
The mechanical Strap Tension Meters have been replaced by the far more accurate, much more rugged STX-Series of digital strap tension meters, however Tensitron will still repair these old analog dial meters.
Each instrumentís model number denotes its maximum tension limit, for example a model STM-200 measures tension up to a maximum of 200 lb, and a model STM-150kg measures as high as 150 kg. The meters work best when indicating mid-range values, not the extreme high or low values, therefore we suggest you only use the meters on materials where your expected tension readings are one-half the instrumentís maximum range.
The mechanical meters can only be calibrated to one type of strapping. Typical strapping material requires a measuring tension well below 200 lb. The most commonly used instrument model, the STM-200, measures tension up to 200 lb and is calibrated to 3/8" x .020" (approx. 9 mm x .5 mm) plastic strapping. Other strapping materials may require tension readings up to l,000 lb (or 500 kg) with specific calibrations to the materials used.
