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The mechanical Strap Tension Meters have been replaced by the far more accurate much more rugged STX-Series of digital strap tension meters however Tensitron will still repair these old analog dial meters.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 instrument’s 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 instrument’s 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 l000 lb (or 500 kg) with specific calibrations to the materials used.
