Tensitron's Digital Strap Tension Meters measure tension(s) on metal, plastic, and other types of strapping and tie-downs.

The Model Tensitron STX-1 Digital Strap Tension Meters offers users utmost accuracy over a wide variety of materials.

The Model STX-1 series of Strap Tension Meters are designed to measure static tensions on metal, plastic, and other types of strapping and tie-downs. Indicate tensions in Lbs, daN or KG in these materials with tensions from 5 lbs to 2,000 lbs. The Model STX-1 series offers users utmost accuracy over a wide variety of materials.

  • Accurate
  • Dependable
  • Reliable


First select your material and its size. Next slide the center contact under the material and the two outer pins over the material and immediately get a tension reading on the digital display.


  • Large, easy to read backlit, color display with adjustable backlighting.
  • Display shows tension, name of material selected, minimum and maximum tension values, dynamic color bar graph indicating changing tensions and battery charge level
  • Select tension values to display in Lbs., daN or KG
  • Up to 10 additional custom calibrations may be programmed into the instrument
  • Extremely accurate custom calibration procedure employing up to a 10-point multilinearization procedure.
  • All calibrations are password protected
  • Adjustable LCD refresh rates allowing for stable, digital readouts
  • Automatic shutoff after several minutes of non-use
  • Instruments may be operated continuously while connected to power supply
  • Data Logging Feature. Record tension values to the instrument’s memory.
  • Data Statistics: Monitor your process by viewing count, average and standard deviation values of your logged data.
  • Data Averaging: Use this feature to adjust the stability of your displayed, tension readings. This feature allows the user to select the duration the instrument takes tension readings over and posting that average to the display. Options are: 1, 2, 5 and 10 seconds. This is a rolling average, meaning that only the readings taken in the last 1, 2, 5 or 10 seconds (your choice) will be averaged and displayed.
  • Set-Point feature allowing user to define high and low point specifications which are then shown on the main display as an active, color changing bar graph.
  • Rechargeable NiMH batteries with power supply provided. Approximately 12 hours of continuous use depending upon backlighting intensity.
  • Power supply operates with input voltages from 100 – 240V and includes several, interchangeable adapters allowing use with European, Australian, US, English and other plug configurations.
  • Optional features including: Analog Output and Serial Output
  • All models typically available from stock
  • Numerous application specific models available
  • Durable, lightweight carrying case with protective foam inserts
  • All instruments factory-calibrated and ready for use. Calibration certificate included and all calibration values traceable to National Standards


  • battery charge level
  • Selectable Tension in Lbs., KG or DecaNewtons
  • Select Strapping and Size. Instrument automatically adjusts calibration
  • Active, color changing Bar Graph
  • Minimum and Maximum tension values

STX-1 series instruments are calibrated specifically to your strapping type(s) and size(s) to insure the greatest accuracy possible. When ordering specify: Material, width and thickness of the Strap.

Available options for all Instruments


Analog Output Option
0-5 VDC of 4-20mA with software definable ending sequences. Provided with 10’ cable and data outputted at 40 Hz


RS-232 Serial Output Option
Provided with 10’ cable to interface with your receiving device. Select data sampling rate from 1, 2 or 5 Hz.

Serial Data Collection

Instruments outfitted with the optional RS-232 feature (designated with an " -E" in the part number) support serial data. The Serial Data option includes a RS232 cable assembled with a male, DB9 connector (allows serial communication using a 9-pin connector) along with a USB to DB9 adapter.

Your receiving device will require a "software wedge" in order to upload data from the instrument and there are many of these programs to choose from.

(If you require a "software wedge" program there is "freeware" software available as long as it is not used in countries with encryption restrictions [US, Europe and Canada are fine] and usually this "freeware" does not need to be installed to operate.)


  • Approximate weight: 2.3 Lbs depending upon configuration
  • CE certification complying with heavy, industrial immunity standards
  • FCC certification
