Tensionmeter Calibrations
To determine the Penn-Tech Cable Tensionmeter that will best serve your needs, start with a list of the cables you'll need to measure. We recommend that you do the research upfront: Be sure to choose the Tensionmeter that can handle the full range of cable diameters you may encounter. The TM-1000 is the most versatile Tensionmeter because it can be calibrated to measure cables ranging from 3/16" to 1 1/8" in diameter.

Standard Calibrations
Our "off the shelf" Tensionmeters are calibrated in 500-pound increments (ranging from 500 to 20,000 pounds) for galvanized extra high strength (EHS) cables listed in the table below. We stock TM-1000s with two calibration options: one calibrated to EHS only; the other calibrated to both the EHS and galvanized bridge strand (BS) diameters listed.

Model Cable 3/16" 1/4" 5/16" 3/8" 7/16" 1/2" 9/16" 5/8" 11/16" 3/4" 13/16" 7/8" 15/16" 1"

Custom Calibrations
You can have your Tensionmeter calibrated to any cable if the cable's diameter fits your Tensionmeter's diameter range. Note: One Tensionmeter can be calibrated for many different types and sizes of cable.

Model TM-600 TM-700 TM-800 TM-900 TM-1000
Diameter Capacity 5/16" to 5/8" 3/16" to 5/8" 3/16" to 3/4" 3/8" to 7/8" 3/16" to 1-1/8"

Contact us with a list of the cables you'll measure, specifying the construction and diameter of each. If your cable isn't among the hundreds we stock, we can calibrate a Tensionmeter to your 25-foot non-returnable sample. (See a list of the most popular types of cable we calibrate to.)

Custom Plotting
Tensionmeters are plotted in 500-pound increments ranging from 500 to 20,000 pounds. For an additional charge, we can calibrate your Tensionmeter in 100-pound or 250-pound increments.

IMPORTANT
Be sure to have your Tensionmeter calibrated for the specific construction, breaking strength, and diameter of the cable you're measuring. Bridge strand cable and EHS (as well as other types) are commonly used in the design of guyed tower structures, but their breaking strengths differ significantly.
