For accurate calibrations, Penn-Tech Tension Meters should be serviced by Penn-Tech or a Penn-Tech-authorized calibration lab.
Tension Meter Calibrations
To determine the Penn-Tech Cable Tension Meter 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 Tension Meter that can handle the full range of cable diameters you may encounter. The TM-1000 is the most versatile Tension Meter because it can be calibrated to measure cables ranging from 3/16" to 1 1/8" in diameter.
NEW
Each Tension Meter COMES COMPLETE with the accessory saddles listed, TPT Contractor©, calibration charts, calibration verification tool, PTI cable gauge and a hard-plastic carry case with die cut ethafoam protection to house the Tension Meter.
Standard Calibrations
Our "off the shelf" Tension Meters are calibrated in 100-pound increments (ranging from 100 to 35,000 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.
Custom Calibrations
You can have your Tension Meter calibrated to any cable if the cable's diameter fits your Tension Meter's diameter range. Note: One Tension Meter can be calibrated for many different types and sizes of cable.
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 Tension Meter to your 25-foot non-returnable sample. (See a list of the most popular types of cable we calibrate to.)
Custom Plotting
Tension Meters are plotted in 100-pound increments ranging from 100 to 35,000 pounds.
IMPORTANT
Be sure to have your Tension Meter 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.
