SDHT 2000 - Super Digital Hand Tester
SDHT 2000 - Super Digital Hand Tester
Pictured with 6" Platforms and Quick Change Load Cell

This is the heavy-duty version of our SDHT. Our most accurate manual tester, the SDHT 2000 has Quick Change load cells that allow you to measure grams to two decimal places, change the load cell and test up to 2,000 pounds. Its rugged two post design minimizes frame deflection and gives you the most versatility and productivity in a single tester.

The SDHT 2000 is made from a combination of billet aluminum and precision ground steel parts. The rack and pinion lever drive can be upgraded to our Micro Length Adjust assembly for fine length adjustments. The SDHT 2000 is also equipped with two positive stops to be used for repetitive testing and comes standard with a 0.437” Ø thru-hole for centering shafts for supporting buckling type compression springs. A stroke lock helps keep things in place while you take measurements or configure tooling. The tester has 5/8-18 tooling holes for convenient fitting.

  • Up to 72" range (18" standard)
  • Up to 36" stroke (13" standard)
  • Up to 8" Ø platform (2" standard)
  • Standard 0.0005" length resolution
  • 2 to 2,000 lb load capacities
  • SDHT software package

SDHT software includes these powerful features, making testing easy and productive:

  1. Limit Lights
    Part sorting and a statistical summary printout that includes a histogram and data run chart.
  2. Two-Point with Rate
    Test two points with spring rate calculation in one deflection of the spring.
  3. Calculated Free Length Measurement
    Calculate the free length of a compression spring.
  4. Initial Tension Measurement
    Calculate the initial tension of an extension spring.
