DI-4B-25 Digital Torque Tester for Air Tools & Impact Wrenches

Air Tool & Impact Wrench Digital Torque Tester

Standard Features

  • Heavy duty metal construction
  • Easy to read LED panel displays torque value in lbf-in, kgf-cm and N-cm (selectable), number of blows for selected period (0.1 – 9.9 sec)
  • Peak, Real Time and Peak Down measuring mode (selectable)
  • Accuracy: ±0.5% F.S. ±1 LSD (32° to 100°F)
  • Both clockwise and counterclockwise operation
  • USB Virtual COM port (peak data only)
  • Runs on internal NiMH batteries (8 hour use)
  • Soft joint, hard joint and AC adapter/charger included

The DI-4B-25 Digital Torque Tester is perfectly suited for on-the-spot calibration of air tools and impact drivers up to 220 lbf-in. In production facilities it is crucial to check the consistency of air guns and impact wrenches.  This torque tester gives a digital readout of peak value in either clockwise or counterclockwise directions and also indicates the number of blows for a selected time period (adjustable). The DI-4b-25 torque tester features 3 measurement modes: Peak Down, Peak, or Real Time measurement modes and selectable units lbf-in, kgf-cm, N-cm. Calibrate your own air tools and impact drivers and save down time.

SPC Capability

This digital torque tester has an accuracy of ±0.5%, ±1 LSD, Peak, Real Time and Peak Down modes. The DI-4B-25 is compatible with Imada’s SW-1SV-USB Torque Data Acquisition Spreadsheet. Peak data can be downloaded through the USB virtual COM port to be analyzed further in Excel.

What’s Included

The DI-4B-25 torque tester is sold as a kit. All kits include the torque tester, hard and soft joints, AC adapter/charger and carrying case. The unit runs on internal rechargeable batteries (8 hours continuous use). All new testers include a 3-point calibration certificate traceable to NIST. ISO-17025 certificates are available at an additional charge.
