  • Data can be downloaded to EZ Data software for complete data management
  • 5.7 inch touch screen display
  • Universal input voltage from 85-265 VAC(50/60Hz)

Data Acquisition System

  • The ChemInstruments electronic data acquisition system is a state-of-the-art microprocessor controlled force measurement package that combines accuracy with ease of use. This system simultaneously controls test motion, reads the force of a test from a load cell, digitally displays it and also stores that data in its memory.
  • Samples at 2000Hz, 2 samples are collected, averaged and stored as a data point. A test will generate a data point every 1ms
  • Displays a graph of all measured force values upon completion of a test
  • Displays the high and low measured force results immediately upon completion of a test
  • Export data by USB connection to a local PC with our EZ Data software
  • Displays test values in grams, kilograms, ounces, pounds or Newtons


  • EZ Data Compatible Remote setup, operational control and enhanced data collection are all possible when coupled with our EZ Data management software. This application requires an external PC. (See more information about the EZ-Data product)

Some of the more popular test methods that this device is capable of performing:

  • ASTM: D 2979

The Polyken™ Probe Tack from ChemInstruments makes it easy to measure the tack of pressure sensitive adhesives. A precision ground 5.0 mm diameter flat probe contacts the adhesive, reverses direction and pulls away from the adhesive. The maximum force required to break the adhesive bond is recorded and displayed. The Polyken™ Probe Tack adhesive testing machine meets the standards set forth in ASTM D2979. Machine speed is 24 ipm (61 cm/m), probe diameter is 5 mm and it has an annular ring which applies the standard pressure of 9.79 +/-0.10 kPa. An automatic test cycle produces a 1 second dwell time from the beginning of contact to the end of contact.
