ETPB-ETPX Data Logging Limited Access Digital Tension Meter

Made in Germany3 Ranges
0.5 - 100, 1 - 200, 1 - 500 (g or cN)


Three long, closely-spaced slender shafts with precision guide rollers or pins at their ends combine with the latest in microprocessor technology to make this instrument top choice for all limited-access, tension measuring applications.

Store up to 4000 displayed tension values in memory and statistics (Last, AVG, MIN, MAX, MIN-PEAK, MAX-PEAK), which can be transmitted using the serial output port.

ETMX models feature miniature, high speed rollers for filament speeds up to 2000 m/min. ETMPX models features non-rotating, ceramic pins for speeds to 6000 m/min.

Reversible display for right or left-hand operation

  • User Selectable Units Grams or Centinewtons
  • New filament guide for easy acquisition of material
  • Adjustable damping for easier readings when tension fluctuates
  • Backlit LCD Display
  • 0-2 VDC analog output for connection to a chart recorder or datalogger
  • USB output for batch download or real-time data transfer to TensionInspect Software
  • TensionInspect Software plus USB cable provided FREE
