The Checkline ETX / ETPX datalogging tension meters are designed for accurate measurement of tension on fine wires, yarns and fibers in various applications. Rollers or Ceramic Pins are mounted at the end of long "fingers" permitting the user to measure tension with limited access space or when several lines are closely spaced such as on a warp sheet. Five (5) measuring ranges are available with a maximum capacity of 2000 grams or cN. The 1000 g and 2000 g capacity models have 7.4mm diameter V-Grooved Rollers mounted on shortened pins (fingers) instead of the standard length pins (fingers) and miniature 3.7 mm rollers.
New features include expanded memory for 60,000 data points in up to 999 batches, Hi-Speed Sampling of 200 Hz (1 kHz for Peak capture), Color, backlight TFT-display with 3 different displays modes: numeric, numeric with live bargraph, numeric with graph (time vs tension). The display auto rotates in 90° steps for optimal visibility regardless of the position of the tension meter.
