ETM2
Limited Access Digital Tension Meter |
3 Ranges
0.5 - 100 g, 1.0 - 200 g, 1.0 - 500 g
2 Models
ETM2 (Basic unit)
ETM2X (with memory and outputs)
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.
Choice of miniature, high speed rollers for filament speeds up to 2000 m/min or non-rotating, ceramic pins for speeds to 6000 m/min. Uses part number ETMP2 or ETMP2X to designate model with ceramic pins. |
 User Selectable Units Grams or Centinewtons | | New filament guide for easy acquisition of material | | Reversible display for right or left-hand operation |
| | Choice of miniature, high speed rollers for filament speeds up to 2000 m/min or non-rotating, ceramic pins for speeds to 6000 m/min.
| | Adjustable damping for easier readings when tension fluctuates |
|
| • Storage of MIN, MAX and PEAK tension values which can be recalled or downloaded to a PC
• Output voltages for a recorder, parallel printer or remote display |
