ETMX - ETMPX数据记录张力计

ETMX - ETMPX Data Logging Limited Access Digital Tension Meter

3 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.
