F490A (Force Indicator)

Quantity: In Stock

 

 

 

Product outline

F490A is a compact, lightweight handheld digital indicator for strain gauge type sensors that allows measurement of load, pressure and torque. The measurement data is recorded in CSV format in its internal memory, and the file can be referred to and copied through USB interface. F490A is equipped with fulfilling functions such as a variety of information displays, four types of hold functions including Peak and Valley, multi-calibration function that enables storing six channels of calibration values and allows them to be selected by a field sensor, and a HO / LO limit comparison function. The operation of AA alkaline batteries provides continuous use for approx. 30 hours*.

* Connectable to 350Ω series sensor while backlight is off.
