Product Description:
space
The 2830 Series have a functional cover/dial design with sharp, bold, high-visibility numerals and legend. The pointer and scale are on the same plane eliminating parallax. They provide virtually friction-free operation, greater sensitivity, repeatability without tapping. They are shock and vibration resistant. Strong steel cases give a classic industrial look that maintains accuracy and prolongs life. Both transducers and signal-conditioning circuitry are integral. space
