Since 1976, it has been IET Lab's mission to manufacture very high-quality instruments at competitive prices while providing a level of hospitality not often found in the industry. By combining the many hundreds of man-years of engineering experience of GenRad, esi and IET, we have become the world's preeminent manufacturer of impedance instruments, offering from the most cost-effective to the most stable electrical standards. IET Labs is small enough to offer the individual exceptional service each of our customers deserves, while large enough to offer the world's most complete impedance solutions with over 1300 different products.
