The LK100 and LK800 leak calibrators are the optimal accessories for checking and adjusting the JW Froehlich Series 100–500 leak test panels. Convenient to use, battery operated and rechargeable via a USB interface, the measuring devices are flexible and therefore well suited for use in a workshop. A variable, adjustable leak rate range makes certain that no matter the testing and adjustment tasks, the leak calibrator is fit for use and no additional devices are necessary.
