Earth resistance tester EM-4055 has a built-in memory to store measurements and a built-in printer (optional). The earth resistance tester is a portable, strong and lightweight equipment, suitable to be used out in the field and under severe weather conditions. The tester is powered by a rechargeable battery with a 110V or 220V charger and it is supplied with all the necessary accessories for measurements (test spikes, leads, etc) within an auxiliary case that makes it simple to carry. The USB interface allows to communicate measured values between earth resistance tester and computer or data logger for their later analysis.
