ETCR3000 Digital Earth Resistance Tester 0.01-2000Ohm Ground Resistivity Tester

Description

ETCR3000 Digital Earth Resistance Tester 0.01-2000Ohm Ground Resistivity Tester
ETCR3000 Digital Earth Resistance Tester
is elaborately designed and manufactured for the field measurement of grounding resistance, adopting digital and microprocessor technology ,  precision 3-wire or  simple 2-wire method to measuring grounding resistance, with unique line resistance verify function, anti-interference ability and environment adaptability, to ensure that long time measurement of high precision, high stability and reliability, which widely used in grounding resistance measurement of electric power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment etc.
ETCR3000 Digital Earth Resistance Tester
with unique line resistance verify function, which can measure the low value of ground resistance in the field more accurately and avoid the error caused by the change of the line resistance in long time usage; can avoid errors caused by the test wire incomplete insertion into instrument interface or bad contact; can avoid the error caused by changing or lengthening the test wire.
ETCR3000 Digital Earth Resistance Tester
is composed of main machine and test wire, etc. Host machine with large LCD display, white backlight, bar chart indication, clear at a glance.At the same time, it can store 400 sets of data, with maximum, minimum and average indication, historical data reading and accessing functions.
