Ground Earth Resistance Tester Explosion Proof Type 0.01 to 1200Ω Alarm Function

Description

Clamp Earth Resistance Tester Explosion Proof Type 0.01 to 1200Ω Alarm Function
Instruction:
ETCR2000B+ Explosion Proof Type Clamp Earth Resistance Tester is our company's technology research and development team on technical quality of the pursuit of excellence, through continuous innovation to improve, upgrade with the old product. Its performance is mainly reflected in:
Breakthrough in self-test the boot a long time to waiting, start immediately into the test.
Breakthrough relay self-test mode, using the most advanced processing algorithms and digital integration technology.
Breakthrough the old product to heavy issues, more in line with characteristics of hand-held devices.
New design, panel operation with 6 buttons, better performance.
Increase sound and light alarm function, with "beep-beep-beep” alarm sound.
Increase the interference signal recognition indicator function, with "beep-beep-beep” indicator.
Measurement range: 0.01Ω-1200Ω
Stored data 99 Units. Lower power consumption, Maximum operating current less than 50mA.
ETCR2000B+ Explosion Proof Type Clamp Earth Resistance Tester is widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment. In the measurement of a grounding system with loop, does not require breaking down the grounding down lead, and no need the auxiliary electrode. It is safe, fast and simple in use. The tester can measure ground faults which cannot be measured by traditional methods. It can be used in applications where traditional methods cannot be measured, because theETCR2000B+ Explosion Proof Type Clamp Earth Resistance Tester measures the combined value of grounding body resistance and grounding lead resistance.
ETCR2000B + type clamp meter has passed the certification of explosion-proof and met GB3836-2000 explosive gas environment with electrical equipment. The explosion-proof marks is Exia
Ⅱ
BT3Ga. Explosion-proof qualified number:CE18.2380.It can be applied to the corresponding inflammable and explosive environment.
