High-accuracy AC/DC clamp meter with multimeter functions for comprehensive diagnostics.
Advanced clamp meter with data logging, Bluetooth, and power quality analysis.
Precision digital instrument for accurate grounding resistance measurement.
Remote phase verification for high-voltage systems with wireless transmission.
All-in-one solution for insulation resistance, polarization index, and dielectric discharge testing.
All ETCR instruments comply with IEC 61010 safety standards, ensuring operator protection during high-voltage and high-current measurements.
Incorporating digital signal processing, wireless communication, and smart algorithms for accurate and reliable results in noisy environments.
Rugged construction, IP-rated enclosures, and long battery life ensure performance in harsh field conditions.
Clamp-type testers measure grounding resistance without disconnecting the system using a current clamp, ideal for live systems. Digital testers use the 3-pole or 4-pole method with auxiliary electrodes for higher accuracy but require system disconnection.
Yes, many ETCR high-voltage insulation resistance testers include automatic PI, DAR (Dielectric Absorption Ratio), and DD (Dielectric Discharge) calculation functions for comprehensive insulation assessment.
Yes, advanced models like the EM6530 and EM6670D support internal data logging with options to export via USB or Bluetooth to PC or mobile devices.
All ETCR electrical testers are designed and manufactured in compliance with IEC 61010 safety standards for electrical measurement equipment, ensuring CAT III/CAT IV ratings where applicable.
