Klaric Measurement Solutions

last updated：Jun 26, 2025

A measurement solution for more efficient and rational measurement of voltage, current, and temperature of electric components in vehicles (EV, HEV, PHEV).

We comprehensively solve the challenges of measuring voltage, current, and temperature in vehicle electrical components. With more efficient and rational measurement functions, we achieve safe and accurate in-vehicle measurements. We minimize the hassle and failures associated with in-vehicle measurements, contributing to the efficiency of testing. ■ We rationally detect electrical signals using voltage and current probes specifically designed for in-vehicle measurements with insulation treatment. ● This prevents leakage and short-circuit accidents, allowing for safe measurements. ● Efficiently detects electrical signals. ● Particularly in current measurement, the built-in shunt resistor in the probe dramatically reduces the preparation work for testing. ■ The probe auto-recognition function reduces setup errors during testing. ■ The auto-range switching function measures the standby current and operating current of electrical components with optimal resolution. ■ The dynamic sampling rate function dramatically reduces the amount of data during standby of electrical components while accurately capturing transient changes during operation. ■ By outputting measurement values via CAN signals or Ethernet, we synchronize data collection with signals from other devices.
