The Hioki CM4373 AC / DC clamping amp is the most prominent in the line of high voltage test equipment up to 2000A. The machine has a pincer design and uses powerful sensing technology. In addition, the Hioki CM4373 has a wide measuring range that allows engineers and technicians to work quickly – accurately.
1. Diverse measurement of power parameters monitoring range to 2000A
The Hioki CM4373 features a wide range of precise and extremely safe power measurement functions for high voltage measurement requirements.
The Hioki clamp meter is the best measuring device incorporating Hioki’s professional features. Hioki CM4373 AC-DC clamp meter with True RMS technology reduces noise, measuring current up to 2000A. It has stronger clamps, and a wider operating temperature range of -25 ℃ to 65 ℃.
- AC / DC current measurement range up to 2000A.
- Measure AC / DC ~ True RMS ~ Accuracy: ± 1.3% rdg.
- Resistance measurement ~ accuracy: ± 0.7% rdg;
- Capacitance measurement: 1,000 μF to 1000 Μf.
- Frequency measurement: 9,999 Hz to 999.9 Hz.
- The Hioki CM4373 also has an indicator light and buzzer when testing continuity.
- Special support for measuring temperature (K): from -40.0 to 400.0 ˚C; Basic accuracy: ± 0.5% rdg.
It is used to measure high voltage system from outside, without affecting the operating system.
2. True-RMS measurement function and extremely precise peak value simultaneous measurement
Hioki CM4373 is capable of measuring true rms value True-RMS. This feature helps the user to operate effectively in power instability. True-RMS is a powerful solution that supports the highest accuracy user computing requirements. Ensure that the range of user-checked electrical values is the true r.m.s.value of the current operating current. Find out the cause more accurately and quickly. Hioki clamp amplifier CM4373 Also can measure at the same time the peak value of the current undergoing testing, effectively supporting the maintenance of power, saving time and maximizing user effort.
3. The clamp design supports the power sensor to greatly enhance the high voltage power measuring power
The Hioki CM4373 clamp meter has an improved measuring jaw. Increased strength many times compared to the old measuring jaw design before. When measuring high voltage circuits, the clamping jaws are significantly increased. The opening / closing cycle of a function is increased from 10,000 to 30,000 times. . Users are completely assured by the safety of the device and reliable results when performed.
4.Integrated automatic functions allow users to operate simply and easily in harsh real-world environments
The Hioki CM4373 is perfect for fulfilling all the power testing requirements. The machine is integrated with smart automatic functions: Auto hold, Auto hold MAX-MIN-AVG / Peak measurement, alarm and Led, … Auto hold function automatically saves after measurement results. This feature is extremely useful, when the experimental environment is difficult because of the narrow height, etc., which makes the user unable to read the results at that time. This makes it easy for users to compare – accurately calculate the causes of instability. In addition, there is support sounding alarms and red LED alerts when detecting dangerous situations. The Hioki CM4373 clamp meter supports quick measurement operations – more accurately and safely.
5. Meets IP54 standard for water and dust resistance; Allowable working temperature range from -25˚C to + 65˚C measurement results always ensure the highest accuracy.
Hioki CM4373 clamp meter meets IP54 standard “Dustproof_and_waterproof_performance” against dust and water ingress. This feature helps provide durability and minimizes measurement error. The IP50 measuring function maintains operational sensitivity, including exposure to sand or dust, and water droplets, and the Hioki CM4373’s ability to work in temperatures down to -25˚C or up to + 65˚C still works correctly.
