PRODUCT INTRODUCTIO
| MEWOI7450 clamp multimeter is a new generation of practical electrician measuring instrument with excellent performance carefully developed by our company. The instrument adopts a high-performance new MCU processor, and the instrument has a very high cost performance. It has the characteristics of high reliability, high security, automatic range, and handheld clamp meter. With super large screen digital, full range overload protection, data retention, undervoltage prompt, automatic shutdown function, true effective value measurement can accurately measure frequency conversion voltage, non-sine wave voltage, and surge current can measure the effective value of surge current with a period of 80mS , and equipped with a temperature measurement function that can accurately measure -50~1000°C, this instrument is very suitable for variable frequency power supplies, air conditioners, refrigerators and other refrigeration equipment, motor performance testing, etc. The DC current function of DC40A, 400A, 1000A range is widely applicable Electroplating, DC welding machine, automobile inspection and various DC current measurement occasions above 500mA. This meter can be used as an ideal tool for detection, maintenance and repair of various colleges and universities, smelting, communication, manufacturing, petroleum, national defense, electric power, electronics and electric power equipment. It provides a safe, accurate and convenient new power meter for electricity inspectors, and is an essential tool for electrician safety inspection. |
