Sanwa is another well-known instrument manufacturer in Japan, at the beginning of its establishment in 1941, Sanwa was mainly engaged in the production of circuit instruments for equipment maintenance, and its products are currently sold in more than 70 countries around the world. The multimeter is the core product of Sanhe, but unlike many manufacturers, Sanhe is more accomplished in the analog multimeter.
Sanhe is currently one of the strongest pointer multimeter manufacturers, the analog meter, also known as the analog meter, which relies on the deflection of the pointer on the dial to read the reading. This kind of multimeter has a lot of defects, one is that the input impedance of the pointer meter is not high, so it will interfere with the circuit when measuring the circuit, and it is far less accurate than the digital meter, and the reading of the dial by eye will also produce errors, so the popularity of the pointer meter is not high now. However, when it comes to measuring variable circuits, the readings of the analogue meter are very intuitive, and the "bar reading" function of many high-end multimeters mimics this feature. In addition to Sanhe, Simpson in the United States and Shanghai Sibiao in China are all strong analog multimeter brands.
With experience in analogue meters, Sanwa also performs very well on digital multimeters. Different from Hioki, Sanhe is positioned between foreign high-end brands and domestic cost-effective brands, providing a transitional space for two products with different styles.
In terms of high-end multimeters, Sanhe PC7000 and PC720M products are good. The PC7000 has a 50,000 count and 0.03% accuracy, and includes almost all the mainstream functions of the multimeter, as well as peak, low-pass filter, PC connection and other functions. In terms of parameters alone, Sanhe and these two multimeters are also slightly weaker than the Japanese DT4282. The disadvantage of the PC7000 is that it lacks a 50mV step and has no data storage function. The PC720M, on the other hand, only has four digits for 9999 counts. But on the other hand, the price of these two multimeters is around 3000 yuan, which is more cost-effective.
In addition to the high-precision multimeter, the Sanwa CD772 with 0.5% accuracy, true RMS, and automatic range is also a good product. In addition, Japanese manufacturers are quite accomplished in portable instruments, and the Sanwa PM series is a very good card multimeter. The PM300 in the series has more comprehensive functions, it is a true effective value, and the maximum value of data can be recorded, and the price is about 600 yuan. However, when buying this type of product, it should be noted that card multimeters generally do not have a current level.
