Founded in 1935, Hioki is one of Japan's top manufacturers of electronic measuring equipment and produced military measuring equipment for the U.S. Air Force in the 50s. In the field of electrical measuring instruments such as oscilloscopes and multimeters, Hiki has a good strength, and many of its products have a good reputation. For example, Hioki's oscilloscope current probes have always been the top in the industry, and in the category of handheld multimeters, Hioki is also the best in Japan. Although it is also aimed at the high-end market, there are slight differences between the Japanese and the previous top manufacturers. In addition to high-precision meters, it also has some portable multimeter products.
 
Card multimeters are the most portable multimeters and are usually less than 1 cm thick. The pen of this type of meter is directly attached to the body, unlike traditional multimeters that have a separate pen, so it is easier to take care of and suitable for carrying around when you go out. However, in order to achieve portability, the card multimeter also comes at a cost in terms of performance, especially the lack of current measurement function.
 
The 3244 and 3245 of the Japanese are very standard card multimeters, and the current price is 300~500 yuan. The two multimeters are three-and-a-half, with a number of 3999 and a length of only about 10 centimeters. Compared with the former, the 3245 has the function of solar charging, which can be said to be ingenious when used on the card multimeter. The two multimeters can measure basic voltage, resistance and on/off, although the accuracy is not high, but it is enough to do some basic measurements.
 
In terms of high-end products, Nioki has two multimeters, DT4282 and DT4281. To put it simply, these two multimeters are the top-of-the-line instruments positioned with the Fluke 287/289, also with a 60,000 count and 0.025% accuracy. In addition, both multimeters have an ABS automatic socket lock similar to Gossen. Although the durability and product construction are slightly inferior, compared with the Fluke 287/289, the two multimeters of the Japanese are slightly cheaper, with a price of 3200~3900 yuan. In addition to the well-established basic and additional functions, another feature of a top-of-the-line multimeter is its high frequency bandwidth. The AC frequency is within the bandwidth, so that the multimeter can measure the reading more accurately. Whether it is Fluke and Gossen's high-end products, or Hioki's DT4282 and DT4281, the maximum bandwidth is 1~100kHz, which is enough to cope with most measurement environments. However, users who purchase should note that these two high-end multimeters do not have a bar reading function.
 
If you need a bar reading to read voltage changes intuitively, the DT4250 series from Hioki is a good choice. There are a total of 5 instruments in this series, from DT4252~DT4256, and the product positioning and price are similar to Fluke's 115C/117C. 6000 readings with an accuracy of 0.3%, which is only slightly lower than the 0.5% of the Fluke 115C. However, it should be noted that there are many subdivisions of the multimeter of this series of Japanese companies, and the functions of most models are not as comprehensive as those of 115C or 117C, especially the 4254/4255 multimeters do not have current measurement functions. If you want to buy this series of products, it is recommended to buy a more comprehensive 4252 or 4256, the current price of DT4250 series is about 1000 yuan.
