Tachometer: We are the first domestic company to apply general-purpose single-chip microcomputers and use unique algorithms to localize tachometers. In 1998, the first tachometer launched. Later, we developed the tachometer with a new type of structural technology interchangeable between photoelectric and contact, and obtained the national utility model patent. Now a standard tachometer with a resolution of 0.01RPM has been developed, and the measurement accuracy has reached a new level. Since its launch, it has been selling well and has been well received. Hot Model: SM6234E SM6236E DT2236E

Digital Moisture Meter: It adopted the original analog electric technology to replace most of the LED segmented indicator type moisture meters on the market. Due to the originality of the circuit, no single-chip microcomputer, high precision, beautiful appearance and comfortable handle, MD812 is still the most cost-effective and most sold product in the past ten years. In the later stage, the non-destructive measurement of the inductive wood moisture meter MD918 was developed, which caused the export sales to increase year by year. The wall moisture meter MD 917 is widely used in home decoration and construction industries to help workers accurately grasp the moisture on the wall and the ground, and provide accurate and digital scientific basis for the subsequent processes.

Digital light meter: It uses military optical technology to prepare photosensitive probes instead of imported integrated sensors, which greatly reduces costs while ensuring measurement accuracy. It now developed to the second generation, with higher precision and better integration. In the past ten years, it has benefited users at home and abroad, and has maintained a higher ranking on Amazon for many year such as  model LX1330B   LX1010B.

Battery internal resistance tester: After the basic SM8124A came out, it was quickly recognized by the majority of users. In response to the rise of electric vehicles, mobile phones and other equipment, large-capacity battery applications have surged, and the micro-ohm (uΩ) SM8126A is introduced, which is more suitable for measuring large-capacity batteries. Compared with international famous brand products, the response speed is fast and the value is accurate. In today's era when batteries are commonly used, the demand for such meters is constantly increasing.

UV radiometer: It adopts self-developed filter and narrow-band precision measurement technology. In the past six years since its launch, sales at home and abroad have increased year by year. During the 2020 epidemic, UVC254 (UVC254 detects anti-virus and sterilization lamp) has made contributions to the fight against epidemics and epidemic prevention.

Screen brightness meter: More than ten years ago, a South Korean customer reported that South Korea produced all kinds of displays around the world and had a certain demand for screen brightness meters. So we developed SM208. After several improvements, it achieved outstanding sales in South Korea and Shenzhen.

Solar power meter: under the general trend of solar photovoltaic power generation, the company leaders keenly discovered a new project: solar power meter SM206-solar, and then developed SM206-PAR which specifically aims at "plant photosynthetically effective" light in modern agriculture. It will play an important role in agricultural production, scientific research, and horticultural flower planting.

Multimeter: The SM145E, which will be launched at the end of 2021, is a tool-level 4 1/2-digit digital multimeter, which applies innovative structural design and circuit design to increase the measurement speed (5 times/sec), reduce the shift frequency, and improve the measurement accuracy. The design facilitates the detection of SMD components and reduces procurement costs. It is an ideal tool for electronic engineers.
