On September 16, 2025, Tektronix officially announced the 7 Series DPO Oscilloscope, opening a new generation of ultra-high performance oscilloscopes. This is a series of oscilloscopes designed to provide the lowest noise, highest ENOB, and support bandwidth up to 25 GHz right from the launch.

In the technical world, especially those who work in mechanics, construction or material research, the concept of strain gauge is probably not unfamiliar. One of the devices that plays an extremely important role in measuring, analyzing and controlling the quality of construction and products. Many people who are new to it often think it is complicated at first, but in fact, if you understand the principles and how to use it, the strain gauge is quite friendly and easy to apply in many situations.

Many people who are new to aquascaping often wonder about the TDS index in the tank, not knowing what level to keep it at and what to do when it is too high or too low. After a long time of being involved in this hobby, I have gained some experience and want to share it for your reference.

Moisture balances (also known as moisture analyzers) are increasingly trusted by many units in the food, pharmaceutical and laboratory sectors. Compared to traditional oven drying, this type of balance is integrated with more intelligent features, both shortening the time and increasing accuracy. If you are wondering whether to choose a moisture balance or continue to use an oven, the following sharing will help you make a more reasonable and effective decision.

In a cup of coffee, more than 98% is water. It sounds simple, but this water determines a lot of the flavor. The remaining less than 2% is the coffee dissolved in. Therefore, water quality plays an extremely important role. Factors such as total dissolved solids (TDS), hardness or pH index all directly affect whether the brewed coffee is delicious and rich or not.

Coffee that is stored incorrectly can easily get moldy, lose its flavor, and even spoil the whole batch. One of the main reasons lies in the way you store it. It sounds easy, but it will be a decision that affects the quality of the beans to some extent. So the question is: what is the humidity of the coffee to keep the flavor delicious and safe for a long time? This article I will share more specifically for your reference.

Are you sure you really understand all the buttons and symbols on the clamp meter you use every day? Just bought one and don't know where to start?

In electronics, every system is shaped by frequency. A microprocessor can only sustain its ability to perform billions of calculations per second if its clock is operating at the right speed. Cellular base stations can only maintain stable communications if the carrier frequency does not drift even a fraction. With radar, the ability to detect and locate a target depends entirely on the accurate analysis of each echo. In every scenario, frequency is the “red thread” that holds the entire operation together.

Manganese is a metal that is widely used in many areas of life and production. However, not everyone fully understands its role. In this article, I will join everyone to learn more clearly and practically about Manganese. We will start from the atomic structure, delve into the importance of Manganese in the metallurgy and steel production industry. In addition, Manganese also appears in agriculture with direct impacts on crops. Finally, there are safety warnings that anyone working or exposed to Manganese should pay attention to.

In recent years, a brand from Korea has emerged in the Vietnamese market, which is SH Scientific. Many customers ask EMIN, is this a good choice or not? Is the advertisement true to reality? With my experience, today I will "dissect" this furnace with you, from its outstanding advantages to the problems we often encounter.
