The current transformer tester is an important power equipment testing tool, used to measure the current, power and electric energy on the high-voltage or low-voltage line, and plays the role of insulation and isolation to ensure the safety of operators and instruments. Next, we will introduce to you the working principle, characteristics and how to detect the current transformer tester.

Anemometers, as the name suggests, are instruments for measuring air velocity. The anemometer has a wide range of applications and brings us a lot of convenience in measuring wind speed. So do you know how to use an anemometer? Now we will tell you how to use the anemometer, hoping to help you.

An anemometer is an instrument that measures air velocity. There are many types of it, and the most commonly used one in meteorological stations is the wind cup anemometer, which consists of three parabolic empty cups fixed on the bracket at 120° to each other to form the sensing part, and the concave surfaces of the empty cups are all in one direction. The entire sensing part is installed on a vertical rotating shaft, and under the action of wind force, the wind cup rotates around the rotating shaft at a speed proportional to the wind speed. Next, we will introduce you to the knowledge of anemometer.

An anemometer is an instrument that measures static and dynamic airflow, which can be used to measure wind speed, wind force and wind direction in the air. It uses a rotating blade and is measured in feet per second or meters per second (m/s). The accuracy of the anemometer is very high, and its readings can have very good accuracy in the range of 0.1 m/s. It can also measure wind speed under low temperature, low humidity and other environmental conditions, and can quickly and accurately measure the direction of airflow. So, how much do you know about the working principle of the anemometer? Next, this article will take you to understand the working principle and application knowledge of the anemometer.

Metal detectors are widely used in examinations, security checks, archaeology and prospecting, etc., bringing more convenience to people's lives. So how do metal detectors accomplish these tasks? Next, ATO will introduce the working principle, application and structure function of the metal detector to you.

Metal detectors may have various problems under long-term use, so we need to understand common problems and learn how to solve them. Next is the knowledge of metal detector troubleshooting, and I hope it will be helpful to those who need it.

The water leak detector is a device used to detect whether there are water leakage problems in water source equipment such as pipes, water tanks, and pools. Its working principle is to judge whether there is a water leakage problem by detecting the environmental changes around the water source equipment. Next, the ATO will introduce you to the working principle of the water leak detector.

Before using the pH electrode, it is very necessary to perform numerical calibration on it. The pH electrode calibration method refers to a method to make the measurement results of the pH electrode more accurate and reliable through a series of operations. Its main steps include cleaning the electrode, calibrating the electrode and judging whether the electrode needs to be replaced.

This carbon dioxide meter from SISCO combines CO2 detection and smoke alarm in one and can be used for air quality monitoring with a detection range from 400 to 5000 ppm. In addition, it can also provide real-time temperature and humidity data, allowing for full knowledge of your surroundings. Keep in mind when you purchase the unit you have to calibrate it first. And we’re here to help you with that. In this video, we’re gonna show you how to calibrate our CO2 meter.

We’re going to do a waterproof test on the SISCO metal detector and give you a brief idea of its practical application. But before we start testing, there’s some key info you should get noted.
