In the field of instrument calibration and testing, there are clearly defined categories, contents, and characteristics. However, for those unfamiliar with the metrology industry, these concepts may seem unclear. This article will provide a detailed introduction to the core concepts of instrument calibration and testing, including its content, classification, and features. Content of Instrument Calibration

Introduction In hazardous environments where explosive gases, vapors, or dust are present, electrical installations must adhere to strict safety standards to prevent ignition sources. One of the key considerations in such installations is whether to use flexible conduits. While they are not always mandatory, flexible conduits are often required in specific situations to ensure safety

Introduction In modern industrial automation, Configuration and Human-Machine Interface (HMI) are two fundamental concepts that play a critical role in intelligent control systems. While these concepts might seem straightforward, their functionalities are profound and indispensable. This article provides an in-depth exploration of these concepts, discussing their definitions, functions, key technical features, and widespread applications in

Thermoresistors are critical components in chemical instrumentation for accurate temperature measurement. Proper inspection of these devices is essential to ensure they function correctly and provide reliable data. Below are the detailed steps for inspecting thermoresistors: 1. Visual Inspection Protective Sheath Check: Examine the thermoresistor’s protective sheath for any visible damage, such as cracks, deformation, or

pH instrument calibration is an essential procedure for ensuring accurate pH measurements. There are two primary methods for calibrating pH instruments: the colorimetric method (using pH paper or colorimetric vials) and the electrode method. While colorimetric methods do not require calibration, the electrode method must be calibrated because it involves comparing the unknown solution’s pH

Introduction Level measurement is a critical aspect of industrial automation, especially in complex environments. Selecting the right level measurement technology is crucial to ensure accurate and reliable readings. Radar level sensors and ultrasonic level sensors are two commonly used non-contact technologies for level measurement, each relying on different principles—microwaves and sound waves, respectively. Although both
