How to Select Suitable Instruments and Meters

How to Select Suitable Instruments and Meters

In modern construction, there are high-level technical requirements for the monitoring functions of instruments, making the instrument industry a leading sector that promotes technological progress, technical transformation, and improved labor productivity and economic efficiency across national economic sectors‌. The equipment level of instruments significantly reflects a country's productive forces and modernization in science and technology. With advancements in computer technology, testing equipment is increasingly shifting toward intelligence—smart instruments, which have become a key development direction‌.

Key Considerations for Selection

Accuracy Class‌

Follow national standards (e.g., ‌GB/T 13283-2008‌) to determine accuracy classes (e.g., 0.1, 0.2, 0.5, 1.0, 1.5, 2.5, 4.0), where lower numbers indicate higher precision‌.

Example: Class 0.5 (±0.5% FS) suits industrial process control, while Class 1.0 (±1.0% FS) is for general applications‌.

Application Scenarios‌

High-precision‌ (0.1–0.2): Laboratories, aerospace‌.

Industrial-grade‌ (0.5–1.5): Chemical plants, water treatment‌.

Basic monitoring‌ (2.5–4.0): Agriculture, simple tank measurements‌.

Intelligent Features‌

Smart instruments integrate automation and AI, enhancing efficiency and data analysis‌.

Supplier Evaluation‌

Verify supplier qualifications, maintenance support, and compliance with ‌GB/Z 27427-2022‌ for lab equipment‌.

Practical Steps

Define Requirements‌

Specify parameters (e.g., range, accuracy, environment).

Compare Standards‌

Match instrument classes to operational needs‌.

Assess Compatibility‌

Ensure interfaces and software align with existing systems‌.

Future Trends

The field of measurement and control technology, merging automation, instrumentation, and AI, promises robust career opportunities‌.

Note: For detailed technical specifications, consult ‌GB/T 13283-2008‌ or industry guidelines‌.
