Home > Products > Meter Seal
Meter seals are tamper-evident security devices specifically designed to protect electricity, water, and gas meters, as well as related utility equipment. More than just a locking device, they function as a forensic security tool by providing clear and visible evidence of unauthorized access or interference. These seals are widely used by utility companies, inspection authorities, and maintenance teams to ensure operational integrity and prevent tampering.
Manufactured from high-quality materials such as polycarbonate, ABS resin, stainless steel, and galvanized steel, meter seals feature a compact yet highly durable structure. These materials offer strong resistance to environmental factors such as temperature changes, moisture, and mechanical impact. Each seal is equipped with unique identification features including sequential serial numbers, barcodes, or QR codes, allowing for accurate traceability and authentication. Designed for one-time use, the seal will be permanently damaged once removed, ensuring it cannot be reused.

Widely used across multiple industries, these security seals are specifically designed for applications requiring strong anti-tampering protection and integrity assurance throughout operation and handling processes.
1. Utility & Energy Metering
Applied to electricity meters (smart and mechanical), water meters, gas meters, and heat meters to prevent tampering, bypassing, and data manipulation, ensuring accurate billing, protecting utility revenues, and maintaining fair and reliable measurement systems.
2. Power & Water Supply Facilities
Used for sealing distribution boxes, transformer cabinets, valves, fire hydrants, and pipeline systems to prevent unauthorized access or operation, ensuring the safe, stable, and continuous functioning of public infrastructure facilities.
3. Industrial & Commercial Equipment
Widely used in fuel tanks, petrol pumps, chemical containers, weighing systems, and storage units to prevent theft, contamination, and unauthorized opening, ensuring product safety and measurement integrity.
4. Logistics, Transportation & Supervision
Applied in containers, transport vehicles, inspection devices, and regulatory equipment across logistics, customs, banking, and security sectors to prevent tampering during transit and ensure full traceability and control.
1. Excellent Tamper-Evident Performance
Any unauthorized disassembly or removal will leave obvious and irreversible traces such as breakage, deformation or surface damage, which can be easily identified on site without professional equipment, effectively preventing man‑made tampering.
2. High Durability & Weather Resistance
Made of high-strength materials such as PC+ABS, meter seals feature good impact resistance, UV resistance, high and low temperature resistance and corrosion resistance, suitable for long-term use in both indoor and harsh outdoor environments.
3. Easy & Fast Installation
Most models support tool‑free or simple tool operation, enabling quick locking and sealing, which greatly improves construction and inspection efficiency.
4. Cost‑Effective & Highly Reliable
With low comprehensive use cost and stable protective performance, they provide long‑term effective security control with high cost performance.
5. Strong Customization
Support customization of colors, logos, serial numbers, codes and other markings to meet the differentiated management requirements of different industries and users.
6. Compliance & Traceability
Help enterprises and institutions meet industry specifications and regulatory requirements, improve management standardization, and facilitate responsibility tracing in case of abnormal opening or tampering.
7. Eco-Friendly: Recyclable and biodegradable materials.
