Description:
Meter Seal is security lock designed to lock metering equipment such as electricity, water, and gas meters. It features tamper-resistance, anti-counterfeiting, and self-locking functions, ensuring the accuracy of metering data and preventing unauthorized access or tampering. Widely used in the power, water, and gas industries, it serves as a critical physical measure to guarantee fair energy measurement and prevent electricity theft or water diversion. The seal body is typically made of PC polycarbonate or ABS engineering plastic, offering high transparency, weather resistance (-30°C to 65°C), and fireproof and corrosion-resistant properties.
The sealing wire is commonly 0.68mm in diameter, made of galvanized steel or stainless steel wire, with a tensile strength of ≥100N, ensuring it cannot be restored once damaged. Press-type seal: Easy to operate, suitable for single-meter enclosure, Twist-type seal: Forms a loop by threading metal or plastic wire through equipment seals, Usually, it can be laser-printed or hot stamped to add custom logos, serial numbers, QR codes, etc.
Reliable Tamper-Evident Security
The ST8507 meter security seal is designed to provide dependable protection for utility metering equipment. Once the sealing wire is inserted and locked into position, the seal forms a secure loop that cannot be opened without cutting or damaging the wire. Any attempt to remove or tamper with the seal will leave visible evidence, allowing inspectors and technicians to quickly identify unauthorized access. This tamper-evident function plays an important role in protecting the accuracy of meter readings and preventing unauthorized adjustments.
Durable ABS and PC Engineering Materials
The seal body is manufactured from a combination of ABS and PC engineering plastics, providing excellent durability and structural stability. These materials offer strong resistance to impact, weather exposure, and corrosion. The seal maintains reliable performance in temperatures ranging from approximately -30°C to 65°C, making it suitable for both indoor and outdoor installations. The robust material structure also ensures long service life in demanding utility environments.
High-Strength Sealing Wire
The ST8507 meter seal uses a high-quality sealing wire with a standard diameter of 0.68 mm. The wire is typically made from galvanized steel or stainless steel, offering strong resistance to pulling and cutting forces. With a tensile strength of at least 100N, the wire ensures the seal remains secure once installed. If the wire is cut or damaged, it cannot be restored to its original condition, ensuring clear evidence of tampering.
Simple and Efficient Locking Design
This meter seal is designed for quick and convenient installation in the field. The sealing wire is threaded through the meter locking holes and secured by the seal body, forming a tight loop around the equipment. The straightforward design allows technicians to apply the seal efficiently while maintaining consistent security standards across large-scale metering systems.
Clear Identification with Custom Printing
The ST8507 seal supports laser printing and hot stamping to add permanent identification information. Sequential numbers, letters, company logos, barcodes, and QR codes can be printed on the seal surface to support inspection records and equipment tracking. Clear marking improves traceability and helps prevent unauthorized replacement or duplication.
Multiple Color Options for Management
The meter seal is available in several standard colors including red, yellow, blue, green, and white. Custom colors can also be produced according to specific project or brand requirements. Color coding helps field teams quickly identify different service areas, inspection schedules, or management categories.
Flexible Wire Length and Practical Size
The standard sealing wire length is 25 cm, which suits most meter sealing applications. Customized wire lengths are also available to meet different installation requirements. The compact seal body size of 19.5 × 30.5 × 6.5 mm allows easy handling and installation while maintaining reliable security performance.
Suitable for Utility Infrastructure Applications
The ST8507 meter security seal is widely used for protecting water meters, electricity meters, gas meters, and other utility measurement devices. It helps prevent meter tampering, unauthorized access, and utility theft while ensuring fair and accurate measurement management across infrastructure systems.
