SF6 Comprehensive Tester

New Products / New Technology

The SF6 comprehensive tester integrates SF6 humidity measurement, SF6 purity analysis, and SF6 decomposition product detection into a single device, consolidating functions that previously required three separate instruments into one.

SF6 density relay calibrator

The MD‑type SF6 density relay calibrator is a specialized instrument designed for the maintenance of SF6 switchgear in China's power system. It is the result of extensive research, incorporating cutting‑edge international technologies and design concepts to meet the unique requirements of SF6 switchgear servicing in the Chinese market. This device employs embedded microprocessor technology and integrates advanced international magnetic‑fluid sealing techniques to create a fully enclosed SF6 gas circulation system. Equipped with high‑precision pressure and temperature sensors, it enables convenient on‑site calibration of density relays. The calibrator can perform field verification of SF6 density relays with both contact‑type and current‑output configurations, and it can directly transmit measurement data…

SF6 Leak Alarm System

The UTADB8000 series SF6 gas leakage detection and alarm system is an intelligent, online monitoring solution designed and developed in accordance with the "SF6 Safety Regulations" to safeguard the health and safety of personnel working in switchgear rooms equipped with SF6‑filled equipment. It primarily measures the concentrations of SF6 and oxygen in the ambient air; when SF6 levels exceed permissible limits or oxygen levels fall below safe thresholds, it triggers real-time alarms and automatically activates ventilation fans. The system also offers a range of advanced features, including temperature and humidity monitoring, voice prompts for operational status, remote alarm transmission, and historical data retrieval. Its proprietary trace‑level SF6 detection technology enables quantitative measurement of SF6 concentrations, ensuring both personal safety and reliable equipment operation. Additionally, the imported high‑stability oxygen sensor provides an extra layer of dependable protection for on-site personnel.
