CácUHV-620 SF6 Gas Dew Point Tester Dew Point Analyzer Moisture Water Content Tester launched by ultra-high voltage is redefining the industry standard for gas insulation monitoring. This cutting-edge device, known as the power system, has unparalleled accuracy in detecting moisture and gas purity, ensuring the reliability of critical power infrastructure.

Key Features & Innovations

1、Ultra-Precise Diagnostics

Measures dew point temperatures as low as -80°C with ±0.5°C accuracy, identifying even trace moisture that could compromise insulation.

Quantifies H₂O content in ppmv or mg/m³ and verifies SF6 gas purity (0-100%) in one integrated test.

2、Intelligent Automation

Self-calibrating sensors and built-in gas pumps enable rapid, hands-free operation—results in just 3-5 minutes.

Real-time color touchscreen display with trend graphs and customizable alarms for out-of-spec conditions.

3、Field-Ready & Eco-Conscious

Portable, battery-powered design (8+ hours runtime) for substation or remote site testing.

Complies with IEC 60480 and DL/T 506 standards, supporting global efforts to reduce SF6 emissions (a potent greenhouse gas).

Why It Matters

Moisture contamination in SF6-insulated equipment (e.g., GIS, circuit breakers) can lead to arc flashes, equipment failure, or costly outages. The UHV-620’s dual-function testing (dew point + purity) allows utilities to:

1、Prevent failures by detecting leaks or degraded gas early.

2、Extend equipment lifespan through proactive maintenance.

3、Meet strict regulatory requirements with auditable test reports.
