VT-DGA600 6-Gas Online DGA Monitor
VT-DGA600 6-gas online DGA monitor — comprehensive fault gas detection with PAS technology, IP65 rated.
VT-DGA600 6-Gas Online DGA Monitor
Comprehensive 6-gas monitoring with PAS technology for reliable early fault detection.
Overview
The VT-DGA600 delivers comprehensive 6-gas DGA monitoring in a compact, IP65-rated enclosure. Measuring all key fault gases (H2, CO, CH4, C2H2, C2H4, C2H6) with PAS technology, it provides complete diagnostic coverage at an attractive price point. The optional moisture sensor adds insulation condition monitoring to the gas analysis capability.
