Multi-function Oscillation Tester BLS-429
【Brief】:The instrument complies to the oscillating degassing method GB/T17625-1998.
【Series】:Insulating Oil Transformer Oil Testers


The instrument complies to the oscillating degassing method GB/T17625-1998 Gas Chromatographic Method for Dissolved Gas Content in Insulating Oil, and oscillating heating method DL429.4-91 Quantitative Measurement Method of Water Soluble Acid.


The instrument is mainly used for oscillating degassing in gas chromatography of insulating oil, oscillating operation in water-soluble acid determination method (colorimetric method) in oil, and can also be used for constant temperature, timing and oscillating operation in other physical and chemical tests. The instrument has automatic temperature control, timing, static and alarm prompts. It has fast heating, accurate temperature control, beautiful structure and simple operation. The oscillation control performance is good and the noise is extremely low.
