HCGC-180 Portable Chromatography Instrument for Gas Analysis in Transformer Oil

Detailed introduction:

HCGC-180It is a portable specialized chromatograph newly launched by Shenzhen Huachang Haitai Technology Co., Ltd. for rapid on-site analysis. The instrument adopts the classic three detector process and can complete the dissolution of insulating oil in one injection7Full analysis of gas component content (includingH₂、CO、CO₂、CH₄、C₂H₄、C₂H₆、C₂H₂）The analysis data is completely consistent with traditional laboratory chromatography data.The instrument adopts advanced technologySmall modular designThe design concept is small in size and light in weight, making it easy to carry to the site for analysis. It is the best choice for large transformers that require on-site tracking and testing in case of abnormalities.

■ Features:

★Using computer reverse control technology to achieve instrument gas path pressure（Carrier gas, hydrogen gas, air) passing through the workstationDigital display

★Using computer reverse control technology to achieve instrument temperature（Including column boxes, detectors, converters, etcSettings, display, and other operations

★ Using computer reverse control technology,Click the mouse through the workstationRealize one click startup

★digitizeFIDElectronic zeroing technology enhances the anti-interference ability of instruments

Using electronic zeroing technology to achieveFIDElectronic regulation of output signal level. Due to the fact that electronic adjustment can be directly installed on the signal channel of the circuit board, the electronic noise suppression capability is improved, and there is no interference signal when connecting mechanical potentiometers. Due to the reduction of parasitic parameters, it has strong anti-interference ability.

★Using computer inverse control technology to achieve control of the oscillator

HCGC-180Provide power to a small oscillator through a connecting signal line, and operate the entire process of the oscillator, including temperature rise, starting oscillation, stopping, and beeping at the end, through a workstation

★Built in silent air pump, no need for external air source

HCGC-180The host comes with an imported small air pump that can provide uninterrupted air supply for the instrument. Due to its shockproof design, the air pump can work silently, and users will hardly feel its presence.

★ Thermal conductivity tungsten wire gas cutoff protection function

HCGC-180Equipped with intelligent thermal conductivity cut-off protection function, when the carrier gas pressure is below the safety threshold, the system will automatically cut off the thermal conductivity current to protect the thermal conductivity detector from damage.
