Transformer Oil DGA Dissolved Gas Chromatography Analyzer

HZGC-1212A Transformer Oil DGA Dissolved Gas Chromatography Analyzer

Features of HZGC-1212A Gas chromatograph:

★ It adopts advanced technology of 100Mbps/1000Mbps Ethernet communication interface and built-in IP protocol stack, enabling the instrument to achieve long-distance data transmission through the enterprise's internal LAN and the internet; facilitating laboratory setup, simplifying laboratory configuration, and convenient data management.

★ The instrument is internally designed with three independent IP addresses, which can be connected to the workstation (at the laboratory site), dedicated computers (such as quality inspection department, production department), and executive computers (such as environmental protection bureau, technical supervision bureau). Real-time monitoring of instrument operation and analysis data results is possible.

★ The dedicated workstation equipped with the instrument can simultaneously support multiple chromatographs for data processing and instrument reverse control, simplifying document management.

★ The instrument can be connected to the manufacturer via the internet, enabling remote diagnostics, remote updates, etc. (user configuration required).

★ The instrument is equipped with an 8-inch color LCD touchscreen, supporting hot swapping and can be used as a handheld controller.

★ The instrument operates in parallel with multiple processors, making it more stable and reliable. It can be optionally equipped with a variety of high-performance detectors such as FID, TCD, ECD, FPD, and NPD, with a maximum installation of three detectors simultaneously to meet the analysis requirements of complex samples.

★ The instrument adopts a modular design structure, making it easy and convenient for maintenance.

★ The new microcomputer temperature control system provides high temperature control accuracy, superior reliability, and anti-interference performance. It has eight completely independent temperature control outputs, enabling sixteen-step program heating. It also features an automatic back-opening system for the column oven, improved near-room temperature control capability, and faster temperature ramp rates.

★ The chromatograph has a built-in low-noise, high-resolution 24-bit AD circuit, with baseline storage and subtraction functions.

★ The standard workstation is suitable for operating systems such as WinXP, Win2000, Win7, Win8, Win10.

★ The chromatograph's microcomputer system with fully independent intellectual property rights has the standard MODBUS/TCP protocol and can be integrated with DCS systems.
