Large Screen LCD Monitor Gas Chromatograph 500mm XHSP1700 with
User-Friendly Interface
XHSP1700 Gas Chromatograph This chromatograph has reasonable
structure design, atmospheric appearance, stable performance and
convenient operation. And loaded with the large-screen color
display technology independently developed by our company and the
unique network remote transmission and control functions, making
the instrument unattended, decentralized detection and centralized
control a reality. In addition, the instrument can also be equipped
with electronic flow controllers (EFC) and electronic pressure
controllers (EPC) according to customer needs, and one-key
operation function, which greatly improves the reproducibility of
analysis results and the level of automation, shortening The gap
between domestic models and imported models. The XHSP1700 power gas
chromatograph adopts the three-detector process recommended by the
national standard. It can complete the total content of the eight
components (H2, O2, CH4, C2H2, C2H4, C2H6, CO, CO2) of the
dissolved gas in the insulating oil with one sample injection.
analyze. The minimum detection concentration can meet the
requirements of the gas volume pair in the unit volume of oil when
the injection volume is 1mL: H2≤2ppm, C2H2≤0.1ppm, CO, CO2≤2 ppm,
qualitative repeatability: deviation ≤1%; quantitative
repeatability :Deviation≤3

Main Function
As we all know, the traditional electric gas chromatograph works by
a chromatograph, an AD converter, a set of computers and a set of
printers. This way of working makes it very inconvenient for users
who are equipped with more chromatographs to use and manage, and
there is a serious waste of repeated investment in equipment.
Aiming at the disadvantages of this traditional power gas
chromatograph, Xi'an Xuzhihui Electric Co., Ltd. uses its strong
technical development strength, adopts brand-new industrial models,
electronic circuits, and applies today's mainstream technology (IP
technology) to power gas phase.
Chromatograph, a new type of electric gas chromatograph developed.
The instrument abandons the discontinued chip, disassembled chip,
and the obsolete RS232 communication serial port. Instead, it
adopts a new and highly integrated industrial-grade chip, bus
technology, Ethernet technology, micro-flow gas control technology
and data processing technology, and optimizes The temperature
control program and gas path control fundamentally improve the
stability and maintainability of the instrument.
★ Advanced technology 10/100M adaptive Ethernet communication
interface, and built-in IP protocol stack, so that the instrument
can easily realize long-distance data transmission through the
enterprise's internal LAN and Internet; make the instrument
unattended, decentralized detection, and centralized control Become
reality;
★ Three independent connection processes are designed inside the
instrument, which can be connected to local processing (lab site),
unit supervisor, and superior supervisor, which can conveniently
enable unit supervisor and superior supervisor to monitor the
operation of the instrument and analyze data results in real time;
Manufacturer, can realize remote diagnosis, remote program update,
etc. (user license required);
★ The instrument is equipped with a 5.7-inch large-screen color LCD
screen; The keyboard operating system has two operating systems in
Chinese and English, which can be switched freely; to meet the
needs of different operators;
★ The instrument adopts a multi-processor parallel working mode,
which makes the performance of the instrument more stable and
reliable;
★ Automatic identification technology is adopted; it has fault
diagnosis and power-off data protection functions, and can
automatically memorize the set parameters;
★ The instrument adopts a modular structure design, which is clear
in design, easy to replace and upgrade, and protects the
effectiveness of investment;
★ Brand new The microcomputer temperature control system has high
temperature control accuracy, excellent reliability and
anti-interference performance; it has a six-channel completely
independent temperature control system, which can realize sixteen
steps of program temperature rise; it has an oven automatic rear
door opening system to improve the accuracy of low temperature
control. The temperature rise/fall speed is faster;
★ The instrument is designed with a timing self-starting program,
which can easily complete the online analysis of gas samples
(online automatic sampling components are required);
★ The instrument is equipped with the domestic mainstream
"transformer oil gas analysis workstation" with powerful functions
and operation Concise; and can realize remote control of the
chromatograph, such as modifying temperature control parameters,
realizing automatic ignition, adding/breaking bridge flow, air flow
control, etc.
★ The chromatograph has a built-in low-noise, high-resolution
24-bit AD circuit, and has the functions of baseline storage and
baseline subtraction;
