C4F7N Mixing Ratio Tester, C4F7N,CO2,O2, Moisture Content
KS31-C4-4 C4 Mixing Ratio Tester (C4F7N:CO2:O2:dewpoint)
C4F7N abbreviated as C4
The C4 comprehensive tester is a specialized testing tool that integrates C4humidity,C4 concentration, CO2, and O2.
The excellent performance of the C4 gas comprehensive tester is due to the use of the best foreign sensors; Humidity is measured using Finnish Vaisala, C4 and CO2 are measured using infrared sensors, and O2 is measured using electrochemical sensors;
When needed, decomposition products can be stacked and combined to form a C4 mixed gas comprehensive tester, with imported sensors used for decomposition products.
The instrument adopts a color LCD display, which displays various parameters in real time, with a foolproof operation throughout the process, massive information storage, built-in rechargeable battery, and dual-use of AC and DC.

About C4
3m-novec-4710-insulating-gas
Introduction
3M™ Novec™ 4710 Insulating Gas is a sustainable alternative to sulfur hexafluoride (SF6) for electrical equipment
insulation and arc quenching applications. It offers excellent dielectric properties, a wide range of operating
temperatures and significant reductions in environmental impacts compared to SF6. Novec 4710 gas is non-
flammable and has a wide safety margin for workers when used as designed for intended applications. This
SF6 alternative also has important environmental properties such as low global warming potential (GWP) when
mixed with inert gases and zero ozone depletion potential (ODP). Novec 4710 gas in pure form has a relative
dielectric strength two times greater than SF6 at a given pressure.
The current manufacturing enterprises in China include: Yuji, Hexafluo, and Haohua; yuji;
On December 20, 2022, 3M announced that it will cease production of 58 Per/polyfluoroalkyl substances (PFAS) products, including perfluoroisobutyronitrile (C4F7N, 3M Novec 4710) and perfluoropentanone (C5F10O, 3M Novec 5110), by the end of 2025 to reduce or eliminate the impact of PFAS on climate, environment, and ecological health.
Application scenarios of C4 gas in ultra-high voltage electrical systems:
In recent years, numerous ultra-high voltage enterprises in China have been conducting research, testing, and experimentation on the application of C4 for many years, mainly including as China Xidian, Changgao, Ankura, and Shenma.International brands include GE and Siemens Energy;
KSTONE is a leading enterprise in China that develops C4 and C5 related instruments and equipment;and has precise cooperation with 3M and chinese C4 or C5 manufacturers ;
