LFE CONTHOS3 TCD Thermal Conductivity Meter Helium Gas Analyzer
State-of-the-art thermal conductivity gas analyzer! For measuring the high thermal conductivity of helium.
The LFE CONTHOS3 TCD is a state-of-the-art gas analyzer for online monitoring in process gas applications. It employs a thermal conductivity method and can be used for measuring helium and hydrogen gases. Additionally, by selecting the thermostat temperature of the detector and minimizing the mutual interference of gas components, it enables long-term stable analysis of H2 and noble gas binary and quasi-binary mixed gases. <Features> - Minimum measurement range: 0 - 0.5% - Maximum measurement range: 0 - 100% - Fast response time (T90): within 3 seconds - High corrosion resistance throughout the entire path from gas inlet to outlet - Responsiveness independent of gas flow rate - Collaboration with external gas detector channels to achieve interference correction for up to three gases - Temperature control from 50 to 180°C with a thermal conductivity detector (thermostat) - Reduction of operational costs due to long lifespan *For more details, please download the catalog or feel free to contact us.
basic information
Excellent specifications for binary or quasi-binary mixed gases in the low measurement range of 0-5000 ppm of He in N2. Special specifications with a minimum measurement range of 0-1000 ppm. Fast response time T90 of 3 seconds. High corrosion-resistant TCD cell made of Al2O3 and glass quartz, free of epoxy resin, compatible with process gases such as Cl2, HCl, H2S, SO2, and H2O. The entire path from the gas inlet to the outlet has high corrosion resistance. Low detection limit in the lower ppm range. Responsiveness independent of gas flow rate. Various functions for special cross-correction in non-binary compounds. Achieves interference correction for up to three gases in conjunction with external gas detectors' channels and analog inputs or serial interfaces. Temperature control from 50 to 180°C with a thermal conductivity detector (thermostat). Gas pathways can be controlled with a thermostat up to 180°C to avoid high dew points or the possibility of salting out. Reduction of operating costs due to long lifespan. Intuitive user interface based on NAMUR standards.
