High-precision measurement with 99.999% display - LFE Hydrogen Gas Analyzer
It is a state-of-the-art thermal conductivity hydrogen gas analyzer! It has a very high precision display of 99.999%, and in digital communication, it displays 99.99999%.
The LFE CONTHOS3 TCD is a state-of-the-art thermal conductivity hydrogen gas analyzer for online measurement. It employs a thermal conductivity method and can be used for measuring hydrogen gas and helium gas. Additionally, by selecting the thermostat temperature of the detector and minimizing the mutual interference of gas components, it can stably analyze two types of mixed gases, such as hydrogen gas, over a long period. <Features> - Minimum measurement range: 0 - 0.5% or 99.5 - 100% H2 in N2 - 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 50-180°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 with H2 in N2 at a low measurement range of 0-5000 ppm. Special specifications with a minimum measurement range of 0-1000 ppm. Very high control range, such as 99.5-100% H2. Fast response time T90 of 3 seconds. High corrosion-resistant TCD cell made of Al2O3 and glass quartz, free from epoxy resin, compatible with process gases such as Cl2, HCl, H2S, SO2, and H2O. High corrosion resistance throughout the entire path from gas inlet to outlet. 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 collaboration 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 path can be controlled with a thermostat up to 180°C to avoid high dew points or the possibility of salting out. Reduction of operational costs due to long lifespan. Intuitive user interface based on NAMUR.
