The MODEL5000 Series is an online hydrogen transmitter for purity and concentration measurement using solid-state palladium-alloy thin-film sensing technology. It measures hydrogen from 0 to 100% vol and is designed to remain selective in the presence of gases such as CO and H2S. Published accuracy is ±0.3% vol from 0–10% hydrogen and ±1% vol from 10–100%, with response in under 30 seconds. The transmitter supports 4–20 mA, RS232, RS485 and Modbus RTU interfaces and is specified with IP67 protection.
Hydrogen Sense Technology Co., Ltd. develops and manufactures palladium-alloy thin-film hydrogen sensors, transmitters and online analyzers. Its manufacturing capability includes MEMS thin-film sensor-chip design, fabrication, packaging and test equipment, with dedicated hydrogen-sensing products for hydrogen production, storage, transport, fuel-cell and industrial gas-monitoring applications.
