Nitrogen-Hydrogen-Air Integrated Machine, NHA-500 (CAT#: STEM-GLE-0104-ZJF)

The NHA-500 integrated machine offers the same features as the NHA-300, with a stainless steel gas storage tank, four stainless steel filters with trace oxygen removal, and low-sulfur silicone rubber seals to ensure no impact on detectors. The compact and convenient structure allows for full automatic operation and reliable safety, suitable for any brand and model of gas chromatograph. The nitrogen section includes automatic anti-backflow and automatic flow tracking, the hydrogen section includes automatic anti-backflow and automatic flow tracking, and the air section features high-precision pressure stabilization, automatic water drainage, and comprehensive protection measures.
