## BOC Series 8500 Helium Multi-Stage Regulator – 2 Gauge

The **BOC Series 8500 Helium Regulator** is a multi-stage regulator designed for accurate and stable helium pressure control. It is ideal for specialist applications such as **gas chromatography**, where helium is commonly used as a carrier gas, as well as meteorological surveying and other precision helium supply requirements.

The Series 8500 range is available in **10 bar** and **4 bar** versions. The 10 bar regulator is suitable for higher delivery pressure applications, while the 4 bar version offers the same key benefits with an easier-to-read scale for lower pressure use.

With a multi-stage design and twin gauges, this regulator provides consistent delivery pressure and clear monitoring of both cylinder contents and outlet pressure. It is a reliable choice for laboratory, technical and specialist gas applications.
