VQ546M
SGX Sensortech VQ546M — Gas
The SGX Sensortech VQ546M is a thermal conductivity gas sensor utilizing a Wheatstone bridge output with negative methane response to measure helium, hydrogen, and methane across a 0-100 % Vol range via diffusion flow. Built on the VQ500 head, this device type supports both portable and stationary deployment and carries ATEX certifications II 2G Ex d IIC Gb and I M2 Ex d I Mb for flameproof operation within a -40 to +55 °C temperature range.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued SGX Sensortech references — within one business day.
