What We Do

Hexisense makes gas sensors for vacuum systems based on gallium nitride semiconductor chips. Our first product, OxyGaN, is capable of measuring total pressures from 1 to 1E-5 mbar at the same time as oxygen partial pressures from 0.1 to 5E-7 mbar, even in the presence of a background gas.

Nothing like this tiny chip exists on the market today, but you can think of it as a pressure gauge combined with a single-channel residual gas analyzer: you measure pressure and safeguard against unwanted air leaks or contaminated gas lines while your live vacuum process is running, but without breaking your budget.
