DE-OX SUN Helium Analyzer with Alarm
DE-OX SUN represents the simplest and up-to-date measurement instrument for the analysis of helium into mixed gas. Unique features include two audible alarms (minimum and maximum), standard analog 4-20 mA and open collector outputs.
DE-OX SUN represents the simplest and up-to-date measurement instrument for the analysis of helium into mixed gas. Unique features include two audible alarms (minimum and maximum), standard analog 4-20 mA and open collector outputs. DE-OX SUN has been especially designed and manufactured for the analysis of binary and ternary gas mix like heliox and trimix.
The instrument does not require calibration. DE-OX SUN can be used for continuous reading during mixed gas filling. It can alert and help in switching off the compressor if the helium value goes out the set alarms range (for instance 45% helium). DE-OX SUN is based on an innovative sensor developed by TEMC for respiratory use and for monitoring the respiratory parameters in saturation dives.
