Portable PPM Oxygen

The Ntron Model 7100P is an affordable solution that’s ideal for spot-checking of high-purity applications.  Multiple analog and RS-232 outputs provide flexibility and the unit is ready to use after only a 2-minute warm-up.

The 7100P is provided with a pump for sampling of gas streams. The flow meter indicates the rate of the sample through the pump and into the analyser.
