The NEW GasAlertMax XT II portable and multi-gas detector simultaneously monitors and displays up to four gases including hydrogen sulfide (H2S) carbon monoxide (CO), new 4-series oxygen (O2) sensor - SR-X10-C1 and combustibles (%LEL). The compact and field tough GasAlertMax XT II features a non-intrusive integrated sampling pump designed for performance, reliability and ease-of-use. SmartSample pump technology improves remote sampling result accuracy and ensures a consistent, uniform flow.

One-button operation guarantees ease of use even while wearing gloves. Tamper-proof, user adjustable options enable the instrument to be customized to suit your specific application. Confined space entry and remote sampling have never been so easy with new intelligent pump technology. Minimize pump blockages and improve remote sampling result accuracy. The GasAlertMax XT II is fully compatible with the MicroDock II automated test and calibration system.

New Oxygen O2 Sensor

The Max XT II uses the new and improved oxygen sensor SR-X10-C1 that lasts longer and ultimately helps reduce replacement costs and down time.

The older Max XT uses the SR-X-MC oxygen sensor and will not work with the new Max XT II gas detector released June 2010.*

* In the accessories list below, you will still see the older oxygen O2 sensor SR-X-MC listed as a sensor option. The SR-X-MC will only work with the older Max XT. We kept this sensor in the list because the part number for the Max XT II is identical to the Max XT and we want to make sure that customers looking for Max XT oxygen sensors could easily find it.
