Introduction

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), oxygen (O2) and combustibles (%LEL). The compact and field tough GasAlertMax XT IIfeatures 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.

Larger, User-Friendly LCD
GasAlertMax XT II is equipped with a high-definition LCD. The display shows all current conditions and advises the user when automatic functions are taking place. The alphanumeric LCD keeps you advised of any gas hazard present. The backlight illuminates automatically in low light conditions and in all alarm conditions. The backlight also activates on demand.
Audible/Visual Gas Alarms
Audible (95 dB) alarms and visual alarms activate, ensuring maximum protection. Visual alarms feature the unique wide-angled alarm bar and flashing screen icons that advise alarm level and type (LOW - TWA - HIGH - Multiple Gas). The LCD gas icon fl ashes to advise which gas hazard is present. 

In Low Alarm, the audible alarm sounds in a slow repeating pattern and the visual alarm LEDs fl ash in sync.
TWA (Time Weighted Average) and High Alarm conditions feature urgent, rapid audible/visual patterns. Alarm levels are field-settable.

Auto ON Functions
GasAlertMax tests all features and functions each time it is turned on, ensuring the instrument is ready for use. 
  • The sensors, battery and data card are tested.
  • The oxygen sensor is calibrated automatically
  • Current alarm set-points are displayed.
    All display elements, the backlight and audible/visual alarms are activated.
  • Current time, day and date are displayed on user-downloadable data-logger models (-DL2).
Automatic Sensor Calibration
Auto zero the sensors, at any time, without calibration gas. Calibrate one or all four sensors automatically. Simply apply gas when the flashing Auto Span icon lights.

GasAlertMax XT IItests the calibration gas applied. If the calibration gas does not meet expected parameters, the instrument exits Calibration Mode to prevent improper calibration. All the previous calibration data is retained.
High Efficiency Sampling Pump
GasAlertMax XT II is equipped with a high-efficiency, motorized sampling pump. The rotary vane design provides the benef ts of a small turbine - greater reliability with less friction - and the pump is not pressure sensitive. The detector will automatically advise if the pump or sampling hose is blocked.
   
Status at a Glance:
Information and guidance is
provided clearly and quickly
by the GasAlertMax: 

 

Alarm Advice: The alarm icons will light to advise the gas level and alarm type encountered: LOW, HIGH or TWA gas alarms.
TWA alarm overrides a LOW alarm, and a HIGH alarm overrides a TWA alarm.
Battery Level: The battery condition is continuously tested and displayed.
Data-logging Advice: The data card icon lights if the data card is present and functioning.
Auto Pump Re-Calibration: Sampling pump calibration is automatic.
 
Additional Features and Functions User Field Options
  • Two (2) levels of alarm for each gas sensed.
  • Low battery warning provides a 30-minute alert.
  • GasAlertMax cannot be accidentally shut off.
  • Missing sensor alarm advises which sensor is missing.
  • LEL sensor over range alarm protection.
  • Gas alarms take priority over all other alarms.
  • 2-year warranty on all sensors.
  • Field Upgrade 2 and 3-gas detectors can be upgraded in the field to a 3 and/or 4-gas detector.
  • Select any or all of the following:
    Con. dence Beep - the detector beeps every 5 seconds when selected on start-up.
  • Pass Code Protection - restricts access to calibration and alarm setpoints functions.
  • Latched Gas Alarms - Audible/Visual Alarms will continue to sound until the alarm is acknowledged.
  • Change Time and Date - change the time and date on
    user-downloadable detectors (-DL2) in the field if required.
