The NEW GasAlertMicroClip XTportable and multi-gas detector simultaneously monitors and displays up to four gases -hydrogen sulfide (H2S) carbon monoxide (CO), oxygen (O2) and combustibles (%LEL). The compact and field tough GasAlertMaxClip XT is similar to the MaxXT but without the integrated sampling pump. Designed for performance, reliability and ease-of-use. 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
GasAlertMicroClip XT 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
GasAlertMicroClip XT 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 tests 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.
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.
