TWA resume function:

  • Only available with the T4 Crowcon handheld gas analyzer, the TWA Resume function ensures that toxic gas exposures are accurately calculated throughout the entire shift, even when the T4 is turned off for rest or while traveling to a other system.
  • When most portable detectors are turned off, the TWA exposure assessment algorithm assumes that is the end of the case. When turned back on, these detectors act as if it were a new shift, ignoring all previous measurements. However, the TWA Resume function provides the option to include previous measurements in the exact timeframe.

18 hours battery life:

  • With a battery life of 18 hours, the T4 portable gas analyzer allows multiple shifts or longer to be worked on between charges.

Positive safety:

  • Crowcon T4's visual 'traffic light' markings provide ongoing visual assurance that the T4 is in good working order and in compliance with the system's risk checking & calibration policy. Positive green and red safety LEDs are visible to all and provide a quick, simple and comprehensive indication of monitor status to both the user and others around them.
