CrowconT4X

Details

The Crowcon T4x Portable Multi-Gas Detector is Crowcon’s Zone 0 approved personal protection solution for detecting the four most common gas hazards: carbon monoxide, hydrogen sulphide, flammable gases and oxygen depletion, offering you compliance and low cost of ownership in one simple-to-use solution.

The T4x has three sensor technology options for you to select according to your needs: Dual Toxic sensor for CO and H2S, Long-Life Oxygen (LLO2), and the MPS™ sensor, which has zero risk of device poisoning and can accurately identify over 15 different flammable gases in one device.

The large single button and intuitive menu system allows T4x to be operated wearing gloves with minimal training, and it is durable by design and includes an integrated rubber boot as standard, with all the durability you can expect from the T4 range. Plus, its 35+ hour battery life (double the battery life of our original T4) allows multiple or longer shifts to be worked between recharging, allowing for uninterrupted working in the most demanding environments.

MPS™ (Molecular Property Spectrometer) Technology:

▪ No calibration or scheduled maintenance is needed, reducing interruptions and increasing uptime
- ▪ Sensor self-monitors every 2 seconds, automatically reporting any problems with its operation
- - ▪ ‘True LEL’™ multi-gas accuracy means it can accurately detect multiple gases at once and instantly identify the gas type
  - - ▪ No sensor ‘poisoning’ from environmental toxins or contaminants, providing uncompromised performance
    - - ▪ Hydrogen ready sensor
      - LLO2:
        
        ▪ Long-life O2 (LLO2) provides oxygen detection with an industry-leading 5-year warranty
        
        ▪ Lead-free for RoHS compliance and reduced environmental impact
        
        ▪ While standard O2 sensors need replacing every 2 years, our 5-year long-life sensor helps reduce the cost of ownership
        
        TWA Resume:
        
        ▪ The TWA Resume function can measure toxic gas exposure over a whole shift, even if switched off, using previous measurements from within the correct time frame
        
        ▪ TWA Resume means you can track exposure across multiple sites without requiring continuous use
        
        ▪ Option to include previous measurements from within the correct time frame can be switched on or off, for optimal performance
        
        Reliable:
        
        ▪ 35+ hours battery life, double the battery life of our original T4, allows multiple/longer shifts to be worked between recharging
        
        ▪ TWA Resume means you can switch off the device to save battery charge, without losing recent data readings for hassle-free regular use
        
        ▪ ‘Traffic light’ indicators provide constant visual assurance the device is operating soundly
        
        ▪ Conforms to site bump test & calibration policy for constant assurance
        
        ▪ The bright green and red ‘Positive Safety’ LEDs allow for instant, intuitive signal interpretation
        
        ▪ Zone 0 certified, so it’s safe to use in even the most hazardous environments
