Product Features
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 overawhole 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
