HIGHLIGHTS:

• High display resolution (0.01 % O₂ concentration)
• Waterproof and durable (protective silicone case)
• Large double display with background lighting
• Multi-point calibration for precision measurements
• Environmental pressure compensation with integrated barometer
• Alarm function

APPLICATION:

Protective gas measurements for

• Welding and soldering
• Food production/packaging technology (MAP, see also the Resox 5695-H / -L)
• For storage of foods, semiconductor components, etc.
• Immersion gas testing: Checking of oxygen concentration in nitrox, trimix or similar gas compositions

Note:
Not suitable for use in 'underwater applications' (rebreather, etc.)
