Mobile Gas Detector Polytector III G999C/5 with Pump – for Entry and Clearance Measurement
The portable gas detection device Polytector III G999C/5 from GfG
Made in Germany: The Polytector III G999C/5 is a robust and high-performance multi-gas detector with an integrated pump. It has been specially developed for use in wastewater and sewer applications and enables the simultaneous monitoring of up to five gases. Whether for manhole entry, pre-entry clearance measurements, or maintenance work – this multi-gas detector delivers reliable safety.
Product Features
- Simultaneous measurement of up to 5 gases: flammable gases (LEL – CH4), CO2, CO, O2, H2S
- Integrated pump: For active sampling – ideal for work in manholes and confined spaces
- ATEX explosion protection: Suitable for Zone 1 and Zone 2 applications
- Protection class IP67: Dustproof, waterproof, and shock-resistant – perfect for harsh working conditions
- Large display & intuitive operation: Clear display, rotatable by 180°, user-friendly 3-button menu navigation, incl. LED flashlight
- Long battery life: Up to 130 hours in diffusion mode, approx. 20 hours in pump mode
- Multifunctional alarms: Audible, visual, and vibration alerts – includes man-down alarm in case of immobility
- Alarm simulation: Simulate hazardous scenarios for training purposes
- Data logger: Stores up to 30,000 readings, 12 values simultaneously
- PEAK function: Displays peak gas values
- Optional accessories: Can be extended with sampling hose and floating probe – essential for clearance measurements and measurements over liquid surfaces
Practical Benefits
- Reliable personal protection: Early gas detection saves lives during sewer and maintenance operations
- Man-down alarm: Two-stage local warning in case of immobility
- Strong warning functions: Audible, visual, and vibration alarms – effective even in noisy environments
- Fast clearance testing: With pump and sampling hose, sewer clearance measurements can often be completed within one minute
- Practical design: Operable with gloves, even in wet and dark environments
Typical Applications
- Pre-entry gas testing in sewers, manholes, and wastewater shafts
- Pumping stations, wastewater treatment plants, biogas facilities, and other ATEX zones
- Industrial applications in chemical plants, utilities, and gas supply networks
- Rescue and safety services during incidents and emergency operations
Important Note
To perform clearance measurements with the Polytector III G999C/5, a sampling hose (available separately) is required. For measurements over liquid surfaces, a floating probe is also available as an accessory. Without the sampling hose/floating probe, the device can only be used for direct point measurements – not for clearance testing.
Which device is right for your application?
The Polytector III G999C/5 is the first choice for manhole entry, clearance measurements, and demanding applications with active sampling – thanks to its integrated pump.
Looking for a compact and lightweight device for routine sewer and manhole work without a pump? The Microtector III G888C/5 is the perfect solution – note: not suitable for clearance measurements.
