Leak detector Polaris
Ultralow methane concentrations detection
Low-cost and easy-to-use alternative to laser-diode gas detectors
Features
Functionality
Gas detectors Polaris are designed for ppm methane leakage detection outdoors and output alarms in excess of the measured the value of the threshold.
Application Scope
- monitoring of long-distance main gas pipelines, low-pressure gas pipelines, city gas communications and other facilities
- methane leaks detection in problem areas (at locking groups, at the intersection of gas pipelines with various transport routes, etc.)
- early stress gas pipe corrosion detection
- streets, cities’ districts and industrial enterprises environmental monitoring
- man-made accidents and environmental disasters early warning
Trace methane gas detector Polaris comes in two possible modifications:
Intended for mobile laboratory vehicles for monitoring methane leaks from underground city gas mains. Gas detector is designed as a stationary device. Set in mobile laboratory vehicles for monitoring methane leaks from underground city gas mains. A powerful sampling equipment, which limits the ingress of air samples from the outside, is mounted between the car wheelbase and connected to the Polaris, which is located in a special box behind the driver’s seat. The car moves at a speed of up to 40 km / h, and the device shows the measured concentration, processed according to a special algorithm that records only a sharp increase in concentration. This signal processing algorithm eliminates the influence of changes in the background methane concentration in the city and only real leaks are recorded.
Specifics
- external forced sampling at rate of up to 8 l/min
- nozzle diameter 12 mm
- response time 0,5 seconds
- resolution is 0.1 ppm at indications ranging 0 ÷ 999 ppm, and 1 ppm at indications ranging 1000 ÷ 9999 ppm
- can be powered from the vehicle’s on-board network (12 W)
- built-in battery
- received data is displayed on the operator’s on-board monitor
Portable gas detector designed to control ultra-small leaks from open gas pipelines in the air of populated areas and non-explosive areas of industrial facilities.
Specifics
- small size and weight compared to this class devices
- bright dial indicator for visual identification of leaks
- built-in pomp at rate of up to 0,5 l/min

- response time 4 seconds
- resolution is 0.1 ppm at indications ranging 0 ÷ 999 ppm, and 1 ppm at indications ranging 1000 ÷ 9999 ppm
- sound alarm upon reaching the set threshold
- built-in battery operating time > 4 hours
