Honeywell Searchzone Sonik is an Ultrasonic gas leak detector that senses the sound generated by high-pressure gas leakage at the source. Suitable for use in hazardous areas.  Traditional point detectors or Open Path units will not pick up leaks unless gas comes into contact with the sensor. In an outside environment, these leaks can be dispersed by wind and go undetected. The Honeywell Searchzone Sonik is not affected by weather conditions, but background noise can affect radius. General radius 20m (65 ft). The sensitivity of the detector can be increased to combat background noise interference, thus avoiding false alarms.

For commissioning and configuration use Bluetooth on a hazardous area approved mobile device, a testing tool assists set up at ground level, removing the need to work at height, save time, and ensure safety in harsh weather conditions. The universal mount allows wall, pole and strut mounting with alignment adjustment. To assist installation angled cable entries: 2 x M25 or 2 x ¾ NPT and plugin terminals are provided isolated from the sensor components.

The Searchzone Sonik does not require any calibration as it is fitted with a solid-state sensor, in combination with no moving parts allows deployment in the harshest of environments.

Operation in Normal mode gives wide-angled detection suitable for areas with low background noise. Switching to Focus mode engages special algorithms that combat background noise coming from areas not of interest.
