Searchzone Sonic Ultrasonic Gas Leak Detector by Honeywell
Honeywell Searchzone Sonic
The Searchzone Sonik Ultrasonic Gas Leak Detector by Honeywell complements an established portfolio of gas detection devices, adding ultrasonic technology to a reliable mix of point and open-path gas detectors.
Thanks to its robust sealed solid-state sensor that doesn’t need calibration and can withstand the harshest weather conditions, the Searchzone Sonik Ultrasonic Gas Leak detector delivers reliable gas leak detection, even in the noisiest environments, prevents false alarms, and reduces the cost of ownership.
A sophisticated App on a hazardous area Bluetooth device delivers remote access for set-up, interrogation and maintenance, supported by an advanced test-tool enabling testing from the ground – no need to work at height.

Precision Safety is a supplier of a wide range of Fixed Gas Detection or Permanent Installed Detectors in Australia and New Zealand. We supply stand-alone detectors and monitors as well as gas detection controllers integrated into plant PLC and control systems.
The Hazard is Blowing in the Wind
Field studies have shown that around 30% of flammable gas leaks can go undetected because the gas is blown away by the wind. But if the weather conditions change, and the wind drops, the chances are that a flammable gas cloud might build up and trigger incidents and hazards.
Why the Honeywell Searchzone Sonik Ultrasonic Gas Leak detector is the right choice...
How do you sense what you can’t hear?
Since gas does not need to come into contact with their sensors, ultrasonic (or acoustic) detectors respond instantly upon “hearing” the distinct sound pattern of a leak, operating at a frequency outside the range of human hearing. Unaffected by airflows and adverse weather conditions, they are particularly suited to open and well-ventilated areas, such as floating production storage and offloading vessels, gas turbine power plants, compressor stations, gas storage facilities, petrochemical processing plants, refineries, or offshore and onshore oil and gas installations.
A robust and reliable gas-leak detection device, Searchzone Sonik will efficiently “hear” the loss of containment of any high-pressure gas within its listening zone. As it responds to the ultrasonic sound pressure level produced by pressurized gas leaks, it is therefore unaffected by environmental conditions.
Searchzone Sonik is factory calibrated. Its robust sealed design with no moving parts and the advanced solid-state sensor allow for mounting in any orientation, even in the harshest environments. The acoustic gas leak detector will respond quickly to a gas leak within a sensing range radius of typically 20m, dependent upon background noise.


Key Features of the Searchzone Sonik Ultrasonic Gas Leak Detector
No False Alarms – the high-end spectral analysis delivers best-in-class detection of high-pressure gas leaks in real-world environments.
Wide Zone Coverage – typically 20m (65 ft) detection radius, dependent upon background ultrasonic noise levels.
Complements Existing Gas Detectors – the Searchzone Sonik seamlessly integrates with existing point-and-open path gas detectors, thus creating the optimal gas detection mix.
No Moving Parts – the solid-state sensor works flawlessly even in the harshest environments and doesn’t need additional calibration.
Simple Installation and Alignment – the Platform Universal Mount with 3 graduated degrees of freedom enables easy mechanical set-up.
Bluetooth Compatibility – set-up and interrogation from ground level are available via Bluetooth by using the Honeywell Platform application on IS mobile phones. Depending on the mobile device, the range can reach up to 20 m (65 ft).
Instrument Status at a Glance – the Searchzone Sonik features a bright signal light – green, yellow, red, or blue – providing clear indication of the instrument status.
Full Operational Logs – enables post-event analysis to assess overall performance and allows security checks.
Fast Commissioning – the Searchzone Sonik App allows users to save configurations and upload to other Searchzone Soniks for quick and easy commissioning.
