Low / High SO2 alarms
ARA SO2 Single Gas Detector
Portable Gas Detector from ION Science
ARA SO2 is a portable, disposible single gas detector that provides instantaneous alarms for life critical safety scenarios.

About ARA SO2 Single Gas Detector
ARA SO2 gas detector is a cost effective personal sulfur dioxide detector with 24 months of continuous operation. This wearable SO2 gas detector has only one button to make using the SO2 gas detector simple and alerts workers when SO2 health levels exceed set safety levels.
* All specifications quoted are at calibration point and under the same ambient conditions.
The ARA DOCK4 is a bump test and calibration station that can test up to 4 ARA Single Gas Detectors simultaneously reducing gas usage and testing time. The ARA DOCK4 is simple to operate and records calibration and bump test reading along with the serial number, date and time.
