Ion Science ARA — Disposable Single Gas Detector (H2S, CO, O2, SO2) Gas:O2 Standard (ARA300) DO and nitrate sensors lastIon Science ARA Single Gas Detector The Ion Science ARA is a wearable, intrinsically safe single gas detector built around a maintenance free ownership model: single button operation, no sensor changes, no calibration program, and a two year service life from activation. For fleets of workers who need reliable personal gas protection without the overhead of a docking, bump test, and calibration regime, the ARA is a substantially lower total cost
