ION Science ARA H2S is a wearable disposable single-gas detector for personal hydrogen sulfide (H₂S) monitoring. It is designed to alert the wearer when H₂S concentration reaches configured alarm levels; model life, alarm settings and application suitability must be confirmed before quotation.
Key Features
- Wearable clip format for breathing-zone personal monitoring.
- Electrochemical H₂S sensing with live readings.
- Visual, audible and vibrating alarms.
- Daily self-test and configurable reminders.
- Event logging and IR-Link data-management option.
- Disposable operating-life options according to model configuration.
Applications
- Personal H₂S monitoring
- Confined-space work and entry support
- Plant shutdown and turnaround work
- Oil and gas, water and process-industry maintenance
Specification Summary
Sensor range, operating life, hibernation option, approvals, operating limits and alarm settings depend on the selected ARA model. Confirm the required model and calibration/bump-test process before quotation.
What It Solves
The ARA H₂S helps alert an individual wearer to potentially unsafe H₂S levels during defined monitoring activities. It does not by itself establish regulatory compliance or replace a site-specific risk assessment, respiratory-protection programme or qualified safety advice.
