Gasman
Référence : Gasman
Catégorie : Détecteurs Gaz Portables
Description : Le Gasman est un détecteur mono-gaz personnel compact et robuste conçu pour les environnements les plus agressifs.
Résistant aux chocs et conforme à IP65, le Gasman permet la détection d’une large gamme de gaz, avec notamment six options d’étalonnage de gaz inflammables.
Le Gasman dispose d’une combinaison imbattable d’alarmes sonores et visuelles puissantes.
Grâce à sa conception remarquablement compacte et légère, il est idéal dans des industries telles que le pétrole, le gaz, la chimie, la métallurgie et la gestion de l’eau et des déchets.

*Operating time will depend on operating pattern and alarm occurrence. Frequent or long lasting alarms and use of the optional confidence beep will reduce battery life.
**Toxic and oxygen sensors are not rated for continuous operation at high temperatures. Consult Crowcon if operating temperatures are likely to exceed 40°C (104°F) for extended periods.
Gases and Ranges :
Required ranges and alarms vary by country and application and these can be configured as required. Each gas channel can have two instantaneous alarm levels set. Toxic units also have Time Weighted Average (TWA) alarms.
Flammable gas calibration is available for methane, propane, butane, pentane, hydrogen and
ethylene as standard.
Gasman is also available in a safe area CO2 version offering 0-5% carbon dioxide measurement.

| Carbon monoxide (CO) | 0-500 ppm | 30 ppm |
| Carbon dioxide (CO2) | 0-5% vol. | 0.5% vol. |
| Chlorine (Cl2) | 0-20 ppm | 0.5 ppm |
