Tetra 3

Référence : Tetra 3
Catégorie : Détecteurs Gaz Portables

Description : Conçu en pensant à l’utilisateur, l’écran de montage supérieur, les données complètes et les journaux d’événements, les alarmes sonores, visuelles et vibrantes offrent des performances de pointe dans un boîtier petit et léger.

Les gaz comprennent les quatre plus courants (monoxyde de carbone, méthane, oxygène et sulfure d’hydrogène), ainsi qu’une gamme élargie: ammoniac, ozone, dioxyde de soufre, monoxyde de carbone filtré à l’hydrogène (pour les aciéries) cyanure d’hydrogène, autres gaz inflammables et dioxyde de carbone IR ( pour une utilisation en zone sûre uniquement).

Gases and Ranges :

Ranges and alarms vary by country and application; these can be configured as required. Each channel can have two instantaneous alarms. Toxic channels also have TWA alarms. Flammable gas calibration is available for methane, propane, butane, pentane, hydrogen and ethylene as standard.

Gas Range Typical Alarms
Flammable  0-100% LEL  20% LEL
Oxygen  0-25% 19/23.5% volume
Hydrogen sulphide (H2S)  0-100ppm  5ppm
Carbon monoxide (CO)  1-500ppm 30ppm
Sulpher dioxide (SO2)  0-20ppm 1ppm
Ozone (O3)  0-1ppm 0.1ppm
Ammonia (NH3)  0-100ppm 25ppm
*Carbon dioxide (CO2)  0-5% 0.5 % volume

* T3 is available in a safe area CO2 version offering 0-5% carbon dioxide measurement.
The CO2 sensor replaces the flammable option and can be supplied with oxygen and toxic sensors.
