XP 302II |
FEATURES
- Detects ans alerts to concentration of Oxygen, combustible gas (methane), hydrogen sulfide and Carbon monoxide
- The internal microprocessor has the following functions and alerts workers by buzzer and lamp and gives messages.
- Performs various kinds of self-checks.
- circuit malfunctions
- various sensor malfunctions
- suction flow malfunction
- battery life
- improper connection to external alarms.
- Each time the power switch is turned on the pump is automatically switched is turned on the pump is automatically switched and each sensor is calibrated.
- This instrument incorporates a large liquid crystal display model to display messages quickly and accurately. Operates from dry cell batteris, 100VAC or 220 VAC through an adptor. Battery life has been considerably lengthened through the new energy saving design. Designed to explosion proof specification and can be use in hazardous areas. (except when being used with the AC adaptor) Drip-proof construction. Case included Ambient temperature of the work area is measured. Peak level of the subject can be measured. Various optional accessories available. If an output device such as a printer is connected, gas concentrations are automatically recorded Automatic display illumination permits easy use in the dark.
