  • ToxiPro Single Gas Detector by Honeywell Analytics

    RAE ToxiPro single sensor portable gas detector by Honeywell Analytics

    The field replaceable ToxiPro® single-gas detector from Honeywell Analytics has three visual alarm windows that come standard with both high visibility yellow (warning) and red (danger) alarm LEDs that flash and chase. New enhancements for the IQ Management System provide automated email alerts so you and your entire group are in control by knowing instantly what alarms are occurring and more specifically, with customisable settings, only the alarms that are important to you.

    You can rest assured that should an incident occur you will know who was wearing the monitor, what work area they were in, when the event took place and what type of alarm event they experienced. Incident investigation time is now reduced with more detailed information about the alarm.

    It's simple one button automatic calibration enhances easy user operation.
