Sensors

• Filter Saturation Detection: A dual sensor system, this exclusive and innovative detection includes a sensor for the filtration system and the ambient air quality. The first sensor is located between the main filter and backup filter. A second sensor is set outside the hood to monitor ambient air quality of the entire laboratory setting.
• Temperature Sensor: Sensitive to unusual temperature fluctuation, this sensor sets off audible and visible alarms. This sensor is also synchronized with gGuard monitoring software to send a remote alert via network. Temperature sensors are also a dual sensor system. The first alarm is activated when the temperature remains steady at 176° F. The second sensor goes off when the internal fume hood temperature reaches 212° F.
• Sash Position and Airflow Detection: This system of sensors works to automatically adjust the blower speed to ensure a face velocity of 100 fpm based on the height of the sash opening. This system can be monitored and managed by gGuard online software.
• User Identification System: An optional personalized RFID card may be used to operate the hood. The Radio Frequency Identification card is programmed with personal information and allows a specified level of access. The three levels of access include: User — allowing full operation of the hood; Administrator — access to recorded data on the hood such as usage and alarm history; and Maintenance — total access level allowing calibration functions and access to other features for service and repairs.
