F12D Toxic Gas Detector
Brand: Analytical Technology Inc/F12-Toxic-Gas-Detector/488546_F12_Toxic_Gas_Detectors_2.gif)
ATI's F12iS Toxic Gas Detector is designed to measure toxic gases and oxygen in hazardous locations requiring an Intrinsically Safe (IS) device.
The F12/D, a non-IS version, is also available for non-hazardous locations.
For many toxic gases, ATI offers a unique sensor response testing system unmatched by any competitive gas transmitter.
Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to ensure system integrity.
Sensor response is verified with an actual gas sample that is generated on demand.
Generators store run time information accessible to operators, and are automatically tested for compatibility with the installed electrochemical sensors.
F12 gas detectors provide useful features that simplify installation, operation, and maintenance.
The 4-button keypad is used to configure the menu-driven setup pages.
The display also provides alarm indication and complete menus for setting up operating parameters.
Each version utilizes a digital communications protocol. The IS version of the gas transmitter is available with HART™ communications.
The HART™ protocol supports the HART™ Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard.
The non-IS version of the transmitter is available with MODBUS™ communications.
The MODBUS™ protocol supports 9600 baud access to concentration and status information, and supports alarm setup and many other functions on either RS485 or RS232 (software selectable).
