F12iS Toxic Gas Transmitter

ATi’s F12iS Toxic Gas Transmitter is the perfect choice for detection of gas leaks in explosion-hazard environments, while operating at intrinsically safe power levels.

Intrinsically Safe gas detector

ATi’s F12iS Toxic Gas Detector is designed to measure toxic gases and oxygen in hazardous locations requiring an Intrinsically Safe (IS) device. While operating at intrinsically-safe power levels, the F12iS is also available with our exclusive Auto-Test* feature that verifies sensor function daily, virtually eliminating the need for manual bump-tests.

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.

The F12/D, a non-iS version, is also available for non-hazardous locations.

Smart sensors

The F12iS uses ATi smart sensors that allow easy interchangeability. Each sensor contains signal conditioning electronics and data memory. Sensors can be calibrated using a spare unit avoid using calibration gases in the plant. Sensors may also be returned to ATi for factory calibration, which is useful for gases that are costly or difficult to obtain. Each sensor adjustment (zero or span) is stored in sensor memory and can be reviewed on the F12iS display. This data is very useful in assessing the sensor’s condition and estimating remaining sensor life.

Frequently Asked Questions

How often should you calibrate the ATi H10 smart gas sensor?

We recommend that the H10 smart gas sensor is calibrated every 6 – 12 months, however this may vary depending upon which gas is being monitored.

Can I use one ATi H10 smart gas sensor in multiple devices?

Yes, the ATi H10 smart gas sensor can be plugged into any compatible gas detection device. Also multiple sensors can be used on one device, resulting in a gas detector that can go from measuring Phosgene to Ammonia in less than one minute.

Can I tailor a MetriNet solution to suit an application?

Yes, all MetriNet smart water quality solutions are modular. This allows for bespoke units to be built with the flexibility to add further parameters at a later stage.

How many water quality parameters will ATi’s MetriNet monitor?

The ATi MetriNet smart water quality solution can monitor 8 different parameters at once from a total selection of 16.
