For many toxic gases, ATI offers a unique sensor response testing system unmatched by any competitive transmitter. Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to insure system integrity. Sensor response is verified with an actual gas sample, generated on demand. Generators store run time information accessible to operators, and are automatically tested for compatibility with the installed sensor.
