Warnings

  • Read this manual carefully before using: this manual should be read by anyone who will be operating the F-900.
  • By following the guidelines, the F-900 will function according to the specifications in this instruction manual.
  • All repairs should be performed by a Felix Instruments technician.
  • The analyzer must be used to measure the rate of ethylene in the presence of nitrogen, oxygen and carbon dioxide. All other gases in high concentration could lead to erroneous measurements, or the destruction of the sensor. Do not use the instrument in the presence high concentrations of aromatic solvents, hydrocarbons or other volatile organic compounds, such as in unventilated painting rooms or chemical storage rooms.
  • Damage to the analyzer can occur if the fluid reservoir level is too low or if the inlet and outlet gas connections are blocked while the pump operates. This can cause false readings or irreparable damage to the sensor.
  • If smoke comes out of the analyzer, turn off the power immediately and contact Felix Instruments-Applied Food Science.
  • Keep the analyzer in a clean and ventilated room at ambient temperature.
  • Do not allow fluid to aspirate in the analyzer, which can destroy the sensors.
  • Do not use the F-900 in a high RF (radio frequency) environment. High RF will disrupt the F-900.
  • ESD (electrostatic discharge) interferes with the F-900 measurement data.
  • Do not tilt the F-900 when Chamber IN contains water!
  • Do not store the F-900 without charged batteries! The internal batteries must have charge to maintain the accuracy of the sensors, even when the unit is powered off. It is recommended to keep the instrument connected to the power supply for long term storage.


Warning

The analyzer has a reservoir containing 1 mol of sulfuric acid (2N H₂SO₄). Avoid contact with skin and eyes. If contact occurs, rinse thoroughly with water or use an eyewash or safety shower. Do not drink the contents of the fluid reservoirs as it could cause chemical burns. See Appendix I for the safety data sheet and further information on sulfuric acid.
