Intelligent imported Catalytic Combustion or Electrochemical sensor; Audible-Visual-Vibrating alarm; Large LCD real-time display; simple operation; Quick and accurate response to the konwn gas. Also called (Combustible/Flammable/Explosive) (Toxic/Poisonous) (Oxygen) gas detector.

KT-603 Combustible/Toxic/Oxygen Gas Detector responds quickly and accurately to COMBUSTIBLE/TOXIC/OXYGEN GASES and emits audible-visual-vibrating alarms in time if gas leakage or danger occurred(Oxygen concentration is too high or too low). This instrument works well in a harsh operating environment which is broiling, cold, damp, dusty, etc. Detection and alarm will continue even if the detector is dropped or crashed.

Features
1. Small in size and light in weight
2. Continuously LCD real-time display of gas concentration and composition
3. Audible visual vibration alarm
4. Two stage alarm threshold can be adjusted according to actual needs
5. Simple automatic calibration program
6. Fully functional self-testing: sensor, integrity of battery and circuit, acoustic & visual & vibration three-stage alarm.
