Operating a Methane Gas Detector: 

Power On/Off: 

  • To power on the GAO Tek methane gas detector, locate the power button and press it. 
  • Ensure the device undergoes the startup process and displays the appropriate indicators. 
  • To power off, press and hold the power button until the device shuts down. 

Setting Measurement Parameters: 

  • Use the menu or interface provided by GAO Tek to set the required measurement parameters such as alarm thresholds, units of measurement, and sampling intervals. 

Sampling Procedure: 

  • Ensure the gas detector is in a suitable location representative of the monitored area. 
  • Follow the guidelines in the user manual for proper sampling procedures. 
  • GAO Tek’s user manual will provide specific details on sample collection and device placement. 

Interpreting Readings: 

  • Regularly check the display for methane concentration readings. 
  • Familiarize yourself with GAO Tek’s scale and unit of measurement for accurate interpretation. 
  • Take appropriate actions if readings exceed preset thresholds. 

 

Maintaining a Methane Gas Detector: 

Cleaning and Calibration: 

  • Regularly clean the sensor according to GAO Tek’s recommendations using appropriate cleaning materials. 
  • Follow GAO Tek’s calibration procedures at specified intervals or when prompted by the device. 

Battery Maintenance: 

  • If the GAO Tek methane gas detector operates on batteries, follow the manufacturer’s guidelines for battery maintenance. 
  • Replace batteries as needed with GAO Tek’s recommended battery types. 

Sensor Replacement: 

  • If the sensor reaches the end of its lifespan, replace it with GAO Tek’s authorized replacement sensors. 
  • Ensure the replacement procedure aligns with our instructions in the user manual. 

 

Calibrating a Methane Gas Detector: 

Pre-Calibration Preparations: 

  • Before calibrating, ensure the gas detector is in an area with a known, stable concentration of methane. 
  • Use a GAO Tek calibration gas source or a certified gas cylinder for accurate calibration. 

Calibration Process: 

  • Access the calibration menu on our methane gas detector. 
  • Following GAO Tek’s instructions, introduce the calibration gas to the sensor. 
  • Adjust the readings on the device to match the known concentration of the calibration gas. 

Post-Calibration Verification: 

  • After calibration, verify the accuracy of the device by checking readings against another known gas concentration. 
  • Make any necessary adjustments using GAO Tek’s calibration procedures. 
  • By following these detailed steps and referring to our user manual, you can ensure the proper operation, maintenance, and calibration of the methane gas detector to maintain optimal performance and accuracy.Â
