Introduction

RGR CALKIT can be used to calibrate all Aeroqual sensor heads except ammonia, perchloroethylene, ozone and dust.

Gas calibration using the RGR CALKIT should always be completed in a location with adequate ventilation.

  1. The calibration accessory has barbed fittings that are intended to fit with 1/8” ID tubing.
    • The calibration accessory has barbed fittings that are intended to fit with 1/8” ID tubing.

    • Care should be taken in selecting a tubing material that is appropriate for the type of gas that you will be using to calibrate the sensor head.

    • PVDF tubing is appropriate for most gases but the tubing's datasheet should be consulted for a full list.

    • Either side of the calibration accessory can be designated the inlet or the outlet.

    • Not all gas that enters through the inlet exits through the calibration accessory outlet; be advised that some gas exits through the sensor head exhaust. Depending on your calibration gas of choice and concentration levels, you may need to perform this calibration under a fume hood.

  2. Make sure the valve on your flow gas regulator is fully off.
    • Make sure the valve on your flow gas regulator is fully off.

    • Screw the gas regulator onto your gas cylinder. When the regulator is correctly fitted, the pressure indicator will show the cylinder pressure.

    • Always point the cylinder and regulator away from yourself and others when attaching or removing a pressure regulator.

    • Secure the cylinder so it can't be knocked over while the regulator is attached.

  3. Connect tubing to gas source and ventilation.
    • Connect tubing to gas source and ventilation.

    • Either side of the calibration accessory can be designated the inlet or the outlet

  4. Attach the sensor head to Ranger
    • Attach the sensor head to Ranger

    • Turn Ranger On

    • Attach the calibration accessory to the sensor head

  5. Check the cylinder pressure to ensure there's enough gas to perform the calibration (10% of full pressure should be enough).
    • Check the cylinder pressure to ensure there's enough gas to perform the calibration (10% of full pressure should be enough).

    • Gently turn the regulator valve anticlockwise and flow the target gas at >1L/min until the reading stabilizes (about 10 minutes).

  6. Wait for the gas reading to stabilize on the display of the Ranger
    • Wait for the gas reading to stabilize on the display of the Ranger
