    Reviews


  2. CheckPoint is a hand-held gas analyser for the testing of MAP products within different industries e.g. the pharmaceutical, and the food & beverage industry.

    The analyser is small, robust, practical and ergonomically designed. CheckPoint is able to test oxygen and carbon dioxide using a syringe needle for gas sampling.
    CheckPoint is ideal for machine and product setups.

    CheckPoint is battery operated and can be powered by rechargeable or ordinary batteries.
    The O2 version is equipped with an electrochemical sensor and the O2/CO2 version is equipped with an electrochemical and an infrared sensor.
    CheckPoint remembers up to 10 measurements.
    The large and easy readable LED based display gives you the result in a few seconds.


    Available in two versions:
    • CheckPoint O2 for oxygen only

    • CheckPoint O2/CO2 for combined measuring of oxygen & carbon dioxide



    This product is especially designed for those who need the advantages of a very portable unit, which can offer a good accuracy.
    Especially the accuracy of the CO2 sensor in hand-held devices is one of the best on the market.
    Due to new state-of-the-art technology, Dansensor can now offer a very satisfactory solution to this point.

    CheckPoint in carrier case
    The new rugged carrier case protects the CheckPoint gas analyser during transport and when not in use.
    Accessories can be stored in the carrier case as well.


    Calibrated and ready to use

    CheckPoint comes with a certificate of calibration and should be re-calibrated with six month interval. The operator never needs to worry about compensation for air pressure or flow verification because this is all taken care of automatically.

    If you wish to re-calibrate the unit, this is a very simple process. You simply use the automatic hot key calibration routine available in the menu.

    Principle of operation Sensor system Oxygen

    The CheckPoint O2 is based on an electrochemical sensor. The sensor operates like a kind of battery producing a current corresponding to the concentration of the gas passing the sensor. The value of the current is converted into a concentration value and shown in the display. The sensor is remarkably sturdy and stable, the readings are highly repeatable and the sensor is very fast. The sensor will not saturate in high oxygen concentrations, which means that the CheckPoint O2 can be used across a broad range of applications with a measuring range from 0-100% with a high resolution – still with high speed and accuracy.


    Carbon dioxide

    The CO2 sensor is a self-contained, non-dispersive IR sensor with IR source and single wavelength filter. There are no moving parts and the sensor is very sturdy. The CO2 sensor range is 0-100%. The sensor only needs calibration every 6 months and the reading is not influenced by humidity, ambient air pressure or temperature.
