The SKC chek-mate Flowmeter is our easy to use differential pressure flowmeter for calibrating air flow sample pumps at flow ranges between 0.75 and 5.0 L/min. The chek-mate meets the accuracy requirements of MDHS 14/4, and other HSE air sampling methods.

  • No moving parts
  • Built-in temperature and atmospheric pressure compensation
  • Short stabilisation time
  • Accuracy to 1% over the whole measuring range
  • Auto-shutoff to conserve battery
  • Compact, portable and lightweight
  • Can be used in any orientation
  • Easy to use:
    - 1. Connect sample train to the chek-mate 
    - 2. Press the only button to turn the chek-mate on
    - 3. Wait for flow reading to stabilise to within 1-2 ml/min
    - 4. Adjust pump flow if necessary
    - 5. Turn off chek-mate
