Chek-mate
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
