The SKC AirChek Essential Sample Pump is the latest addition to the AirChek line of air sampling pumps. The SKC AirChek Essential is designed for those who enjoy the simple functioning principle of SKC’s Basic Pumps but don’t want data logging or the additional features found in SKC’s premium pump, the AirChek TOUCH.


The AirChek Essential has improved packaging, high durability, a better flow range, and has long operating periods of up to 40 hours at 2000 ml/min. The AirChek Essential has a durable no-slip anti-static casing, bright running and status LEDs, and an intuitive touch keypad operation, as well as the ability to correct flow for changes in temperature and atmospheric pressure.
