CIH Equipment will get your air sampler in top condition. We want to make sure that your air sampler, before it leaves our laboratory, can operate at the correct flow rates, the pneumatic system is clean, the motor is trustworthy, the battery lasts, and the fault sensors are in proper operating mode. Our air sampler laboratory is set up to determine flow range, static head pressure versus flow, and well-functioning fault sensors. Pneumatic systems are evaluated for function, wearable parts and NIST Traceable flow and pressure standards.
