The DF-HKUPG-PUF series upgrade kits are designed to upgrade existing analog PUF air sampling stations currently utilizing chart recorders and electromechanical timers. The DF-HKUPG-PUF upgrade kit eliminates the need to purchase an entirely new air sampling system.

The Installation of the DF-HKUPG-PUF upgrade kit will provide the following benefits:

(1) Automatic Normalization of flow rates and air sample volumes to an internationally recognized Reference Temperature and Pressure Standard
(2) Automatic electronic flow control
(3) Accurate elapsed time measurement
(4) RS232 communications port for integration with the F&J Data Storage Device, or F&J ruggedized cellular phone system for remote and unattended air samplers.

The typical operating flow rates can vary from the standard 30 to 300 LPM, or another more appropriate flow range to conform to the customer requirements.
