ABSTRACT OF THE DISCLOSURE An electronic control for a paper stock freeness tester. Probe- sensing means generate first and second signals when a filtrate in a filtrate chamber reaches first and second levels repectively. Cycle control and lad- der control circuits automatically and cyclically perform tests to determine the freeness of paper stock in response to these signals. An electronic free- ness measurement circuit uses the signals to measure accurately the time re- quired to accumulate a predetermined volume of filtrate in the filtrate cham- ber. The freeness measurement circuit in turn, energizes a recorder to pro- vide a freeness measurement or an input control signal to an analog control network in a closed loop control system.
