7. All joints and seals to be helium leak tested to 1×10-7 Std. c.c./sec
8. Setup and basic operation manual included
9. Liquid Nitrogen Level Controller
   The Liquid Level Controller uses two Liquid Sensors to maintain the nitrogen level in cryogenic reservoirs. The controller uses an on-board solid-state relay to operate a cryogenic solenoid valve. The will activate the relay when the lower sensor is no longer submerged in LN2. Filling continues until the upper sensor becomes submerged. The runs off 120VAC power and features an opto-isolated zero-volt switching relay.
10. Filling will begin when both sensors have become dry and continue until both sensors have become wet. As a safety feature, the controller will not initiate (or continue) a fill operation if either sensor is unplugged.
