ZIPLEVEL® is a high precision pressurized hydrostatic altimeter. It works much like an aircraft altimeter that measures the weight of the air above it except that ZIPLEVEL does not use the atmosphere to measure elevation. Instead, ZIPLEVEL is a pressurized system that measures the weight of a proprietary liquid sealed within its Cord relative to a Reference Cell in the hub of its reel. This makes ZIPLEVEL 10,000 times as precise as an aircraft altimeter and immune from both barometric pressure and altitude changes. Its internal pressure prevents bubbles from desorbing from its liquid when under vacuum when the Measurement Module is above the Reference Cell during storage, stepping on or kinking the Cord. ZIPLEVEL®  is the World's only bubble free hydrostatic altimeter. An additional benefit of ZIPLEVEL's sealed, pressurized system is immunity from wind or HVAC induced errors caused by pressure differences between the Reference Cell and Measurement Module.

ZIPLEVEL® will measure over a 200' (60m) circle and 40' (12m) vertically on one setup with 0.050 internal precision. Its revolutionary High Precision functions will measure over 4' (121.9cm) vertically with paper thin 0.005 (0.1mm) internal precision. ZIPLEVEL has 16 powerful built-in functions and a PC Serial port. The job site rugged ZIPLEVEL will operate from -22F (-30C) to 158F ( 70C) for up to a year of daily use on a single 9V battery. 

ZIPLEVEL® is the World's only bubble free altimeter pressurized to prevent continual error inducing bubble formation during storage, stepping on or kinking the Cord. View this Bubble Video to see the dramatic consequence of using a historic, unpressurized, clear tube altimeter.
