1. Overview of the PressureChecker

The PressureChecker™ is a calibrated device that can be used to verify proper
functioning and accuracy of PendoTECH Single Use Pressure Sensors and monitors
non-invasively. It can be used to test the sensors in-situ without the requirement to
access the fluid path. In its small, hand-held enclosure are all the devices necessary to
perform the required function. PendoTECH Pressure Sensors are 100% tested at
several points in the manufacturing process, however, this device gives the ability to
verify the performance of the sensor by the end-user. PendoTECH Pressure Sensors
are also frequently used on single use bioreactors to measure pressure in the bag. The
required resolution is often less than 1 psi and the PressureChecker has the readability
and ability to regulate pressure in this range. It also has an internal pressure sensor
simulator and can be used to verify proper functioning of monitors such as the
PressureMAT™, PendoTECH Process Control Systems, or 3rd party monitors.

There are numerous applications in biopharmaceutical production processes where the
device can be used.

System Components Supplied:

 PDKT-650-950 PressureChecker pressure sensor and monitor verification tool

(with 9V alkaline battery)

 PDKT-650-905 4 foot connecting tube with luer slip
 Calibration Certificate

1.1. Key Features

The PressureChecker incorporates a specially designed pressure cylinder and precision solid-state
transducer for generating and measuring static pressure from -7 to +10.5 psi. The adjustment knob is used
to regulate the pressure, and the pressure value is shown on the liquid crystal display. A built-in
pneumatic port provides the external connection for fittings to connect to the sensor test port.

 Verify proper functioning of sensor and monitors
 Verify proper function of sensor in-situ by accessing the atmospheric reference side of sensor
 NIST Traceable
 Can be returned for annual calibration
 Battery operated for portability
