Ralston FieldLab 

The first laboratory grade pressure meter calibrator made to work like you do - no matter where you do it.  

Speed through Calibration Tests

Log digital readings for both the FieldLab (reference) and DUT (device under test) with immediate tolerance feedback at each test point. When the test is complete, download the results to your laptop and export them as a PDF or CSV file. 

Available with a wireless option that allows you to run tests from the cab of your truck or mobile office trailer and save them directly to your laptop with the included software.

Snapshot Logging 

Record multiple single data points and save them in one data set, along with the time, date, and any custom info you wish to add. Capture clear, precise readings with traceable results.

Name test points (or use an unlimited number of unnamed points), set target pressure and tolerances for every point, and save test modes so you can easily repeat tests whenever needed.

Precision PSV Testing

Pressure safety valve crack tests and seat tightness tests can be performed with precision while generating solid data to back up your observations.

Follow standard ASME Section 8 or create your own tests to follow your SOPs.

Work in Hazardous Locations No Matter How You Say It.

What good is rugged mobility if you can't take your tools to where the job is? The FieldLab is certified Intrinsically Safe for hazardous locations anywhere in the world.

Continuous Pressure Data Logging

For general-purpose data logging, the FieldLab continuously logs pressure at customizable intervals, supporting up to three months of monitoring on a single charge.

With onboard storage for up to 3.9 million data points, it replaces traditional chart recorders with a completely digital system for storing and downloading pressure logs.

Change Engineering Units With One Touch of a Button

The FieldLab comes with every standard engineering unit used to measure pressure or vacuum. Swap units instantly without searching through menus.

Customize the FieldLab Digital Pressure Calibrator to only show the Units you use most with the FieldLab Digital Pressure Calibrator Software.

Learn New Tricks with Test Modes

Create custom tests based on job requirements and the format you need for your results.

Activate a saved Test Mode to ensure repeatability and traceability every time the test is performed, then share it with colleagues to reduce setup time and streamline your workflow.

Work in the real world

Below freezing or above blazing - the FieldLab Digital Pressure Calibrator is designed for where you work. Spend less time onsite and get more tests done in an 8 hour day without tedious processes or pen and paper.
