The handheld WellHead Integrity Test Logger (WHITL), with KRONOS software, maximises the efficiency of testing by letting the technician know that any pressure test being conducted will be a pass or a failure. In addition, this tool removes the technician from the testing zone making this system the safest testing tool on the market.

This net-zero digital testing tool removes the need for pens, paper, printers, scanners, and mobilising various sizes of chart recorders for low pressure to high pressure testing.

On completion of a pressure test, the data is placed onto a chart and can be emailed from the well site within minutes to the well examiner/ approver.
