Presscision PPT portable digital test instrument
Presscision’s PPT is a portable digital test instrument for automated pressure and temperature testing of commercial and residential plumbing installations. It is used to conduct regulatory testing of natural gas installations, water supply lines, DWV lines, fire-suppression systems and medical-gas distribution systems. The instrument increases a user’s productivity through accuracy and automation and creates a permanent, tamper-proof test record. It supports multiple sensor types and ranges via rugged, external sensor “pods.” Current pods provide pressure measurement ranges of 0-15 psig and 0-150 psig at 0.25% accuracy, and a temperature measurement range of minus 67° to 302° F at 0.3% accuracy.
