The PCMT 8000 uses less harnesses to test the same amount of monitor types as previous tester models, has integrated Port1/SDLC testing capability, now has Flashing Yellow Arrow Tests and retains the ease-of-use of the Windows setup and operating software that has been enhanced to be even more user-friendly!
Where do you keep your big box of suspect BIUs; under your desk or tucked nicely out of sight on that dusty old shelf? No longer do traffic signal techs have to play the "BIU Swap Game"! Quickly and reliably check any BIU with the BIUT-820 which provides comprehensive, fully automated testing in the field or at the shop.
The MST-700 is an easy to use, fully automated tool designed to verify the proper operation of Load switches, Flashers, and Transfer Relays that are used in traffic signal installations conforming with NEMA or CalTrans specifications.
