Optic System & Thermistor Tester
Model 1391
The Model 1391 Optic Tester is a versatile unit that is
capable of testing many products found on truck overfill systems. Its ease
of use, portability and flexibility provide the user with not only confidence
that his system will function at the load terminal, but the 1391 also aids
the user during troubleshooting conditions. The 1391 simulates terminal rack
signal levels in order to test the truck’s overfill protection system.
