Altek 2500T User manual
PneuCal III
The 2500T offers
simplistic set-up to
make your job
easier.
The Altek PneuCal III is a highly accurate, digital calibrator for pneumatic field
instrumentation, including valve actuators, P/I transmitters, controllers, gauges,
switches and recorders. It is especially suitable for checking 3 to 15 PSI
systems. Its dual precision regulators enable output of set and variable
pressures to control devices, while the switching manifold allows fast selection
among the pressure ports. The unit simultaneously displays pressure and mA,
and has a built-in loop power supply. Accuracy is ± 0.035% of full scale for
all ranges. Optional external sensors measure other pressure ranges.
Each Unit Includes: Built-In Switch Testing, AC Adapter/Charger, Test Leads,
Hard Shell Carrying Case, Instructions, Built-in Pressure and Vacuum Pumps.
