Description
The ConST273 is a high precision instrument controlled by a microprocessor and powered by an internal lithium battery or an external 10V DC adapter. Not only does the ConST273 calibrate pressure transducers and pressure switches, but has the function of sourcing 24V power and can also measures electrical signals.
Advanced silicon technology delivers 0.025%F.S accuracy for ranges up to 700bar(10000psi) and 0.1%F.S accuracy for ranges up to 2500 bar(36000psi). All of the sensors used in our pressure calibrators have been strictly aged and tested before final assembly.
