Multi-function Process Calibrator Et2725

Multi-Function Process Calibrator ET2725 is a multifunctional, high-precision portable instrument. Specially designed for process control, is suitable for the industrial field debugging, can meet the requirements of a wide range of tasks, support source volts, current, resistance temperature detectors (RTD), thermocouples (TC), frequency, and ohms. measure and source all process parameters, such as measurement and Output can also be calibrated to secondary instruments that can measure these parameters with accuracy of 0.02%.

Product features:

Super-strong protection:The waterproof grade is IP67. Automatic protection against the signal terminals connect to the 220V
A split-screen display. The upper display allows you to measure volts, current (with loop power), resistance and continuity test. The lower display allows you to measure and source volts, current, resistance temperature detectors (RTD), thermocouples (TC), frequency, and ohms.
The accuracy 0.02% or 0.05%.
Calibrates a transmitter using the split-screen.
The measure of thermocouple provides automatic reference junction.
Automatic and manual cold end temperature compensation for TC.
Manual stepping and automatic stepping and ramping.
APSL intelligent pressure module with high precision can be selected according to customer needs to realize pressure measurement function.
