Power and Energy Meter with Interface (230 V, 50/60 Hz)

For measuring electrical active, apparent and reactive power as well as electrical work in the case of voltages and currents with any continuous curve shape. The voltage, current, frequency, phase angle phi, cos phi, cosphi and time are measured simultaneously and can be displayed digitally via a pushbutton. It is also possible to simultaneously measure and display two temperatures as well as the difference between them. This device is particularly suitable for experiments involving heat pumps and Stirling engines.
The power and energy meter can be used alone or together with a PC. It has an internal data logger with a real-time clock. All 13 parameters and the time – a total of 3100 measured values - can be stored. The storage of measured values can be commenced manually, or at a specified point in time, or if a power or temperature limit is exceeded or fallen short of. The stored data can be transferred subsequently to a PC via a RS232 interface.
Includes a Windows program and interface cable. The software permits programming of the data logger, graphic displays of measured values and export of all measured data to a spreadsheet program.
