HIGH PERFORMANCE READOUT UNIT-CUM-DATA LOGGER
The unit is a low-cost, high-performance sensor readout unit with integrated datalogger.
The sensor sensitivity can be programmed into the unit such that the readout will show calibrated engineering units, rather than millivolts or microvolts.
Use of the datalogger functions and programming the sensor sensitivity, requires a USB interface which is used to connect the unit to a PC.
