Digital Indicator

Digital Indicator .
Digital Indicator for Science Lab Equipment Laboratory Instruments Manufacturers, Engineering Lab Equipments Manufacturers
The digital indicator may be battery powered or mains powered using the standard power adaptor supplied. The power adaptor is intended for worldwide use and has four interchangeable plugs to suit all regions. The unit can operate on 110 volts or 230 volts at 50Hz or 60Hz.
When connected to an appropriate probe, the unit will indicate frequency of the pulses from the propeller that can be converted to water velocity using the calibration chart supplied with the probe. The unit can be programmed to read water velocity directly in units of cm/s by entering a calibration constant for the probe in use. Alternatively the unit can be programmed to count the pulses continuously, allowing averaging of the velocity measurement over a longer period.
