Extech Instruments SC600 is a versatile electronic counting scale/balance, equipped with a high-precision load cell transducer for accurate weighing and counting applications. Its large measurement capacity, high resolution display, and multiple weighing units (grams and ounces) make it suitable for various tasks. The SC600 features a tare function for determining the net weight of objects, a self-calibration utility for maintaining accuracy, and RS-232 PC interface for data transfer.



The SC600 is microprocessor controlled and uses a load cell transducer for high accuracy and

optimumperformance.TheSC600offersalargemeasurementcapacity,highresolution,andlarge

easy to read display. The slide switch on the back of the scale allows for the selection of

measurementunits(gramorounce).



A self‐calibration utility is built‐in and the calibration data is stored internally even upon power

down. The RS‐232 PC interface allows for the transfer of measurement data between the SC600

andaPC.



The SC600 includes ‘bubble’ level, adjustable rubber feetfor leveling, and heavyduty ABSplastic
