| 1 | DISSOLVED OXYGEN ANALYSER,PORTABLE FOR USING IN BOILER WATER MEASUREMENT. IT SHOULD BE ABLE TO MEASURE DISSOLVED OXYGEN FROM 0.1 TO 200 PPB. THE RESOLUTION OF MEASUREMENT OF VARIOUS RANGES MUST BE CLEARLY INDICATED. THE MICROPROCESSOR BASED ANALYSER SHOULD CONTAIN FACILITY FOR AUTO CALIBRATION, AUTO RANGING / RANGE SWITCHING,AUTOMATIC TEMPERATURE COMPENSATION AND DIGITAL DISPLAY. THE EQUIPMENT SHOULD BE COMPLETE WITH SENSOR, FLOW CELL, SPARE MEMBRANE MODULE, CARRYING CASE/HANDLE PROTABILITY. THE EQUIPMENT SHOULD BE OPERATE D WITH RECHARGEABLE BATTERY. MEASURING RANGES:0-20 PPB,0-200 PPB, RESOLUTION: 0-200 PPB : 0.1 PPB. REPEATABILITY: <20 PPB : 0.1PPB, <200PPB : 0.3PPB. ACCURACY: +/- 1% OF THE READING CALIBRATION RANGE: AUTO CALIBRATION WITH AIR, DRIFT : 0.5% MAX OF THE READING. TEM PERATURE COMPENSATION RANGE 0 TO 45DEG.C, SENSOR RESPONSE TIME < 10 SECOND OR BETTER. SAMPLE REQUIREMENT TEMPERATURE : 0 TO 100 DEG. C, FLOW 100 TO 200 ML / MIN. PH > 4, PRESSURE : 1 BAR | DISSOLVED OXYGEN ANALYSER,PORTABLE FOR USING IN BOILER WATER MEASUREMENT. IT SHOULD BE ABLE TO MEASURE DISSOLVED OXYGEN FROM 0.1 TO 200 PPB.
