The probes are warranted for a period of one year. This warranty is limited to repair or replacement free of charge. [. . . ] The probe is easy to clean and requires little maintenance. You can even select your own setpoint and be alerted of an abnormal situation with a flashing LED alarm. Measurements are highly accurate and the meters can be calibrated at one point. You no longer need to worry about battery changes either: the unit runs without interruption on 12 VDC power supply.

Temperature Automatic from 5 to 50°C (41 to 122°F) Compensation with ß=2. 4% (HI983304) or ß=2% (HI983303/6/7/8/9) Calibration Manual with one trimmer Casing IP54 Power Supply External 12 VDC (included) Dimensions 86 x 94 x 33 mm (3. 4 x 3. 7 x 1. 3") Weight 150 g (5. 3 oz. ) Alarm OPERATIONAL GUIDE TAKING MEASUREMENTS · Turn the meter on by connecting the 12 VDC power adapter to the meter and to the mains. · Immerse the EC/TDS probe in the solution, making sure that metal pins are completely submerged. · The LCD will show the EC or TDS value. Any initial variation may be due to temperature compensation and the fact that the probe is adjusting itself to the new sample. Allow the reading to stabilize and the meter will start continuous monitoring. · Whenever the EC or TDS reading varies by more than the hysteresis specified for your model from the setpoint, the red alarm LED will blink. · Adjust the calibration trimmer with the supplied screwdriver until the display shows 1410µS/cm (HI 983303) or 1380ppm (HI 983306) or 5. 00mS/cm (HI 983307) or 6. 44ppt (HI 983308) or 800ppm (HI 983309). · The calibration is now complete and the instrument is ready for use. The instrument should be recalibrated at least once a month and after performing probe cleaning procedure. Note: HI 983304 does not need calibration when used in pure water applications. CE DECLARATION OF CONFORMITY PROBE MAINTENANCE To minimize clogging and provide longer life for the probe, it is recommended to clean it often or at least once a month. · Immerse the tip of the electrode in HI 7061 Cleaning Solution for one hour. · If a more thorough cleaning is required, brush the metal pins with very fine sandpaper. · After cleaning or when not in use, rinse the probe with tap water. Note: HI 983304 does not need cleaning when used in pure water applications. ACCESSORIES HI 7631/2* EC/TDS "flow thru" probe with ½"NPT thread, ATC and 2 m (6. 6') cable (HI983304) HI 7632/2* EC/TDS "flow thru" probe with ½"NPT thread, ATC and 2 m (6. 6') cable (HI983307/8) HI 7634/2* EC/TDS "flow thru" probe with ½"NPT thread, ATC and 2 m (6. 6') cable (HI983303/6/9) Recommendations for Users Before using these products, make sure that they are entirely suitable for the environment in which they are used. Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV equipment. The metal band at the end of the probe is sensitive to electrostatic discharges. [. . . ] * 1413µS/cm for HI983303; 1382ppm for HI983306; 5. 00 mS/cm for HI983307; 6. 44ppt for HI983308; 800ppm for HI983309. · Immerse the EC/TDS probe in the solution, making sure that metal pins are completely submerged. Note: in order not to affect the accuracy of measurements, it is important that probe body does not touch nor stand close to the side walls of the beaker. The tip can lay on the bottom of the beaker.
