It has the advanced optical system based on a special tungsten lamp and a narrow band interference filter that allows most accurate and repeatable readings. All instruments are factory calibrated and the electronic and optical design minimizes the need of frequent calibration. With the powerful CAL CHECKTM validation function you are able to validate good performance of your instrument at any time. The validation procedure is extremely user friendly. Just use the exclusive Hanna ready-made, Nist traceable standards to verify the performance of the instrument and recalibrate if necessary. All instruments are splash proof and the lamp and filter units are protected from dust or dirt by a transparent cup. This makes the instruments fulfill field applications. Display codes aid the user in routine operation. The meter has an auto-shut off feature that will turn off the instrument after 10 minutes of non use or after 1 hour if left in the calibration mode. The meter uses an exclusive positive-locking system to ensure that the cuvet is in the same position every time it is placed into the measurement cell. It is designed to fit a cuvet with a larger neck making it easier to add both sample and reagents. The cuvet is made from special optical glass to obtain best results. The HI 95771 is a dual range meter that can measure the chlorine (Cl 2) content in water samples in the 0 to 5.00 mg/L (ppm) range and in the 0 to 500 mg/L (ppm) range. The methods are an adaptation of Standard Methods for the Examination of Water and Wastewater, 20 th edition, 4500-Cl. The reagents are in powder form and are supplied in packets. The amount of reagent is precisely dosed to ensure the maximum repeatability. FACTORY CALIBRATION RESET It is possible to restore factory calibration: · Enter the calibration mode by holding CAL CHECK for three seconds. · Hold ZERO/SET for 10 seconds. The display will show for 2 seconds "F.CAL" and "771" or "701" appears. The factory calibration is automatically restored and the instrument is ready for measurement by displaying "771" or "701" on the LCD depending to which parameter code has been selected. or BATTERY REPLACEMENT Battery replacement must only take place in a non-hazardous area. Simply slide off the battery cover on the back of the meter. Detach the battery from the terminals and attach a fresh 9V battery while paying attention to the correct polarity. Insert the battery and replace the cover. 9V SLIDE OFF ACCESSORIES REAGENT SETS HI 95771-01 Reagents for 100 Chlorine Ultra High Range tests HI 95771-03 Reagents for 300 Chlorine Ultra High Range tests HI 93701-01 Reagents for 100 Free Chlorine tests HI 93701-03 Reagents for 300 Free Chlorine tests OTHER ACCESSORIES HI 95771-11 CAL CHECKTM Standard Cuvets (1 set) HI 710009 Blue rubber boot HI 710010 Orange rubber boot HI 721310 9V battery (10 pcs) HI 731318 Tissue for wiping cuvets (4 pcs) HI 731331 Glass cuvets (4 pcs) HI 731335 Caps for cuvets (4 pcs) HI 93703-50 Cuvets cleaning solution (230 mL) 21 ABBREVIATIONS °C: °F: LCD: mg/L: mL: degree Celsius degree Fahrenheit Liquid Crystal Display milligrams per liter. mg/L is equivalent to ppm (part per million) milliliter 4 · Press READ/TIMER and "SIP" will blink during measurement. · The instrument will show for three seconds the CAL CHECKTM standard value, i.e. 100 for "771" chlorine ULTRA HIGH RANGE or 1.00 for "701" chlorine LOW RANGE. Then the date of last calibration (e.g.: "01.08") appears on the display, or "01.01" if the factory calibration was selected. In both cases the number of the month is blinking, ready for date input. Note: if the display shows "ERR" the calibration procedure failed. Verify that both CAL CHECKTM Standards HI 95771-11 Cuvets, A and B, are free from fingerprints or dirt and that they are inserted correctly. DATE INPUT · Keep READ/TIMER pressed to scroll to the desired month number (01-12). · When the correct month has been set, press ZERO/SET to confirm. Now the display will show the day number blinking. Keep READ/ TIMER pressed to scroll to the desired day number (01-31). Note: it is possible to change from day to month and vice versa by pressing ZERO/SET. · When both the day and month have been selected, hold CAL CHECK for three seconds to store date and calibration values. The instrument will show for one second "Stor", to confirm that the new calibration data has been accepted. · The instrument will return automatically to the measurement mode by displaying "771" or "701" on the LCD depending to which parameter code has been selected. 20 SPECIFICATIONS for 771 Chlorine ULTRA HIGH RANGE Range 0 to 500 mg/L Resolution 1 mg/L from 0 to 200 mg/L; 10 mg/L above 200 mg/L Precision ±2 mg/L @ 100 mg/L Typical EMC Deviation ±1 mg/L for 701 Chlorine LOW RANGE Range 0.00 to 5.00 mg/L Resolution 0.01 mg/L from 0.00 to 3.50 mg/L; 0.10 mg/L above 3.50 mg/L Precision ±0.02 mg/L @ 1.00 mg/L Typical EMC Deviation ±0.01 mg/L or or Light Source Light Detector Method Environment Battery Type Auto-Shut off Dimensions Weight REQUIRED REAGENTS Code HI 95771A-0 HI 95771B-0 HI 93701-0 Tungsten lamp with narrow band interference filter @ 525 nm Silicon Photocell Adaptation of Standard Methods for the Examination of Water and Wastewater, 20th edition, 4500-Cl.

Precision is usually expressed as standard deviation (SD). Accuracy is defined as the nearness of a test result to the true value. Although good precision suggests good accuracy, precise results can be inaccurate. The figure explains these definitions. In a laboratory using a standard solution of 100 mg/L chlorine and a representative lot of reagent, an operator obtained with a single instrument a standard deviation of 2 mg/L. CALIBRATION PROCEDURE Note: It is possible to interrupt calibration procedure at any time by pressing ON/OFF. Warning: do not validate or calibrate the instrument with standard solutions other than the Hanna CAL CHECKTM Standards, otherwise erroneous results will be obtained. For accurate Validation and Calibration results, please perform test at room temperature: 18 to 25°C (64.5 to 77.0°F). CALIBRATION PROCEDURE · Select the parameter code "771" for chlorine ULTRA HIGH RANGE or "701" for chlorine LOW RANGE by holding ZERO/SET (see page 13). · Enter the calibration mode by holding CAL CHECK for three seconds. · The date of the last calibration appears (e.g.: month "01", day "08"). "F.CAL" means that the factory calibration is selected. Note: at this point it is possible to reset the ...
