3. GENERAL DESCRIPTION HI987134 is an ISO 7027 compliant portable turbidimeter, designed for water-quality measurements, that provides reliable and accurate readings on low-turbidity values. Depending on required accuracy, the user can select between normal, continuous or signal averaging measurement modes. It has an advanced optical system that uses a Light Emitting Diode (LED) and two detectors that allows for accurate and repeatable readings.
5. TAG IDENTIFICATION SYSTEM Hanna Instruments is the first manufacturer of turbidity instruments that added the unique Tag Identification System (T.I.S.) to its portable meters. T.I.S. meets the more restrictive needs of users, combining all advantages of this system with measurements and data management.
6. PRINCIPLE OF OPERATION Water turbidity is an optical property that causes light to be scattered and absorbed, not transmitted. The scattered light passing through a liquid is primarily caused by suspended solids. The higher the turbidity, the greater the amount of scattered light. The light beam that passes through the sample is scattered in all directions by the particles.
8. FUNCTIONAL DESCRIPTION 8.1. INSTRUMENT LID CLOSED LID OPENED BATTERY COVER REMOVED 1. Cuvette lid Lid must be closed during measurement. 2. Cuvette holder Cuvette mark and holder mark must be aligned when inserting the cuvette into the holder. 3. Liquid Crystal Display (LCD) 4.
8.2. CONNECTORS 1. AC adapter connector, used to connect an external AC adapter. 2. RS232 connector, used to transfer data through the RS232 connection using HI920011 serial cable to connect to the PC. 3. Tag reader connector, used to read the location identification number during logging by touching the tag with the connector.
8.4. KEYPAD 1. CAL key, press to enter or exit calibration. When in Setup, used to start or stop editing a parameter. 2. ON/OFF key, press to turn the instrument ON/OFF. 3. GLP key, press to enter or exit GLP feature. When in Setup, used to increase the set values.
9. GENERAL TIPS FOR ACCURATE MEASUREMENTS 9.1. CUVETTE PREPARATION The cuvette is part of the optical system as the light reaches the sample by passing through the cuvette glass. Measurements are affected by dirt, dust, scratches, or fingerprints present on the cuvette surface, and so special care must be taken during sample preparation.

Warning: Do not apply the oil in excess, it may retain dirt or contaminate the cuvette holder of the instrument and alter the turbidity readings. To correctly oil a cuvette: 1. Apply a few drops of oil. 2. Wipe the cuvette thoroughly with a lint-free cloth. 3.
Page 15
6. Use a water-resistant pencil to mark this position on the thicker white band on top of the cuvette. Always use this position to align the cuvette with the mark on top of the instrument. Multiple Matching For correct multiple matching: 1.
9.2. SAMPLING TECHNIQUE For consistent results, when selecting a representative sample: • Gently mix the water before taking the sample. • If the sample is taken from a pipe, discard the first few liters. • If measuring a non-uniform source, collect samples from different places and mix them. When measuring a collected sample: •...
Page 17
Warning: Changing the surface tension will cause a rapid settling of particles that cause turbidity. Sample should be analyzed as soon as possible. Surfactant contribution to the turbidity readings is negligible. Ultrasonic Bath Ultrasonic waves, though efficient in removing air bubbles, should be used with care as can alter sample turbidity characteristics, by modifying the shape and size of particles which cause turbidity.
10. MEASUREMENT PROCEDURE General Guidelines • Use cuvettes without scratches or cracks. • Cap the cuvettes to avoid sample spillage. • Close the lid during measurement. • Keep the lid closed when not in use to prevent dust or dirt from entering. •...

Normal Measurement Used for stable samples when normal accuracy is required, normal measurement takes about 10 seconds. During normal measurement AVG tag is not displayed and the LED is on for a minimum of 7 seconds. 1. Press READ to start the measurement. The display will show blinking dashes and the icons for cuvette, detectors and LED will appear during measurement.

3. The final averaged result is displayed in FNU. Range & Units HI987134 automatically selects the correct range for highest accuracy. If the measured value is higher than 1000 FNU (over range), the maximum value is displayed blinking.
11. CALIBRATION HI987134’s calibration procedure compensates for LED aging or changing. Supplied calibration solutions or user-own standards can both be used. The instrument is supplied with 4 AMCO standards: <0.1 FNU, 15 FNU, 100 FNU and 750 FNU, specially designed for this instrument. The turbidity standards have a shelf life and should not be used passed expiration date.
11.2. CALIBRATION PROCEDURE For best results follow correct measurement techniques. When calibrating using formazin standards, gently mix the cuvettes for 1 minute and allow the standard to settle for another minute before calibrating. Calibration can be performed in two-, three-, four-points. To stop calibration, press CAL or ON/OFF key.

At the end of the measurement, the third calibration point (100 FNU) is displayed on the first LCD line, “CAL P.3” on the second LCD line with READ tag blinking. <0.1 9. Press CAL to exit calibration or continue to Three-Point Calibration procedure. The instrument memorizes the two-point calibration data and returns to measurement mode.
At the end of the measurement, the four-point calibration is memorized and the instrument automatically returns to measurement mode. 11.3. OUT CAL RANGE FUNCTION Recommended calibration range for correct measurements is up to 40 FNU for two-point calibration and up to 150% of the third point value for three-point calibration. LCD displays a blinking CAL tag each time measurements are taken outside the calibration range.
12. LOGGING Each measurement’s information (date, time and tag ID) is stored for further analysis. 12.1. LOGGING A MEASUREMENT The log function is available after a valid measurement. 1. Press LOG/CFM when the measured value is displayed. The instrument asks for READ TAG to identify the sampling location. The location for the new record is also displayed on second LCD line.
