These instruments are in compliance with directives. TABLE OF CONTENTS PRELIMINARY EXAMINATION . . . . . . . . . . . [. . . ] · Fill the cuvet with 10 mL of unreacted sample, up to the mark, and replace the cap. · Place the cuvet into the holder and ensure that the notch on the cap is positioned securely into the groove. · Press ZERO and "SIP" will blink on the display. 10 mL Alkalinity 22 · Wait for a few seconds and the display will show "-0. 0-". · Add carefully the content of one packet of HI 93755-0 Alkalinity Indicator Reagent. Note: Pay attention not to spill reagent otherwise full color development may be inhibithed. · Replace the cuvet into the holder and ensure that the notch on the cap is positioned securely into the groove. · Press TIMER and the display will show the countdown prior to measurement. In both cases "SIP" will blink during measurement. · The instrument directly displays the alkalinity in mg/L of CaCO3 on the Liquid Crystal Display. 23 Alkalinity BROMINE SPECIFICATIONS Range Resolution Precision Typical EMC Deviation Light Source Method 0. 00 to 10. 00 mg/L 0. 01 mg/L ±0. 05 mg/L @ 2. 00 mg/L ±0. 01 mg/L Tungsten lamp with narrow band interference filter @ 525 nm Adaptation of the Standard Methods for the Examination of Water and Wastewater, 20th edition, DPD method. The reaction between bromine and the reagent causes a pink tint in the sample.

MEASUREMENT PROCEDURE · Select the program number corresponding to Bromine on the secondary LCD by pressing PROGRAM and . · Fill the cuvet with 10 mL of unreacted sample, up to the mark, and replace the cap. · Place the cuvet into the holder and ensure that the notch on the cap is positioned securely into the groove. · Press ZERO and "SIP" will blink on the display. 10 mL Bromine 24 · Wait for a few seconds and the display will show "-0. 0-". Replace the cap and shake gently for about 20 seconds to dissolve most of the reagent. · Replace the cuvet into the holder and ensure that the notch on the cap is positioned securely into the groove. · Press TIMER and the display will show the countdown prior to measurement. Alternatively, wait for 2 minutes and 30 seconds and press READ DIRECT. In both cases "SIP" will blink during measurement. · The instrument directly displays concentration in mg/L of bromine on the Liquid Crystal Display. INTERFERENCES Interference may be caused by: Chlorine, Chlorine Dioxide, Ozone. In case of water with hardness greater than 500 mg/L CaCO3, shake the sample for approximately 2 minutes after adding the reagent. In case of water with alkalinity greater than 250 mg/L CaCO3, the color of the sample may develop only partially, or may rapidly fade. To resolve this, neutralize the sample with diluted HCl. 25 Bromine CALCIUM HARDNESS SPECIFICATIONS Range Resolution Precision Typical EMC Deviation Light Source Method 0 to 500 mg/L (as CaCO3) 5 mg/L ±10 mg/L @ 200 mg/L ±5 mg/L Tungsten lamp with narrow band interference filter @ 525 nm Colorimetric Method. The reaction between calcium and the reagents causes a violet to orange tint in the sample. [. . . ] Use HI 920010 cable to connect the meter to the PC, start the terminal program and set the communication options as follows: 8, N, 1, no flow control. Command Types To send a command to the meter the scheme is: <DLE> <command> <CR> This line makes the computer send a Data Link Escape character (/ or ?), the command expressed as a number or a 3-character sequence and a CR character. Note: Windows Terminal® and all the other terminal programs that support the ANSI escape sequence, represent the DLE character by the string `^P' and the CR character by the string `^M'.
