INTERFERENCES: Sample color and turbidity interfere with the colorimetric pH measurement. Color interference may be removed bystandardizing the instrument with the original water sample. Two drops of 0.1N sodium thiosulfate per 100 mL of sample will eliminate chlorine interference. INDICATOR, RANGE, & TEST NAME: pH Indicator pH Smart2 Test Name Chlorphenol Red 5.0-6.8 74 pH CPR Phenol Red 6.6-8.4 75 pH PR Thymol Blue 8.0-9.6 76 pH TB pH 2/3 Smart2 TEST PROCEDURES 2.04
PROCEDURE 1. Use Indicator, Range, & Test Name chart to select the indicator, corresponding to anticipated pH range and to determine corresponding test name to select from colorimeter menu. 2. Press and hold ON button until colorimeter turns on. 3. Press ENTER to start. 4. Press ENTER to select TESTING MENU. 5. Select ALL TESTS (or another sequence containing the appropriate pH test name) from TESTING MENU. 6. Scroll to and select the appropriate pH test name from menu. 7. Rinse a clean tube (0290) with sample water. Fill to the 10 mL line with sample. 8. Insert tube into chamber, close lid and select SCAN BLANK. 9. Remove tube from colorimeter. Use the 0.5 mL pipet (0369) to add exactly 0.5 mL of the pH indicator for the chosen range. Cap and mix. 10. Insert tube into chamber, close lid and select SCAN SAMPLE. Record result. 11. Press OFF button to turn colorimeter off or press EXIT buttontoexittoa previous menu or make another menu selection. Smart2 TEST PROCEDURES 2.04 pH 3/3
