(NOTE)
1)If the discolouration exceeds the scale, replace the tube with new one and pull the handle at half stroke(to 50mr
line). And read the concentration.
2)Correct the reading value with the temperature correction table first, and convert the value into an actual
concentration by using the conversion scale shown in the instruction sheet.
