ACETONE
*Methanol is indicated with half the sensitivity and Ethyl acetate has the same sensitivity with Acetone.
(NOTE)
1) If the discolouration is over the scale, replace the tube with new one and pull the handle at half stroke(to 50mr
line). And read a figure from the scale on the tube.
2) Correct the reading value with theTEMPERATURE CORRECTION TABLE first . and convert the value into an
actual concentration by uing the conversion scale shown in the instruction sheet.
