1. PERFORMANCE
1) Measuring range :5-100 ppm
Number of pump strokes 2(200ml)
2) Sampling time :3 minutes/2 pump strokes
3) Detectable limit :1 ppm
4) Shelf life :2 years
5) Operating temperature :0~40℃
6) Temperature compensation :Necessary(See "TEMPERATURE CORRECTION TABLE")
7) Reading :Graduations printed on the tube are calibrated by Ethyl cellosolve at 3 pump strokes
and Mesityl oxide is determined by using a conversion chart.
8) Colour change :Yellow→Pale blue
2. RELATIVE STANDARD DEVIATION
RSD-low:10% RSD-mid.:10% RSD-high:10%
3. CHEMICAL REACTION
Chromium oxide is reduced.
CH3COCH=C(CH3)2+Cr6++H2SO4→Cr3+
