STARTER 3100M Bench Meter EN-5
2 INSTALLATION
Carefully unpack the box.
2.1 Package contents
The model ST3100M-B multi-parameter bench meter (basic package) has the following items:
In addition to ST3100M-B multi-parameter bench meter content, the ST3100M-F multi-parameter
bench meter package also includes the following:
Each pH buffer powder should be dissolved in 250ml pure water or deionized water in a
volumetric flask.
The best measurement range for STCON3 4-ring (or 4-pole) conductivity electrode is 70μS/cm-
200mS/cm. In this range the measurement accuracy can reach 0.5%.
If you use STCON3 to measure pure water which conductivity value is below 70μS/cm; the
measurement will be less accurate (approximately 1% to 5%).
Do not use STCON3 to measure conductivity value less than 2μS/cm, the accuracy is not good.
We have STCON7 pure water conductivity electrode which measurement range is 0.02μS/cm-
200μS /cm, with accuracy of 0.02μS/cm.
Additional electrodes available include the followings:
4-ring conductivity electrode (70 μS/cm-200 mS/cm.)
Pure water 2-pole conductivity electrode (0.02μS/cm-200 μS /cm)
3-in-1 plastic refillable pH electrode
Stand-alone electrode holder (include
holder base, screw and arm)
1413 µS/cm standard solution
12.88 mS/cm standard solution
RS232 Interface, Scout (Mini-din to RS232
cable)
pH Buffer Powder Set (4.01, 7.00, 10.01)
ST310 3-in-1 refillable pH electrode
STCON3 4-ring conductivity electrode
