Application:
The instrument is designed and made as per the requirements about penetrometer and its accessories stipulated in the National Standard GB/T 4985 "Test Methods for Needle Penetration of Wax".
V The needle penetration of wax is expressed as the depth that a standard needle of 100 g vertically penetrates into a wax sample without any measurable friction in 5 s at 25C.
V The test temperature for wax penetration is 25 C in general.
V Each wax penetration is 0.1 mm. It is directly shown on display.
Technical parameters:
V Timing selection: 5, 8, 10, 12, 30 or 60 s;
V Timing error: Less than ± 0.1 s;
V Penetration accuracy: ± 0.1 penetration;
V Maximum penetration: 600 penetrations;
V Standard needle: 2.5± 0.05 g;
V Constant temperature bath: Made of harden glass;
V Mold: 25× 32× 3mm, a brass cylinder;
V Brass board: 65× 40× 6.5mm;
Heating power: 220 W;
