Function: DSHD-2801G Penetrometer is designed and developed as per the requirements about penetrometer and the accessories stipulated in the National Standard GB/T 4985 "Test Methods for Needle Penetration of Wax". 1. 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 25 °C. 2. The test temperature for wax penetration is 25 °C in general. 3. Each wax penetration is 0.1 mm.The instrument is directly shown on display. Technical parameters: 1. Timing selection: 5, 8, 10, 12, 30 or 60 s; 2. Timing error: less than ±0.1 s; 3. Penetration accuracy: ±0.1 penetration; 4. Maximum penetration: 600 penetrations; 5. Standard needle: 2.5±0.05 g; 6. Constant temperature bath: made of harden glass; 7. Mold: 25x32x3mm, a brass cylinder; 8. Brass board: 65x40x6.5mm; 9. Heating power: 220 W; More penetrometer available: DSHD-2801E Penetrometer DSHD-2801I Automatic Penetrometer DSHD-2801G Penetrometer (For paraffin wax) DSHD-2801F Low Temperature Penetrometer DSHD-2801E1 Penetrometer DSHD-2801C Penetrometer DSHD-2801A Penetrometer
