Name：Digital display Asphalt Viscometer
Model：LZW-5
Specification
- Scope of application:
This instrument is suitable for measuring the viscosity of liquid petroleum pitch, coal pitch, emulsified pitch and other materials in the flowing state. The viscosity of bitumen is the time it takes for the bituminous material to flow out 50 ml from the specified orifice at a specified temperature, expressed in seconds.
- Main technical indicators:
① Temperature control range: room temperature -100℃
② Temperature control accuracy: ±0.5℃
③ Heating power: 500W
④ The water pump automatically circulates water
⑤ Orifice diameter: φ3mm±0.025mm φ5mm±0.025mm φ10mm±0.025mm
⑥ Sample holding tube: inner diameter 40mm, depth 105mm
⑦ Annular water tank: inner diameter 160mm, depth 100mm
⑧ Power supply voltage: 220V 50Hz
