The AELAB NDJ-1C is a Rotational Viscometer designed according to T0625 “Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Method)” in the JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.
The instrument is suitable for determining the absolute viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids. Its standard measurement range is 100 mPa·s～2×105 mPa·s and can be extended to 4×105 mPa·s when the optional No.30 spindle is selected.
The NDJ-1C uses microcomputer technology for temperature control, data collection and data processing. Test data can be displayed in real time on the backlit LCD, printed using the integrated micro-printer, or transferred to a computer through the RS232 communication port.
The catalog lists the following items specifically as optional accessories:
The 300℃ high temperature heating furnace is an optional accessory. The standard instrument specification lists a temperature control range of 45 ℃～200 ℃.
It is suitable for determining the absolute viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids, including asphalt Brookfield rotational viscosity testing according to T0625.
No. The product model is NDJ-1C. JTJ052 is the referenced Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.
The standard measurement range is 100 mPa·s～2×105 mPa·s. With the optional No.30 spindle, the catalog states that the range can be extended to 4×105 mPa·s.
The instrument specifies No.21, 27, 28 and 29 spindles and rotation speeds of 5RPM, 10 RPM, 20 RPM and 50 RPM. The No.30 spindle is optional.
The catalog specifies ±1% (F·S). If the optional No.30 spindle is selected, the specified measurement error is ±3% (F·S).
The specified temperature control range is 45 ℃～200 ℃ with ±0.1 ℃ temperature control accuracy.
Test data can be displayed on the LCD in real time, printed using the micro-printer, or transferred to a computer through the RS232 communication port.
The catalog lists NDJ-1C Brookfield Viscometer and Computer communication software(CD), a 300℃ high temperature heating furnace, and a 30# rotator as optional accessories.
The specified ambient temperature is 5 ℃～35 ℃ and relative humidity is ≤80%. When the controlled temperature is close to ambient temperature, the catalog instructs the user to operate an air conditioner so the ambient temperature is 5 ℃ lower than the controlled temperature.
