Viscometer Nirun Model SNB-2 with data printer to record:viscosity,­ temperature, torque % and rpm.

Unit does not require external systems of thermostatically controlled temperature to measure at 20º and 25º C. Unit allows temperature and viscosity to be read at specific temperatures without need for special thermostatically cooled baths. (*)

Viscometer Model SNB-2
Direct readout of all measurement parameters on an illuminated Liquid Crystal Display.
• Data on screen:
Speed selected: r.p.m.
Spindle selected: S.P.
Viscosity reading: cP (mPa-s)
Percentage of full scale: %
Sample temperature: °C
Temperature determinated by PT100 probe
Viscosity reading: dynamic viscosity (cP or mPa-s)
The viscometer and the PT100 can be calibrated by the user.
Auto range function to determine the maximum viscosity with each spindle/speed combination.
Ultra-sensitive front keyboard that allows easy input of all parameters.
"ERROR" message in the screen with sound alarm when the viscosity of the test material exceeds the full scale of the selected combination (SP/r.p.m.)
Sound alarm if the equipment is working at under 20% of selected full scale.
The viscometer is equipped with many pre-sets speeds, from 0.1 to 100 r.p.m.
Safety protection against sudden rises in the power supply.

Calibration software is included at no additional cost that connects via RS-232 port to a PC with (included) cable.
System consists of two components: Digital Viscometer & Printer. By avoiding the need for additional thermostatization­ equipment, one avoids considerable added costs as well as unnecessarily complicating the analysis process and using more space on the lab counter.
How can this achieved? Simple: The samples should be heated or cooled slightly over or under the temperature of the assay (generally 20ºC) the printer records all values every five seconds (viscosity, temperature, torque in % and rpm) that allows one to reproduce the assay in the same conditions. Through this simple procedure, one can get the viscosity values at the precise temperature required while recording data for registry and control, thus complying with GPL norms.
The printer roll is made of standard (non-thermal) paper, similar to that used on desk calculators. (stored printouts will therefore not fade over time). They can be easily and inexpensively replaced by those available in office supply stores. The width of the calculator printer provides ample space for clear, legible data printouts.
