TOKISANGYO – Viscometer (TV-25 & TV-35)
Brand: TOKI SANGYO - Japan
Model: TV-25 & TV-35
 
Features: 
* Small amount sample size, which able to save cost of high value (expensive) of those particular sample.


Model TV-25 Viscometer:
There are 2 types of TV25 features a multirange function, B type (spindle type) and E type (Cone-plate type) that only needs a small amount of 1ml.
 
Model TV-35 Viscometer:
TV35 features a program and multi-range function, meets various fluid, measurement requirements and measures a viscosity efficiently. Setting a rotational speed per 0.1rpm expands measurement range.

 
Common Features of TV-25 / TV-35: 

• Rotational speed: Users can set a rotational speed from 0.1 rpm to 100.0 rpm per 0.1 rpm.
• Auto zero-User span: This function lets users calibrate viscometer and correct unit-to-unit variables easily.
• Measurement conditions memorized function: This function can memorize 5 patterns of measurement conditions in manual, auto-stop Time Visco, program model each.
• Autostop Function: Measurement is automatically terminated at a prescribed time or when the liquid measured attains a preset viscosity.
• Remote control function: To start and stop the main unit can be operated by outer signal dry contact. And using the output signal open collector, the situation of viscometer can be confirmed by buzzer and lamp.
• Upper and lower limit warning: This function informs users with buzzer as a viscosity exceeds an upper or lower viscosity prescribed beforehand.
• Preheat function: Viscosity measurement can be automatically started at a pre-selected time to allow for a preheat “Waiting” period.
• Data interchangeability: Data is cross-compatible with that of conventional viscometers conforms JIS and ISO standards.
