BIOSTELLAR Kinematic Viscosity Tester with Automatic Calculation and Printing

Model NO. KVT-265H

The BIOSTELLAR KVT-265H combines controlled-temperature capillary testing with automatic viscosity calculation and result printing. Designed for Newtonian liquid petroleum products, it measures gravity-flow time through a calibrated glass capillary viscometer at a constant temperature. Its 20 L bath provides temperature control from ambient temperature to 100.0°C, with a stated accuracy of ±0.01°C.

Quantity

Features：

Calculation and printing in one workflow: Preset the viscometer coefficient to calculate viscosity and print results automatically after testing
Single- or dual-sample operation: Parameter settings support testing one sample or two samples simultaneously
Precise bath temperature control: An RTD Pt100 sensor supports control from ambient temperature to 100.0°C, with a stated accuracy of ±0.01°C
Clear timing and results: A colour LCD displays test time and results
Visible, stirred bath: The glass bath allows sample observation, while electric stirring supports uniform bath temperature
Defined timing performance: Timing range of 0.0–9999.9 s, with accuracy of ±0.05% within 60 minutes
Supplied capillary selection: Six Pinkevitch viscometer tubes are supplied, with internal diameters of 0.6, 0.8, 1.0, 1.2, 1.5 and 2.0 mm

Advantages:

Kinematic viscosity determination of Newtonian liquid petroleum products
Routine viscosity testing in petroleum laboratories
Quality-control analysis of liquid petroleum samples
Comparative testing of samples at a defined constant temperature
Laboratory research requiring timed capillary-flow measurements and printed results

Q1: What measurement principle does the KVT-265H use?

A: It determines kinematic viscosity from the time required for liquid to flow under gravity through a calibrated glass capillary viscometer at a constant temperature.

Q2: Which samples is it designed for?

A: Newtonian liquid petroleum products.

Q3: Does it calculate viscosity automatically?

A: Yes. The viscometer coefficient can be preset, allowing automatic viscosity calculation and result printing after testing.

Q4: How many samples can be tested simultaneously?

A:The supplied information specifies one sample or two simultaneous samples through parameter settings. The four-capillary configuration does not establish four simultaneous tests.
