LVDV-1

Touchscreen Rotational Viscometer

Measight LVDV-1 is an LV-series touchscreen rotational viscometer with a catalog speed range of 0.3–100 rpm. The listed configurations include standard spindles and separate low-viscosity or small-sample options. Timed measurements and an RS232/Bluetooth data package are described in the catalog. Confirm the working range, cup volume and included software for the exact setup rather than treating all accessories as standard.

5-inch HD IPS touchscreen
PT100 temperature probe included
Stepless speed control
Bluetooth and cloud-data app
RS-232 PC or micro-printer connection
Timer for repeatable testing of thixotropic samples

Measurement and data workflow

Timed measurements help keep the test duration consistent when comparing thixotropic samples. Level the instrument before testing and record the spindle, speed and sample temperature with each result. RS232 supports connection to compatible computer software or a micro-printer; confirm the software and accessory package with the quotation.

Accessories and configuration

A thermostatic bath, low-viscosity adapter, viscosity reference fluids and micro-printer are available as optional accessories. Select the bath and sample container for the required test temperature.

What to include in your LVDV-1 enquiry

For a LVDV-1 quotation, provide the sample, expected viscosity and unit, test temperature, required method, sample volume and reporting needs. State the destination power supply and quantity. Ask for an itemised spindle, container, temperature-equipment and software configuration, together with the available model-specific documents.

Common questions

What speed range is listed for the LVDV-1?

The catalog lists 0.3–100 rpm with stepless adjustment. Compare the speeds required by your method with the supplied revision and the usable range of each selected spindle.

Does the LVDV-1 temperature probe control the sample temperature?

A temperature probe measures temperature; it does not by itself heat or cool the sample. Confirm the probe supplied with the instrument and the separate bath, cup or conditioning equipment required by the test method.
