Portable viscometers are typically small, lightweight, easily portable devices used for viscosity testing outside of the laboratory. The following is a detailed introduction to the selection points and precautions:
select points
Test range: Choose a portable viscometer suitable for the viscosity range of your test object to ensure the accuracy of the test viscosity.
Accuracy and repeatability: The accuracy and repeatability of a portable viscometer is one of the key indicators for evaluating its performance. You can understand its accuracy and repeatability by checking the product specification sheet.
Measurement method: choose the test method you need, generally there are various methods such as rotary type, vibration type and compression type.
Reliability and durability: Portable viscometers need to be used in complex environments, so it is necessary to choose products with reliability and durability.
Ease of operation: Choose products that are easy to operate and use, and recommend easy-to-understand instructions to avoid test errors.
Precautions
Viscometers require regular calibration to ensure their accuracy and reliability.
Before use, please read the instructions carefully to understand the usage methods and precautions.
Before testing, please return the viscometer to room temperature and warm it up.
Wind, vibration and other disturbances should be avoided during the test, otherwise the accuracy of the test results will be affected.
During use, avoid exposing the viscometer to corrosive substances such as chemicals, acids, alkalis, and solvents.
During use and storage, the viscometer should be placed in a dry, clean place and avoid high temperature, so as to avoid the viscometer from being affected by moisture or high temperature, which may cause inaccurate testing.
