Redwood Viscometer Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-TM-11610
Lab Instruments Manufacturers manufactures the Redwood Viscometer Apparatus in-house at our own India facility, supplying it to petroleum-testing and thermodynamics labs, and as an OEM/private-label item to distributors and exporters across India and internationally.
What This Apparatus Does
This viscometer measures the viscosity of petroleum products by timing how long a fixed volume of oil takes to flow through a precision jet under standardised conditions. The unit comprises a hammertone-finish copper or stainless-steel water bath, a silver-plated oil cup fitted with a calibrated jet, and an electrical or gas-based heating arrangement to bring the sample to the required test temperature. The apparatus is built around the Redwood viscosity-testing method referenced in petroleum-industry test procedures such as IP 70.
Key details
| Water bath | hammertone-finish copper or stainless-steel water bath |
| Oil cup | silver-plated oil cup fitted with a calibrated jet |
| Heating | electrical or gas-based heating arrangement |
| Test method reference | IP 70 |
Typical Lab Use
Petroleum-testing laboratories and refineries use this apparatus to determine the flow viscosity of lubricating oils and other petroleum products, and engineering colleges use it to teach viscosity-measurement principles alongside our Saybolt Viscometer Apparatus, which measures viscosity by the same timed-flow principle using a different standardised jet and cup design.
Manufactured In-House
This apparatus is fabricated and assembled at our own India production facility, with the water bath, oil cup, and jet machined and calibrated in-house. Manufacturing in-house means our team controls build quality and jet-calibration accuracy at every stage, and can configure the heating arrangement or accompanying courseware for a specific curriculum or export order without waiting on an outside supplier.
Frequently Asked Questions
What does a Redwood Viscometer Apparatus measure?
The viscosity of petroleum products, by timing the flow of a fixed oil volume through a calibrated jet at a set temperature.
Is this the same as a Saybolt Viscometer?
Both measure viscosity by a timed-flow method, but they use different standardised cup and jet designs. See our Saybolt Viscometer Apparatus for the alternative method.
Can this be supplied as an OEM/private-label order?
Yes, it can be produced and packed under a buyer's own brand name and item codes for distributors and exporters ordering in bulk.
