Redwood Viscometer
Product Code : JA-ALI-1705
The Redwood Viscometer (SKU JA-ALI-1705) measures the viscosity of oils as the time in Redwood seconds for a fixed volume to flow through a jet at the test temperature. JaincoLab offers the Redwood viscometer in electrically heated No. 1 and No. 2 models, used in oil and lubricant testing laboratories and in the fluid mechanics and fuel laboratories of mechanical, chemical and petroleum engineering colleges.
Specifications
The viscometer has a heavily silver-plated brass oil cup with a precision stainless steel jet, set in a chromium-plated bath with a heating tube or heating element and a drain cock, on a stand with levelling feet; heating is electric with Dimmerstat control on a 220 V, 50 Hz, single-phase supply.

Applications of the Redwood viscometer
The Redwood viscometer is used to compare and specify the viscosity of lubricating and fuel oils at set temperatures, and in engineering colleges it is a standard practical for showing how oil viscosity falls as temperature rises.
- Viscosity of lubricating oils in Redwood seconds at the test temperature
- Viscosity-temperature studies in fluid mechanics and fuels laboratories
- Incoming and batch checks on oils in quality-control laboratories
- Choosing No. 1 or No. 2 according to how viscous the oil is
Scope of supply and ordering
The listing covers the Redwood viscometer as the No. 1 or No. 2 model, with its oil cup and jet, heated bath, stand, ball valve, spirit level and cover, thermometer clip and 50 ml receiver. Thermometers and spare No. 1 or No. 2 cups and receiving flasks are quoted separately.
Frequently asked questions
What is the difference between Redwood No. 1 and No. 2?
Redwood No. 1 is listed for oils with a viscosity of not more than 2000 seconds at the test temperature; Redwood No. 2 is for oils that exceed 2000 seconds on the No. 1.
How is the bath heated?
Both models are electrically heated with Dimmerstat control and run on a 220 V, 50 Hz, single-phase AC supply.
Which thermometers can be ordered?
Thermometers IP 8C (0 to 45 °C), IP 9C (40 to 85 °C) and IP 10C (76 to 122 °C) are listed as extras.
