This is a basic product and I bought it because I am familiar with its use. We used a similar cup from another manufacturer to test hydraulic fluid viscosity BUT I can't understand the instructions. when converting measured values into viscosity. FYI I'm not an engineer but I stayed at the Holiday Inn Express last night.
