Automatic kinematic viscosity within minutes
Grabner Minivis 445 is an automatic, portable micro-viscometer for determination of viscosity of fuels, oils and other liquids in the laboratory or in the field, with correlation to ASTM D445
Minivap VPS/H are stand-alone units that do not require any accessories.
The unique piston based design for automatic sample introduction and volume expansion of the measuring cell makes an expensive and bulky vacuum pump unnecessary.
The patented measuring principle in combination with the latest standards ASTM D6377 (for crude oil) and ASTM D6378 (for gasoline) avoids tedious sample chilling and air saturation.
Minivap VPS is mostly used for QC purposes while VPSH offers even more features for crude oil and R+D applications, like volatility studies at elevated temperatures and at very low vapor/liquid ratios.
Petrolab also has a new penetrometer for applications including soaps, rubber, waxes, foods, cosmetics and greases The new Petrotest Instruments PNR-12 penetrometer now boasts a fully automatic surface detection system on asphalt/bitumen testing.
The PNR-12 digitally displays test conditions and measurement results with 1/100mm resolution.
Other features of the PNR-12 include a new jog-shuttle driven menu (turn and push), audible and visual alarms to indicate when test results are outside user-programmed limits, magnification lens and selectable start delay.
