The Stormer Viscometer STM-IV is suitable for measuring paint and paint related viscosity values. Press the handle to start measuring automatically, can test Krebs unit and gram unit. The test result can be locked during the test; the built-in overload protection program will automatically stop when the range is exceeded. Equipped with a printing interface, the measurement results can be output to the computer.

1. Easy to use, no need for weights, which simplifies the testing procedure.
2. The LED display can display Krebs units and Grams units.
3. Use the HOLD key to lock the test result.
4. Compared with the old Stormer viscometer, the measurement accuracy and reproducibility are higher.
5. Built-in overload protection program, over-range automatic shutdown.
6. Equipped with a printing interface, which can output the measurement results to the computer.
