CGOLDENWALL NDJ-5S Digital Rotational Viscosity Meter Viscometer Rotary visometer 110V/220V 1~100,000mPa.s Accuracy:+-3.0% Reliable Quality

I bought this for our testing lab because the cheapest option through our regular supplier cost more than 5 times as much. The instructions are a little difficult to understand because they've been translated from another language but operation of the machine is quick and easy.

We've purchased the item, it came with a defect in one of the rotors, but we made the switch with amazon, and the new product was ok. The seller is really quick to answer any doubt or questions. The product itself is good in quality in relation to the price.Overall I recommend both the product and seller.

todas las mediciones me dan igual, muy inexacto, faltan mas tutoriales de cuando cambiar de rotor y velocidades
