Product Description

Lab Testing Rotational Viscometer
Model:NDJ-79/7

 

Product Description

The instrument is suitable to be used for relevant laboratories and factories to determine absolute viscosity of Newton liquids and apparent viscosity of non-Newton viscosities. It can be used to determine viscosity of petroleum, resins, paints, inks, sizing agents, cosmetics, creams, pharmaceuticals, and asphalts. For liquids of different viscosities, and different measurement requirements, you can select different combinations for determination. It is small, light, convenient to be operated, easy to be maintained, durable and it can determine viscosity of liquids rapidly and reliably.

I. Main technical characteristics
1. The instrument is driven by a synchronous motor. The motor rotates at a constant speed and it is not affected by changes in load and the power supply voltage.
2. It is equipped with two measurement units. Each unit contains a measurement chamber and several rotation cylinders with rotation shaft, so that it can meet different measurement requirements.
3. It adopts arc type dial, so it is convenient to read reading.

FAQ

1. How long is the delivery time?
Normally goods will be shipped out within 7-10days after contract signed and down payment received.

2. Is it possible to make our own brand/logo on your product?
Yes, but depends on MOQ.

3. What's your MOQ?
This depends on different types of products. If it is a large machine, the MOQ is usually 1 set. For small instruments, such as thermometers, the MOQ is 50 pieces.

4. What kind of payment term you accept?
Normally,
1) If total contract value less than USD 10,000.00 : 100% T/T in advance after contract signed.
2) If total contract value more than USD 10000.00 : 50% T/T in advance after contract signed and 50% T/T after receipt of BL copy. Or, irrevocable LC is acceptable.
