BAOSHISHAN Zahn Cup - Unlock More Unknown Liquid Viscosity
This is a Zahn Type Cup Viscometer which are used to measure the flow behavior of liquids such as paints and is in very nice condition. Applicable to the construction site to quickly measure the viscosity of the paint to be sprayed; more widely used in electronic products, plastic coatings industry.
- Fast determination of fluid viscosity such as ink, paint and dye.
- Cup 1# ~ 5 # available for different materials
- Mainly applied to maintain the stability of the viscosity of the product in the process of use, so that the viscosity is always maintained at the set range to protect the color of the product effect.
Clear Nameplate
Laser marking of nameplates of various models is convenient for different use.
Outflow Hole
Precision drilling can ensure the accuracy of outflow, is not easy to grind.
Balance Ring Buckle
Ensure that the cup body remains vertical during use, easy to operate, fast and accurate measurement.
Zahn Cup Operation Method & Maintenance
1. Clean before Testing
Choose the appropriate cup size before testing, so that the time of outflow can be controlled between 20 and 80 seconds. Wipe it clean with the appropriate solvent and dry it before using.
2. Liquid Temperature Control
Adjust the temperature of the filtered sample and the outlet cup to 25℃ or a specific temperature, keep the temperature constant, and immerse the cup in the container for 1-5 minutes to achieve a thermal balance.
3. Test and Time
Lift the cup vertically from the sample, and the movement needs to be fast and steady. Start the timer when the the upper end of the cup leaves the liquid level and. Keep the cup vertical when the liquid flows out and the distance from the liquid surface should not exceed 150mm.
4. Viscosity Value Conversion
Stop timing when the first breakpoint occurs. Repeat the test 2-3 times. Take the average time to reduce the error and the difference between the two measurements should be less than 5% of the average. Then use the formula v=k (t-c) to convert the viscosity value. Clean the cup after testing.
Application
Zahn Cup can be used to quickly determine the viscosity of printing ink, dyes, coatings, experimental solvents, leather paint, oil, grease, food and other mobile liquids in the printing industry such as paint, varnish, wet enamel, gravure, relief, lithography, flexography, silk plate, etc.
Zahn Cup is often used as a fast viscosity measuring tool in workshops and at the spot.

When you have to scoop up the gloop to watch the gloop droop.Except no substitute.

Very nice craftsmanship. Exactly what I was expecting to get. I used these when I mixed paint as a body man. Now I use this one to measure the viscosity of my home made hot sauce!

Just what we needed to measure liquid viscosity in our lab

We are always looking to curb costs in our company, so we purchased this to monitor our oil voscocy in our machinery. We will now do monthly check. Change filters more often. And in the long run save money.

This is a great quality #5 Zahn cup! It's easy to use and stainless steel, so it should last forever and it's easy to clean. This is an essential tool when thinning paint for use in a sprayer as it's crucial to have the right viscosity. It's on the pricey side, at around $27.50, but you get what you pay for, and one thing I've learned in all my years of DIY painting projects is to not cheap out on the brushes or tools! This is a great product at a good price.

I've been using the plastic viscosity Cup that came with my sprayer years ago. Spray a lot of enamels and trying to clean a plastic Cup without melting it with solvents it's not an easy task. With time the whole gets distorted and is no longer accurate. These stainless-steel viscosity cups are beautifully made. Are easy to clean with any solvent necessary without damaging the tool. If you're doing any kind of spray application, I highly recommend this tool in order to get the viscosity right for a quality finish.
