Why don't you carry the hard shell & padded case - Model #MA800

We do. It's just that they use the same UPC code for both and Amazon doesn't recognize the difference. Give us a call for that one.

How do you clean it, after each use? Just rinse it out?

I've always just dried it with a cloth or paper towel. Anything really. Been doing it for years

Is there a difference between the green or black version of the milwaukee ma887 digital salinity refractometer?

No, the "black" version is the latest Milwaukee product cc 2021. Functionally they are exactly the same. Dittio for the other Milwaukee products too.

I've had my ma887 for year now. seems to calculate 35ppt at 1.027 s.g. anyone else's unit do this?

I have had the same problem and you can calibrate it with distilled water, but mine was still off by 2ppm regardless.

Was mad at first

When I recieved it, I calibrated it with the calibration solution, then tested the test solution, it kept giving me 1.024 instead of 1.025, today I calibrated it again and it was reading 1.025, not sure what changed, I am guessing the temperature of the machine and solutions, when it arrived everything was warm from being in the car I guess

Great device, if you are keeping Reef aqurium you should have one. Works as advertised, extremely easy to use, come with 0ppm calibration solution and 35ppm controll sample, 2 pipets for sampling + batteries for device it self. Not cheapest option on the market but with high value corals in our tanks price is comparable to brand name see true type refractometers. Highly recommended!!!

Doesn’t look like a new item

Box was crushed and there was scratch mark on the product. Test solution was leaking. Looks like a used product which isn’t acceptable for the price.
