  • User access control (UAC) function that password-protects the balance at two  levels.  Key lock function to make the balance operable only by sending commands from an external device

  • Data memory function: save weighing results, calibration results and unit masses for the counting mode in the device itself. Tare memory function that saves the tare value in non-volatile memory

  • Alert function to ensure that the measured quantity is not smaller than the set minimum weight. 

  • Universal Flexi Coms (UFC) function to edit serial data output/printout format

  • Clock and calendar function, Auto power ON and OFF functions.

Impact Shock Detection (ISD)
  • Impact-Alert – displays the magnitude of impact shocks to the weight sensor at four levels, with audible notification for higher levels of impact which should be avoided

  • Shock-log that records time, date, shock level and operator ID, making quality control easier to pinpoint. 

  • Real-time feedback mechanism prevents equipment damage, and allows managers to modify in-line or manual processes alike. An important feature when transverse and vertical environment forces are unpredictable.

Electronically Controlled Load (ECL) 

Allows the user to perform a diagnostic check and repeatability test without the need of an external test weight

  • At the touch of a button and in under two minutes, users gain a daily precision verification test with Dia-Check.
  • Determine a standard deviation and calculate the minimum sample weight with Quick-MinS, and ensure operations are USP41 compliant with Min-S-Alert.
  • Ensures critical measurements are compliant with industry standards such as USP 41 and 1251.
Flow Rate Display (FRD)

  • The FR-Calc feature calculates and displays the mass or volume flow rates to close the “time-clock disparity” found with traditional PC methods.

  • FR-comparator, which allows monitoring of flow rate data to ensure it is kept within designated limits

  • Tare value can be saved in non-volatile memory so that the remaining amount of the material in the container can be displayed again, even if power is disrupted during loss-in-weighing measurement.

Durable
Color: Nude, Size: Women 9-13
These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.

Great Results
Color: White, Size: Women 9-13, Color: White, Size: Women 9-13
The Jfrhuds Moisturizing Silicone Socks work very well. I ordered the white 2-pack in the large size 9-13, and each came packaged in an individual zipper bag.  I wear a women's size 9-9.5, and they fit me perfectly.  I can see how they have enough stretch to fit larger sizes easily and comfortably. These socks are a lot thicker and heavier than I expected.  They are rubbery with non-slip treads on the bottom.  As soon as I put them on my feet, they actually felt very moisturizing and almost wet, even though I had not put moisturizer on my feet first.  Plus my feet felt cold at first. It was different than I expected, I had never worn this type of sock before, and it was an interesting sensation. They work great, and I am sold on the benefits of these socks.  I wear them to sleep at night and dodn't walk very far in them.  They seem pretty sturdy, but I don't want to push it and will just use them for their intended purpose.  My feet weren't super dry or cracked, but the socks really helped revive them and make them super soft again.  I love them; they are great for self-care and would also make a wonderful gift.

Not durable
Color: Nude, Size: Women 9-13
Only used two of them so far. One sock lasted nearly 3 wears. The other broke before I could finish wearing it the second time. Basically useless junk.

Thick Silicone Moisturizing Socks
Color: Nude, Size: Women 9-13, Color: Nude, Size: Women 9-13
★★★★☆ Thick Silicone Moisturizing Socks I ordered these silicone moisturizing socks to try for dry heels. Unlike typical fabric spa socks, these are made entirely of soft silicone and are noticeably thicker and very stretchy. When I first took them out of the package there was a visible fold line in the silicone. It appears to be from how they were folded in the packaging rather than a defect in the material. The silicone itself feels durable and flexible. The design works like a full silicone sleeve that traps moisturizer against your skin. I applied Aquaphor first and then slid these on so the moisture stays in contact with the skin longer. One thing I noticed right away is that the silicone feels cool when you first put them on, which is actually pretty comfortable. The bottoms have a zig-zag textured pattern that gives some grip if you need to stand briefly, though these seem better for relaxing while moisturizer absorbs rather than walking around much. The ankle opening is the tightest part of the sock. It stretches, but it’s noticeably snug compared to the rest of the silicone, which helps keep them from sliding off. For sizing reference, I wear a women’s 7.5–8 shoe and the size Large fits comfortably. There’s plenty of stretch and I can wiggle my toes easily, so they should accommodate larger feet as well. They’re also easy to clean. After using them you can simply wash them with soap and water and let them dry completely before storing or using them again. Overall these appear well made with thick silicone and plenty of stretch. If you use moisturizing socks or heel treatments, these work well for keeping lotion in place while your feet absorb it. Since this set comes with two pairs for about $10, the price seems pretty reasonable for something reusable like this.
