A&D GX-303A - 320g x 0.001g Precision Balance with Internal Calibration

A&D GX-303A pairs precision and protection in one rugged benchtop balance. Ideal when weighing sensitive materials in high-risk environments or weighing with automated devices. 

Constructed in die-cast aluminum with a stainless steel weighing pan. Security slot in the rear for an anti-theft lock.GLP/GMP/GCP compliant with full calibration reports. Password-Protect offers password-protection up to 11 users and 1 administrator.  

Easy calibration with one touch button - GX-303A performs and documents internal calibration and features Automatic Self-Calibration (ASC) – the balance auto calibrates based on temperature and time interval. Enabled by the Smart Super Hybrid Sensor (SHS) technology for superior accuracy and fast stabilization of approx. 1 second.

Features Impact Shock Detection, Flow Rate Display and Electronically Controlled Load (ECL). This unique combination of features enhances precision, reducing the amount of rework required and lowering costs.

Features:

  • Large, front-mounted spirit level with LED illumination, easy-to-adjust leveling feet with thumbwheels. Clearly visible, reverse backlit LCD display

  • 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. 

  • Underhook for weighing a magnetic material and/or measuring density

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.

⭐⭐⭐⭐⭐ Clean Look, Comfortable Ride
Size: 11.5 Wide, Color: Woodbury Handstain
The Cole Haan Men’s GrandPro Tennis sneakers are a perfect mix of laid-back and polished — the kind of shoe you can wear everywhere without thinking too hard about it. Right off the bat, the design is subtle but refined. They’re minimalist enough to pair with jeans and a hoodie, but they also work with chinos and a button-down for a more put-together look. The “tennis” aesthetic keeps it classic without feeling like you’re wearing athletic shoes. Comfort is where these really shine. They’re lightweight and cushioned in all the right places, so long walks, errands, or standing around at events don’t end with sore feet. There’s no stiff break-in period — they feel good from the first wear. The sole has just the right balance of support and flexibility, which makes them easy to wear all day. The materials feel good too — soft, sturdy, and not flimsy. They hold up well after repeated wear and still look fresh even after a few outings. They don’t crease or scuff up excessively, which is always nice. If I had to point out a downside, it’s that they’re not performance sneakers for athletics — but that’s not what they’re meant to be. They’re lifestyle shoes that look great and feel great for everyday wear. Overall, a solid go-to sneaker that elevates casual outfits and keeps comfort front and center. Easy recommend if you want versatile kicks that stay stylish without being loud. I was able to pick up this particular pair here on Amazon for 50 bucks, 56 total with everything and honestly I’m still scratching my head in that deal. I mean my New Balance were 70 bucks or something like that. These are brown leather, sophisticated and comfortable, just amazing shoes. I get compliments all the time.

Size seems spot on shoe is beautiful
Size: 12, Color: White
These are beautiful shoes. A great cross between the ubiquitous flat as a board shoes like vans and tennis shoes. More comfortable than the super flat shoes and more formal than sneakers. Very soft leather. Not much arch support and I don't know if an insert would fit well. I am between an 11.5 and 12 in most brands (actual foot length from heel to tip of big toe is 11 and 1/8 inches). These fit perfectly in a 12 with room for comfort. An 11.5 probably would fit but snugly. I do not agree that they should be sized down at least based on my experience. If you can get these for under eighty dollars like I did they are well worth it. I'll be wearing them all summer.

Weightless, well made. But there are problems with size
Size: 8.5, Color: White
I bought it for a teenager, for size 81/2. This, according to the dimensions on the page, is 25.9 centimeters. They came, the size was indicated correctly, but they are large for the child. Very large. They fit me, size 10. The child is disappointed. Well made, look neat on the foot. Almost weightless But I can't give the maximum rating. I wish the seller to deal with the size grid.
