Evaluating Quality Control of Play-doh with the TC‑X1
Measure Samples of Every Kind and Color
Play-doh is a non-toxic and moldable material, which makes it perfect to demonstrate the capabilities of the TC‑X1. The TC‑X1 makes a side-by-side comparison of four different colors of play-doh simple: we only need to fill the petri dish to one centimeter deep and place the dish centered on the sensor. This case study shows that different play-doh containers and colors have very consistent electrical conductivity accross the different colors. This consistency indicates tight quality control is likely used in manufacturing process.
| Play-doh Color | Average Conductivity (mS/cm) | Standard Deviation |
|---|---|---|
| Purple | 32.49 | 0.60 |
| Cyan | 33.99 | 0.48 |
| Orange | 34.10 | 0.58 |
| Pink | 32.41 | 0.48 |
Measuring how concrete dries with the TC‑X1
A cleaner way to work with messy samples
A study with the TC‑X1 clearly shows the progression of electrical conductivity as Quikrete Concrete Mix cures over a period of 6 days. Curing can be affected by ambient temperature, humidity, the presence of additives, as well as other factors. Measurement by existing technology is inconvenient, time-consuming, and fraught with error as seen in contemporary studies. By comparison, taking measurements of uncured concrete with the TC‑X1 is quick and clean - practical for studies of various mixes, or even useful for studying or monitoring large infrastructure using concrete construction.
Freshly mixed Quikrete Concrete Mix, placed into a standard petri dish at a standard depth of 1.0 cm. Conductivity at time of mixing is 8.24 mS/cm.
Quikrete Concrete Mix paste 24 hours after initial mixing and added to a standard petri dish. Conductivity has already decreased to 7.16 mS/cm due to partial curing.
Quikrete Concrete Mix paste 6 days after initial mixing and partially cured in standard petri dish. Conductivity has decreased to 1.81 mS/cm – further decrease is still expected as the cure process continues.
