Portable soil-sampling-case from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 30, 12h quote, 30-day delivery to 47 countries.
What does Portable soil-sampling-case actually deliver? 1.2m concrete drop, 30 minutes at 1m underwater, -40 to +80°C, 5,000 latch cycles. We can show you the test videos and the SGS certificates.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP | Multimeter / Caliper |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+AS | Surveying Total Station |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+AS | Optical Microscope |
The most common model for "Portable soil-sampling-case" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Portable soil-sampling-case uses 25 kg/m³ foam rated for 5+ year use. The difference is in the cell structure: 25 kg/m³ cells rebound after compression, 15 kg/m³ cells do not. We have tested both. The cheaper foam fails.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Here are 3 real Portable soil-sampling-case foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries — fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger — fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables — fits WL5020. We share these at the 12h quote stage.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
