Small Instrument Case: confirm internal dimensions first (equipment size plus foam allowance), then protection rating (IP67 is the benchmark) and shell material (PP for value, ABS for surface hardness, rotomolded PE for large sizes). Custom sizes available via tooling.
An instrument case protects precision measuring and testing equipment in transit, emphasizing shock absorption, moisture resistance and custom foam so instruments stay calibrated between lab and field.
Small Instrument Case: Product & Manufacturer Overview
From total stations and spectrometers to flaw detectors, kexinMaterials has built the Small Instrument Case for thousands of instrument models, with an insert database spanning surveying, environmental monitoring, NDT and telecom engineering.
For buyers, the true cost of a Small Instrument Case is more than unit price: carton specs shape freight, and spare parts and replenishment shape long-term use. kexinMaterials optimizes container loading and ships wear-part kits with volume orders to lower your total cost of ownership.

How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Protection | IP67, thermal-shock verified -40°C↔+71°C | Plain cases fail thermal shock |
| Damping foam | EVA/PU/XLPE CNC-cut to instrument shape | Generic foam under-cushions |
| ESD & clean | Optional anti-static liner, non-shedding XLPE | Sheds debris onto optics |
| Rigidity | ABS high surface hardness, high crush strength | PP softens under stacking |
| MOQ | From 50 pcs, non-standard sizes toolable | Often 500 pcs min |
| Certification | Drop/vibration test reports provided | Incomplete docs |
Portability: compact models are weight-optimized without sacrificing structure — one-hand carry, with strap and belt-mount options for personal and field use.
Standards & Industry Data
Military Vibration (MIL-STD-810H, Method 514.8)
Random-vibration testing spans 20–2,000 Hz to replicate truck, aircraft and battlefield vibration, run for hours per axis; transport spectra cover 2–500 Hz. Passing means the shell-plus-foam system protects precision payloads through long multimodal transit.
Extreme Temperature Performance
Engineering-grade cases typically operate from -30°C to +80°C (military testing follows MIL-STD-810H Methods 501.7/502.7 for temperature and 503.7 for thermal shock, cycling as wide as -40°C↔+71°C). For cold climates choose PP copolymer or PE shells — standard ABS embrittles at low temperatures.
IP Ratings (IEC 60529)
In IP67, the “6” means dust-tight (no dust ingress after a 2 kPa vacuum dust test) and the “7” means temporary immersion: the enclosure survives 30 minutes at 1 m depth with its highest point at least 150 mm below the surface, per IEC 60529 Clause 14.2.7.
Typical Applications
- Surveying instrument field carry
- Third-party lab on-site sampling
- Metrology equipment calibration logistics
- Fiber-optic construction toolkits
- Laboratory relocation and equipment loans
- Manufacturer co-packing programs
Sizing & Selection Guide
To size a Small Instrument Case, measure the largest 3D dimensions of the payload and allow 30–50 mm per side for foam, then match against internal case dimensions. Above 30 kg payloads, add wheels and reinforced bases.
kexinMaterials stocks a full size run from personal cases to large transit trunks with published internal dimensions; if nothing fits, we evaluate mold revisions or new tooling — selection advice is free.
Manufacturing Process
High-pressure injection molding keeps shell tolerances tight for reliable sealing, and inserts are CNC-cut after drop-simulation checks. Volume co-packing projects follow a PDI inspection routine so cushioning performance stays consistent across batches.
Field Case Studies
600 anti-static liner cases for precision calibrators using non-shedding XLPE; zero scratch incidents in annual off-site checks.
3,000 cases CNC-cut to probe shapes, thermal-shock verified -40°C↔+71°C, protecting gear across overseas expos.
