We grade equipment the way a journal grades evidence. Here is the durability-portability-suitability rubric behind every recommendation.
International Health Journal came out of a peer-reviewed tradition, and the editorial instinct it kept is simple: grade against evidence, not against marketing. Applied to equipment, that instinct becomes a three-part rubric we run before any recommendation — durability, portability, and field-suitability.
Durability asks whether the item survives transport shock, heat, dust, and the maintenance reality on the ground. Portability asks whether it can reach the last mile inside the program’s logistics envelope. Field-suitability asks whether it is the right instrument for this deployment, operable by the people who will actually run it. Price enters only after all three are satisfied. For the full specification, see our guide to field equipment sourcing advisory.
This rubric is deliberately resistant to spec-sheet seduction. A superior cooling curve, a sharper image, a higher protection rating — none of it counts if the instrument dies in month three or cannot be repaired in the field. The grade reflects field performance, not catalog performance.
The rubric is also the backbone of our sourcing advisory: the same method that grades a guide grades your manifest. It is field-tested judgment, disclosed as such, and it is what every recommendation on this site rests on.
