The 5400FW now includes Vapor Pressure Deficit (VPD). VPD quantifies the gap between the moisture currently in the air and the maximum moisture the air can hold at saturation. This measurement reveals the atmosphere’s drying potential—one of the most important drivers of fuel moisture (FM). Because FM is fundamental to wildfire behaviour and management, being able to estimate it accurately in the field—without relying on time-consuming laboratory analysis—marks a major operational advancement.\u003c\/p\u003e\n\u003cp\u003eLightweight and simple to use, with a large sunlight-readable graphing display.
