The Leeb 250 series represents a comprehensive range of coating thickness gauges, with the flagship 253 model specially designed for fireproof coating measurement up to 6000μm, while other models measure up to 1250μm. The series features integrated probes for compact design (150×55.5×23mm) and simplified one-button operation through an English menu interface. Model 252 offers dual measurement principles (magnetic induction and eddy current), while the 250A includes USB connectivity and advanced data management with 320-measurement storage capacity.
Built for efficient field deployment, these lightweight (120g) instruments operate on AAA alkaline batteries and maintain accuracy of ±[(1-3%)H+1] with 1μm resolution. The series performs effectively in temperatures from 0°C to 40°C with 20-90% humidity tolerance, handling curved surfaces with minimum radii of 1.5mm convex and 20mm concave. Each unit includes comprehensive calibration capabilities with five specimens (50mm-1000mm) and supports statistical analysis including mean, maximum, minimum values, and standard deviation.
