Dial Caliper
Precision measuring instrument designed for accurate measurement of grain and seed dimensions such as length, width, and thickness, ensuring reliable quality analysis.
What is Dial Caliper?
The Dial Caliper is an essential metrology tool utilized in agricultural laboratories and commercial milling facilities to meticulously measure the physical dimensions of seeds, grains, and mechanical processing components.
Operating via a precision rack-and-pinion gear system, it translates minor linear movements of the measuring jaws into an amplified, easily readable rotation on a high-contrast analog dial. For B2B agricultural applications—particularly in rice and grain processing—this instrument is indispensable for determining the exact Length-to-Width (L/W) ratio of kernels, evaluating bran thickness, and classifying commodities into standard commercial grades (e.g., long, medium, or short-grain).
By providing instant, highly repeatable measurements without the need for power or digital calibration, it allows facility managers and agronomists to maintain unwavering quality control directly on the processing floor or in the analytical laboratory.
Common Applications
Commercial Rice & Grain Mills
Used to determine exact kernel dimensions and L/W ratios for premium basmati or short-grain commercial grading.
Seed Testing Laboratories
Essential for establishing the physical uniformity and structural dimensional profiles of newly developed seed cultivars.
Grain Procurement Terminals
Empowering procurement inspectors to rapidly verify grain size consistency against strict international export specifications.
Milling Machinery Maintenance
Critical for engineers and technicians when adjusting precise roller clearances on industrial dehusking and polishing equipment.
High-Resolution Analog Dial
Features a high-contrast, anti-glare dial face driven by a precision rack-and-pinion gear system. This provides technicians with instant, highly visible readouts, significantly speeding up high-throughput grain sorting workflows without relying on battery-powered digital screens.
