Interpretive Summary: Micronaire is an important fiber quality parameter in the cotton and textile industry. Fiber micronaire is a function of maturity (the degree of the fiber secondary wall development) and fineness (linear density). Bench-top near infrared (NIR) spectroscopy has the ability to measure micronaire, maturity and fineness, in and out of the laboratory. Small portable handheld NIR instruments have been introduced, and a program was established to measure micronaire in and outside the laboratory on seed cotton fiber and cotton lint, and consequently to measure maturity and fineness in the fiber, using small portable handheld NIR instruments. Adding new data to the original commercial lint-only samples, including data from different environments (laboratory and greenhouse) and fiber type conditions (laboratory ginned lint and seed cotton) made the calibration more robust, increasing the accuracy two NIR instruments (MicroNIR 2200 and Luminar 5030). Each instrument has its individual strengths, and it is advisable to use the instrument that best fits the laboratory research objectives.
