2 Quality Authentic quality
Excellent quality and authentication ensure confidence and peace of mind for use in educational settings
CASIO has established three criteria to ensure excellent quality in the MS series.
2,000-cycle wear testing
Since these calculators are products used as educational tools for long periods of time, materials that ensure robust key durability and prevent wear or fading of key markings are used to ensure product quality.
Drop testing from a height of 75 cm
High product quality prevents key malfunction due to drop impact if a calculator falls to the floor from a desk in the classroom or display (LCD) or key breakage if a calculator is accidentally crushed in a schoolbag.
Compliant with RoHS environmental regulations
The materials used in MS series calculators comply with European RoHS environmental regulations, an international standard. The product quality reflects concern for health and the environment.
