Casio Scientific Calculator fx-991MS 2nd edition (Non-programmable)

Excellent quality and authentication ensure confidence and peace of mind for use in educational settings

Excellent quality

CASIO has established three criteria to ensure excellent quality in the MS series.

• 1. Wear-resistant printing:

  • 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.

• 2. Drop-resistant body

  • 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.

• 3. Environmentally friendly

  • 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.
