Review: プラスチック製のボタン - プラボタンの感触が好きです。 Review: 20年以上愛用してます - 土木施工管理の仕事をしております。 20年以上前に海外で仕事をする機会があり、現地で購入しましたが、それ以来ずっと使っております。(15年ほど使って液晶が少し見にくくなってきたので同じ機種を買って継続して20年超です) 必要最低限な機能は備わっておりますし、数値記録機能、計算を遡って表示する機能など重宝しております(日本の関数電卓にも同じ機能はあるのかもしれませんが…) 他の方も書かれてますが、電源を切っても前の計算記録が残ってるのもありがたいです。 アメリカで買えば安いのかもしれませんが円安の昨今この値段で買えるのはありがたいです。 ## Features - テキサス・インスツルメンツ（TI）製のプロ仕様の関数電卓。二行表示。 - テキサス・インスツルメンツは、世界的な半導体開発・製造企業です。本社はアメリカ・テキサス州ダラスにあります。略称は「TI」。 - シンプルで洗練された長く使いやすいデザインです。 - 色：黒/ブラック サイズ:約15.5×8×2㎝ 重さ:約170g - 大きな表示板で、数値が見やすい作りです。高度な機能を兼ね備えています。本格的な関数電卓です。 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00000JBNX | | Amazon Bestseller | #33,089 in Office Products ( See Top 100 in Office Products ) #20 in Scientific Calculators | | Batteries Included | Yes | | Batteries Required | Yes | | Brand | Texas Instruments | | Color Name | black | | Customer Reviews | 4.8 4.8 out of 5 stars (47,694) | | Date First Available | August 6, 2012 | | Display Size | 3 | | Display Type | LCD | | Included Components | … | | Item Model Number | 30XIIS/TBL/1L1/BK | | Item Weight | 6.2 Ounces | | Item model number | 30XIIS/TBL/1L1/BK | | Manufacturer | Texas Instruments | | Material | Plastic Metal | | Model Year | 2008 | | Product Dimensions | 15.49 x 8.13 x 1.88 cm; 175.77 g | | Release date | June 1, 2019 | | Size | 1 Pack | ## Product Details - **Brand:** Texas Instruments - **Calculator Type:** Engineering/Scientific - **Color:** black - **Power Source:** Solar Powered - **Screen Size:** 3 ## Images ![Texas Instruments 30XIIS 関数電卓 並行輸入品 - Image 1](https://m.media-amazon.com/images/I/71UoB-VmSyL.jpg) ## Questions & Answers **Q: Is there a cover for this one, I do not see one shown?** A: As of July 2022, it does come with a cover. **Q: What type of battery?** A: It is both solar and battery powered. I have had mine for 22 years and have never needed a new battery. The batteries power is restored by the solar. If you think you need to replace the battery it can be replaced on the back of the calculator with 4 small screws. Not sure of the type since I have never had to replace mine but you can look there. **Q: Does it come with a hard cover?** A: Yes, It does come with hard cover **Q: If you attempt a square root that is not a perfect square will it simplify or not? (I.E. square root of 45) I need to know this for my finals.** A: Ms. Fitzpatrick, your question concerning the TI-30X IIS is "Will it simplify (e.g. square root of 45)?" The short answer is NO. The TI-30X IIS will display 6.708203932 for the square root of 45.The square root of 45 in its simplest radical form is/would be 3ã5. However, the TI-30XS will display 3ã5 as a resultant of square root of 45. I hope this helps.Respectfully,Mike ## Customer Reviews ### ⭐⭐⭐⭐⭐ プラスチック製のボタン *by H***K on 2025年7月5日に日本でレビュー済み* プラボタンの感触が好きです。 ### ⭐⭐⭐⭐⭐ 20年以上愛用してます *by に***き on 2025年2月11日に日本でレビュー済み* 土木施工管理の仕事をしております。 20年以上前に海外で仕事をする機会があり、現地で購入しましたが、それ以来ずっと使っております。(15年ほど使って液晶が少し見にくくなってきたので同じ機種を買って継続して20年超です) 必要最低限な機能は備わっておりますし、数値記録機能、計算を遡って表示する機能など重宝しております(日本の関数電卓にも同じ機能はあるのかもしれませんが…) 他の方も書かれてますが、電源を切っても前の計算記録が残ってるのもありがたいです。 アメリカで買えば安いのかもしれませんが円安の昨今この値段で買えるのはありがたいです。 ### ⭐⭐⭐⭐⭐ 日本では正規購入ルートがない *by 東***鶏 on 2016年3月4日に日本でレビュー済み* とても3,000円する物の質感ではないのは仕方なし（実売$15以下）。見た目は標準的な数式入力二段表示。しかしマイナスと演算子のマイナスが厳密に区別されるなど、仕様を解ったうえで使うとこのキー配置など日本製電卓と違う思想を感じられてとても良い。計算履歴が電源切っても残っているのは試験対策にこの記憶機能がわざと搭載されていない日本製関数電卓と違ってものすごく便利。 ## Frequently Bought Together - Texas Instruments TI-30XIIS Scientific Calculator, Black with Blue Accents - BIC Brite Liner Highlighters, Chisel Tip, 5-Count Pack of Highlighters Assorted Colors, Ideal Highlighter Set for Organizing and Coloring - Five Star Spiral Notebooks + Study App, 4 Pack, 1 Subject, College Ruled Paper, 8-1/2" x 11", 100 Sheets, Purple, Pink, White, Green (820337-ECM) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/737434861-texas-instruments-30xiis-関数電卓-並行輸入品](https://www.desertcart.at/products/737434861-texas-instruments-30xiis-関数電卓-並行輸入品) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-02*
