以下是一份關(guān)于3404轉(zhuǎn)速計(jì)的產(chǎn)品中英文介紹：

3404轉(zhuǎn)速計(jì)是一款由日本日置（HIOKI）公司生產(chǎn)的精密測(cè)量儀器。它具有高分辨率0.01rpm和高精度±1dgt，能夠有效地進(jìn)行準(zhǔn)確測(cè)量。該轉(zhuǎn)速計(jì)使用選件9213接觸轉(zhuǎn)換器，可變成接觸式的轉(zhuǎn)速表，旋轉(zhuǎn)時(shí)可以像測(cè)量線速度一樣應(yīng)用。其測(cè)量模式豐富，包括最大/最小、總和、周期、快/慢采樣、模擬輸出等多種模式。

在技術(shù)參數(shù)方面，3404轉(zhuǎn)速計(jì)的測(cè)量量程為r/min：(30.00～199.99)量程至(20000～99990)量程，4檔（慢速采樣模式）；r/s：(0.5000～1.9999)量程至(200.0～1600.0)量程，4檔（慢速采樣模式）。采樣周期分為慢速0.5s～2s，快速0.1s～0.5s。探測(cè)距離為50mm～200mm，模擬輸出為直流1V滿量程輸出。電源供應(yīng)可選擇R6P（AA）×4（連續(xù)使用16小時(shí)）或AC電源轉(zhuǎn)換器（6V,300mA）。它的體積小巧，重量輕，尺寸為62寬×180高×38厚mm，重量僅260g，便于攜帶和操作。

3404轉(zhuǎn)速計(jì)的附件包括9211反光貼紙（1），9094輸出線（1），攜帶盒（1）。此外，還有可選附件，如9211反光貼紙（10張、每張10片，每片12×12mm），9213接觸式轉(zhuǎn)換器（附9032、9033×2、9212），9212滾輪式接觸頭，9032金屬式接觸頭，9033橡膠式接觸頭。

在價(jià)格方面，3404轉(zhuǎn)速計(jì)的價(jià)格因銷售渠道和購買數(shù)量等因素會(huì)有所不同。一般來說，其價(jià)格在數(shù)千元人民幣左右。具體價(jià)格可咨詢相關(guān)經(jīng)銷商，如上海樹信儀器儀表有限公司、廈門欣銳儀器儀表有限公司等。

The 3404 tachometer is a precision measuring instrument produced by HIOKI, a Japanese company. It features a high resolution of 0.01rpm and high accuracy of ±1dgt, enabling effective and accurate measurements. With the optional 9213 contact converter, the 3404 tachometer can be transformed into a contact tachometer. When rotating, it can be applied like a linear speed measuring instrument. The 3404 tachometer offers a variety of measurement modes, including maximum/minimum, total, period, fast/slow sampling, and analog output.

In terms of technical specifications, the 3404 tachometer has a measurement range of r/min: (30.00～199.99) to (20000～99990) in four ranges (slow sampling mode); r/s: (0.5000～1.9999) to (200.0～1600.0) in four ranges (slow sampling mode). The sampling cycle is divided into slow 0.5s～2s and fast 0.1s～0.5s. The detection distance is 50mm～200mm, and the analog output is a direct current of 1V full-scale output. The power supply can be chosen between R6P (AA) ×4 (continuous use for 16 hours) or an AC power converter (6V, 300mA). The tachometer is compact and lightweight, with dimensions of 62mm wide × 180mm high × 38mm thick and a weight of only 260g, making it easy to carry and operate.

The accessories of the 3404 tachometer include 9211 reflective tape (1), 9094 output cable (1), and a carrying case (1). In addition, there are optional accessories such as 9211 reflective tape (10 sheets, each with 10 pieces, each piece 12×12mm), 9213 contact converter (with 9032, 9033×2, 9212), 9212 roller contact head, 9032 metal contact head, and 9033 rubber contact head.

Regarding price, the price of the 3404 tachometer varies depending on the sales channel and the quantity purchased. Generally, its price is around several thousand yuan. The specific price can be inquired from relevant dealers, such as Shanghai Shuxin Instrument Co., Ltd and Xiamen Xinrui Instrument Co., Ltd.
