中文介紹
Testo 511 是一款便攜式絕對(duì)壓力測(cè)量?jī)x器，具有高精度和多功能的特點(diǎn)。它主要用于測(cè)量絕對(duì)壓力，例如在風(fēng)管、實(shí)驗(yàn)室和生產(chǎn)過(guò)程中的流量測(cè)量中進(jìn)行密度補(bǔ)償。此外，該儀器還可以計(jì)算氣壓和測(cè)量海拔高度。
Testo 511 的設(shè)計(jì)非常小巧便攜，重量?jī)H為 90 克，尺寸為 119×46×25 毫米。它配備了背光顯示屏，即使在光線較暗的環(huán)境中也能清晰讀取數(shù)據(jù)。該儀器的測(cè)量范圍為 300 到 1200 百帕，精度可達(dá) ±3 百帕。它還支持 8 種不同的壓力單位，包括 hPa、mbar、Pa、mmH₂O、inH₂O、inHg、mmHg 和 psi。
Testo 511 的操作非常簡(jiǎn)便，用戶(hù)只需輸入現(xiàn)場(chǎng)海拔高度，即可將絕對(duì)壓力讀數(shù)轉(zhuǎn)換為氣壓。此外，該儀器還配備了保護(hù)帽、腕帶和腰帶夾，方便用戶(hù)在各種場(chǎng)合使用。其電池續(xù)航時(shí)間長(zhǎng)達(dá) 200 小時(shí)，能夠在 0 到 50 攝氏度的溫度范圍內(nèi)正常工作。

English Introduction
The Testo 511 is a portable absolute pressure meter known for its high precision and versatility. It is primarily used for measuring absolute pressure, for example, for density compensation in flow measurements in ducts, laboratories, and production processes. In addition to this, the instrument can also calculate barometric air pressure and measure altitude.
Designed to be compact and easy to carry, the Testo 511 weighs only 90 grams and measures 119×46×25 millimeters. It features a backlit display that ensures clear readings even in low-light conditions. The device has a measuring range of 300 to 1200 hPa with an accuracy of ±3 hPa. It supports eight different pressure units, including hPa, mbar, Pa, mmH₂O, inH₂O, inHg, mmHg, and psi.
The Testo 511 is user-friendly. By entering the on-site altitude, users can easily convert the absolute pressure readings to barometric air pressure. The device also comes with a protective cap, wrist strap, and belt holder for convenient use in various settings. With a battery life of up to 200 hours, it can operate effectively within a temperature range of 0 to 50 degrees Celsius.
