High-precision, fast, flexible and easy!.The LabMaster-aw is the only instrument in the world that enablesmeasurements under precisely controlled chamber temperatureconditions, selectable in the following range: 0°C to 50°C, with a precision of 0.2K. His quick response and many additional software features set the new standard for aw-value measurement.
A new multi-user and multi-probes management is implemented and fulfils the first time ever all subjects of regulation or recommendations of different associations and laws.
The large, clear illuminated graphic LC display is very easy to read and the menu driven software is intuitive and simple to learn.An RS 232 or USB interface is implemented for connecting a printer or PC.PC-Software for Win9x/2000/NT/XP is provided with the instrument.
Examples of aw measurements: All forms of pastry and baked goods Meat and sausages Fruit concentrates Cheese, Milk products Dried foodstuffs Pasta, Icecream Medications Cosmetics, Lipsticks

產(chǎn)品介紹水份活度(Water Activity)主要反映物料平衡狀態(tài)下的水分狀態(tài)。各種微生物的活動(dòng)和各種化學(xué)與生化反應(yīng)都有一定的AW閾值,因此AW影響生物制品的營(yíng)養(yǎng)、風(fēng)味、色澤、質(zhì)構(gòu)、流變特性及微生物生長(zhǎng)。測(cè)定AW值可以判斷產(chǎn)品的貨架壽命,選擇合理的儲(chǔ)藏條件和包裝材料。
聯(lián)合國(guó)糧農(nóng)組織和世界衛(wèi)生組織(FAO/WHO)藥物和食品委員會(huì)、U.S食品和藥物管理局、日本食品衛(wèi)生法規(guī)等都將AW作為某些食品的控制性指標(biāo)。HA1-AW-1型智能水分活度測(cè)定儀由高精度傳感器采樣,單片機(jī)為核心,進(jìn)行信號(hào)采集和處理,并用標(biāo)準(zhǔn)鹽飽和溶液分段校準(zhǔn)。它具有測(cè)量精度高,測(cè)量時(shí)間短。該機(jī)工作穩(wěn)定,操作簡(jiǎn)便,主要技術(shù)指標(biāo)均達(dá)到國(guó)外同類產(chǎn)品的水平,具有較高的實(shí)用價(jià)值。AW測(cè)量范圍:0.000~1.000
