LH-PH10/20/30 PHPen tester
Economy hnab tshos pH tester, 2 ntsiab lus calibration, Tsis Siv Neeg Kub Txias Txias.Lub 'meter' yog haum rau ntsuas pH ntawm cov kua, qhov tseeb: 0.01pH.
1) LH-PH10 16-ntsis, LH-PH20/30 32-ntsis MCU khiav ntawm kev kub ceev, thiab kev ntsuas ceev ceev;
2) Ua raws li cov qauv kev ntsuas hauv tsev thiab txawv teb chaws;nws tus kheej tsim software thiab kho vajtse;0.01PH thiab 0.1 ° C / ° F qhov tseeb lav;
3) Tag nrho cov series txais kev kuaj-theem sensors, uas yog piv rau non-universal sensors;Cov khoom siv hluav taws xob zoo thiab NTC cov khoom siv ntsuas kub yog siv los xyuas kom muaj kev ruaj ntseg ntsuas;
4) LH-PH20/30 muaj lub buzzer ceeb toom muaj nuj nqi kom nco ntsoov koj thaum lub hwj chim rau, ntsuas tus nqi yog ruaj khov, calibration tiav, thiab lub khawm ua haujlwm muaj lub suab ceeb toom;
5) AAA (No. 7) roj teeb lub zog, hloov tau yooj yim dua;
6) Tag nrho cov cim zaub, cov ntawv qhia meej dua thiab cov kev xaiv pom tseeb (LH-PH20/30);high-contrast LCD multi-cov ntaub ntawv tso saib ntawm tib lub vijtsam, softer txiv kab ntxwv backlight, LH-PH30 txhawb kev hloov kho ntawm ntau xim tus kheej backlight kev nthuav qhia.
