LEAT-4 Thermal Conductivity Measurement Apparatus
Main technical nta:
1. Nws txais cov cua sov uas tsis muaj hluav taws xob sib cais, uas muaj kev nyab xeeb thiab siv tau yooj yim;
2. Siv lub teb chaws tus qauv thermocouple ntsuas kub thiab Teflon hloov tau yooj yim tiv thaiv raj, lub thermocouple tsis yooj yim tawg;
3. Lub peev xwm thermoelectric ntsuas los ntawm kev ua haujlwm siab sab hauv, siab precision, qis drift amplifier thiab peb thiab ib nrab digital voltmeter;
4. PID kub tswj cua sov yog siv los tswj qhov kub thiab txias ntawm lub phaj tooj liab thiab txhim kho qhov tseeb ntawm qhov kev sim.
Main technical parameters:
1. Digital voltmeter: 3.5 ntsis zaub, ntau yam 0 ~ 20mV, ntsuas qhov tseeb: 0.1% + 2 lo lus;
2. Digital stopwatch: 5 tus lej nres nrog qhov kev daws teeb meem tsawg kawg ntawm 0.01s;
3. Kev tswj qhov kub ntawm qhov ntsuas kub: chav ntsuas kub ~ 120 ℃;
4. Cua sov voltage: siab kawg ac36v, qis kawg ac25v, cua sov zog txog 100W;
5. Thaum tshav kub kub dissipation tooj liab phaj: vojvoog 65mm, thickness 7mm, loj 810g;
6. Cov ntaub ntawv xeem: duralumin, silicone roj hmab, roj hmab board, cua, thiab lwm yam.
7. Lub thermocouple freezing point them Circuit Court yuav muab ntxiv kom txuag tau qhov teeb meem ntawm kev siv dej khov sib tov;
8. Lwm qhov ntsuas kub tuaj yeem siv los ntsuas qhov ntsuas kub, xws li PT100, AD590, thiab lwm yam.
