LEAT-4 Thermal Conductivity Measurement Apparatus
Main technical features:
1. Inotora yakatsaurwa yakaderera-voltage kupisa, iyo yakachengeteka uye iri nyore kushandisa;
2. Uchishandisa yenyika chiyero thermocouple kuyera tembiricha uye Teflon inochinjika yekudzivirira chubhu, iyo thermocouple haisi nyore kutyora;
3. Thermoelectric simba rinoyerwa nekukwirira kwemukati kuramba, high precision, low drift amplifier uye matatu nehafu digital voltmeter;
4. PID tembiricha yekudzora kupisa kunoshandiswa kudzikamisa tembiricha yekudziya yemhangura ndiro uye kunatsiridza chokwadi chekuyedza.
Main technical parameters:
1. Digital voltmeter: 3.5 bit display, range 0 ~ 20mV, kuyerwa kwechiyero: 0.1% + 2 mazwi;
2. Digital stopwatch: 5-digit stopwatch ine zvishoma kugadzirisa kwe0.01s;
3. Tembiricha yekudzora huwandu hwetembiricha controller: kamuri tembiricha ~ 120 ℃;
4. Heating voltage: high end ac36v, low end ac25v, kupisa simba pamusoro pe100W;
5. Heat dissipation mhangura ndiro: radius 65mm, ukobvu 7mm, uremu 810g;
6. Test materials: duralumin, silicone rabha, rubber board, mhepo, nezvimwewo.
7. Thermocouple freezing point compensation circuit inogona kuwedzerwa kuchengetedza dambudziko rekushandisa musanganiswa wemvura yechando;
8. Mamwe ma sensor tembiricha anogona kushandiswa kuyera tembiricha, senge PT100, AD590, nezvimwe.
