Multiple kuyerwa nzira
PR291 yakatevedzana microhm thermometers uye PR293 akatevedzana nanovolt microhm thermometers akakwira-chaiyo yekuyera zviridzwa zvakagadzirirwa tembiricha metrology.Iwo akakodzera kune akawanda mashandiro, seyeyero yetembiricha data yetembiricha sensor kana data yemagetsi, tembiricha yekufanana bvunzo yecalibration mavira kana yekugezera, uye tembiricha yekuwana chiratidzo uye kurekodha kwematanho akawanda.
Nekuyerwa kwechiyero kuri nani kupfuura 7 1/2, zvichienzaniswa neyakajairwa yakakwira-chaiyo dhijitari multimeter, yakashandiswa zvakanyanya mukupisa metrology kwenguva yakareba, kune akawanda akagadziridzwa magadzirirwo maererano nemhando, basa, huchokwadi, uye nyore kushandisa kuita kuti tembiricha calibration process ive yakarurama, yakanakira uye nekukurumidza.
Features
- Chiyero chekunzwa kwe10nV / 10μΩ
Iyo yekubudirira dhizaini yeakanyanya-yakaderera ruzha amplifier uye yakaderera ripple magetsi ekupa module inoderedza zvakanyanya ruzha rwekuverenga rwechiratidzo loop, nekudaro ichiwedzera kunzwa kwekuverenga kune 10nV/10uΩ, uye nekuwedzera zvinobudirira madhijitari ekuratidzira panguva yekuyera tembiricha.
- Excellent kugadzikana kwegore
PR291/PR293 akatevedzana ma thermometers, achitora reshiyo yekuyera musimboti uye ane yakavakirwa-mureferensi-level standard resistors, ane yakanyanya kuderera tembiricha coefficient uye yakanakisa kugadzikana kwegore.Pasina kutora inogara tembiricha referensi basa, kugadzikana kwepagore kweiyo yese nhevedzano inogona kuramba iri nani zvakanyanya kupfuura inowanzoshandiswa 7 1/2 dijitari multimeter.
- Yakabatanidzwa yakawanda-channel yakaderera-ruzha scanner
Pamusoro peiyo chiteshi chemberi, kune maviri kana mashanu akazvimirira seti yeakazara-inoshanda bvunzo terminals akabatanidzwa pane yekumashure panhivi zvinoenderana nemhando dzakasiyana muPR291/PR293 akatevedzana mathermometers.Imwe neimwe chiteshi inogona yakazvimiririra kuseta yechiratidzo chechiratidzo mhando, uye ine yakanyanya kuenderana pakati pezviteshi, saka akawanda-channel data kutora kunogona kuitwa pasina chero ekunze switch.Mukuwedzera, iyo yakaderera-ruzha dhizaini inovimbisa kuti masaini akabatana kuburikidza nematanho haaunze yakawedzera ruzha rwekuverenga.
- High-chaiyo CJ muripo
Kugadzikana uye kurongeka kweiyo tembiricha yeCJ inoita basa rakakosha pakuyera kwepamusoro-chaiyo thermocouples.Inowanzo shandiswa yakakwirira-chaiyo dhijitari mita inoda kusanganiswa neyakakosha CJ muripo wemidziyo yekuyera thermocouple.Iyo yakatsaurirwa Yepamusoro-chaiyo CJ muripo module inosanganiswa muPR293 yakatevedzana thermometers, saka iyo CJ kukanganisa kweiyo yakashandiswa chiteshi zviri nani kupfuura 0.15 ℃ pasina mamwe maperipheral anogona kuitika.
- Yakapfuma tembiricha metrology mabasa
PR291/PR293 akatevedzana ma thermometers akakosha bvunzo chiridzwa chakagadzirirwa tembiricha metrology indasitiri.Kune matatu nzira dzekushandisa dzekutora, imwe-chani yekutevera, uye tembiricha mutsauko kuyerwa, pakati peiyo tembiricha mutsauko wekuyera modhi inogona kuongorora tembiricha yakafanana yemarudzi ese ezvinogara tembiricha michina.
Kana ichienzaniswa neyechinyakare dhijitari multimeter, 30mV renji yakanangana yekuyera S-mhando thermocouples uye 400Ω renji yePT100 platinamu kuramba kuyerwa inowedzerwa.Uye neakavakirwa-mukati ekushandura zvirongwa zveakasiyana tembiricha sensors, akasiyana masensor (seakajairwa thermocouples, akajairwa platinamu resistance thermometers, maindasitiri eplatinamu resistance thermometers uye anoshanda thermocouples) anogona kutsigirwa, uye dhata retifiketi kana dhata rekururamisa rinogona kurehwa kutsvaga. kudziya kwemhedzisiro yebvunzo.
- Data analysis function
Pamusoro peakasiyana bvunzo data, macurves uye kuchengetwa kwedata kunogona kuratidzwa, chaiyo-nguva data yakakura / shoma / avhareji kukosha, dzakasiyana siyana tembiricha kudzikama data inogona kuverengerwa, uye iyo yakanyanya uye shoma data inogona kumakwa kufambisa intuitive data kuongororwa. panzvimbo yekuedza.
- Portable design
High-chaiyo digitaalinen metres anowanzo shandiswa mumarabhoritari kazhinji akakura uye haatakurika.Kusiyana neizvi, PR291/PR293 akatevedzana ma thermometers idiki muhukuru uye huremu, inova yakanakira yemhando yepamusoro tembiricha yekuyedza munzvimbo dzakasiyana dzesaiti.Mukuwedzera, dhizaini yakavakirwa-mukati-yakakura-inokwana lithium bhatiri inoitawo kuti mashandiro ekushanda ave nyore.
