PR721/PR722 Series Precision Digital Thermometer
Hoʻohana ʻo PR721 series precision digital thermometer i ka sensor naʻauao me ka hoʻopaʻa ʻana i ka hale, hiki ke hoʻololi ʻia me nā mea ʻike o nā kikoʻī like ʻole e hoʻokō i nā pono ana wela.ʻO nā ʻano sensor i kākoʻo ʻia e pili ana i ke kūpaʻa platinum wire-wound, thin-film platinum resistance, thermocouple and humidity sensors, hiki ke hoʻomaopopo a hoʻouka i ke ʻano, ka pae wela a me ka waiwai hoʻoponopono o ka sensor pili.Hana ʻia ka thermometer me ka alumini alumini holoʻokoʻa, me ka papa pale IP64, hiki ke hoʻohana pono ʻia i nā wahi paʻakikī.
Nā hiʻohiʻona ʻenehana
- ʻIke akamai, uhi ka pae wela -200 ~ 1300 ℃.Ke hoʻohana nei i nā ʻāpana paʻa kiʻekiʻe wela, hiki i ka mea hoʻokipa ke hoʻouka i ke ʻano sensor o kēia manawa, ka pae wela a me ka waiwai hoʻoponopono ma hope o ka hoʻopili ʻana i ka sensor akamai, hoʻomaikaʻi i ka pololei o ka traceability wela, a me ka hana pono.
- ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa, ma ka laulā o 5 ~ 50 ℃, ʻoi aku ka maikaʻi o ke ana ʻana o ka uila ma mua o 0.01, a ʻo ka hoʻonā ʻana he 0.001 ℃, hiki ke hoʻokō i nā koi calibration kiʻekiʻe.
- Ma ke ʻano U disk, hiki ke hana ʻia ka hoʻouka ʻana a i ʻole ka lawe ʻana i ka ʻikepili ma o ka micro USB interface, kahi kūpono no ka hoʻoponopono wikiwiki ʻana i ka ʻikepili hoʻāʻo.
- Hiki ke loaʻa ka ʻike heluhelu maikaʻi ma ka waiho ʻana iā ia ma ka hema a ʻākau paha.
- Kākoʻo i ke kamaʻilio Bluetooth a i ʻole ZigBee, hiki iā ʻoe ke hoʻohana i ka Panran Smart Measurement APP e hoʻonohonoho i ka ʻikepili a hoʻonui i nā noi ʻē aʻe.
- ʻO ka papa palekana IP64 no ka hoʻohana pono ʻana i nā wahi paʻakikī.
- ʻO ka hoʻohana mana haʻahaʻa haʻahaʻa, kūkulu ʻia i loko o ka pā lithium rechargeable, hana mau no nā hola he 130.
