Laser range finders yog categorized thiab xaiv.
Laser rangefinders muaj xws li ultrasonic rangefinders, handheld laser rangefinders, thiab laser rangefinders (telescope laser rangefinders). Ib qho yog los txiav txim siab koj qhov kev ntsuas ntau; lwm qhov yog txiav txim siab qhov ntsuas qhov tseeb; qhov thib peb yog lub sijhawm siv. Thaum yuav khoom, koj yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:
1. Yog tias koj tsuas yog yuav tsum ntsuas qhov kev ncua deb li ntawm ob peb meters lossis ntau tshaj kaum meters, thiab qhov yuav tsum tau ua kom raug tsis yog siab heev: koj tuaj yeem xaiv "ultrasonic range finder". Txij li thaum ntsuas cov txiaj ntsig ntawm ultrasonic rangefinder cuam tshuam zoo heev los ntawm ib puag ncig, nws txoj kev ruaj ntseg thiab kev coj ua phem dua li cov laser rangefinder, tab sis nws cov nqi kuj pheej yig! Ntau haum rau kev ntsuas sab hauv tsev.
2. Qhov ntsuas qhov deb tsis ntev, thiab feem ntau yog siv sab hauv tsev. Thaum qhov tseeb qhov yuav tsum tau muaj siab: "handheld laser rangefinder" tuaj yeem xaiv. Hom rangefinder no yog qhov tsim nyog rau kev siv sab hauv tsev, thiab nws qhov ntsuas qhov tseeb thiab cov nyhuv zoo heev!
3. Kev ntsuas qhov ntev, feem ntau yog siv rau sab nraum zoov siv: "telescopic laser rangefinder" (ie: laser rangefinder telescope) tuaj yeem yuav. Nws yog ob qho tib si telescope thiab rangefinder; Nrog ntau qhov kev soj ntsuam zoo, tus neeg siv tau yooj yim taw ntawm lub hom phiaj rau kev ntsuas kev deb tsuas yog los ntawm kev pom qhov pom ntawm qhov muag hauv qhov muag. Nws emits thiab tau txais cov pob tshab infrared laser uas tsis muaj teeb meem rau lub qhov muag, tuaj yeem ntsuas qhov deb ntawm lub hom phiaj, thiab yog qhov me me, lub teeb thiab nqa tau yooj yim.
4. Kev ntsuas qhov ntev thiab kev ntsuas sab nraum zoov: Koj tuaj yeem xaiv lub teeb tsa hauv lub teeb pom kev zoo, kom koj tuaj yeem pom meej dua nyob rau hauv lub teeb muaj zog. Vim qhov yooj yim ntawm precision ntsuas.
Kev ceev faj thaum siv lub laser rangefinder: Lub laser rangefinder tsis tuaj yeem tsom rau tib neeg lub qhov muag rau kev ntsuas ncaj qha los tiv thaiv kev puas tsuaj rau tib neeg lub cev. Nyob rau tib lub sijhawm, qhov dav dav laser ntau yam finder tsis muaj dej tsis muaj dej, yog li nws yuav tsum tau them sai sai rau cov dej tsis zoo thaum siv lossis khaws cia.
Cov saum toj no yog qee cov lus qhia uas yuav tsum tau them sai sai rau thaum yuav khoom thiab siv laser rangefinders. Rau kev siv tshwj xeeb, xa mus rau cov lus qhia khoom thiab phau ntawv qhia.
