DO Meter atau Dissolve Oxygen Meter adalah ?

Oksigen AirDalam Penjualan Alat ukur kami tentunya harus mengetahui apa itu DO Meter ? bagaimana cara penggunaanya ? dan bermanfaat untuk apa ? dalam hal ini kami CV Java Multi Mandiri menyediakan instruments untuk penjualan DO Meter adapun kami ulas kembali Definisi Oksigen.

Oksigen merupakan unsur gas dengan symbol O. Gas ini tidak berwarna dan tidak mempunyai rasa. Di dalam tubuh, oksigen diedarkan ke seluruh tubuh oleh darah. Oksigen diperlukan oleh sel untuk mengubah glukosa menjadi energi. Selanjutnya energi inilah yang digunakan untuk melakukan berbagai aktivitas seperti aktifitas fisik, penyerapan makanan, membangun kekebalan tubuh, pemulihan kondisi tubuh dan penghancuran bebarapa racun sisa metabolisme.Kekurangan oksigen menyebabkan metabolisme tidak berlangsung sempurna. Akibatnya tubuh terasa lelah, pegal-pegal, mengantuk, kekabalan tubuh menurun sehingga mudah terserang penyakit.

DO Meter atau Dissolve Oxygen Meter adalah ?

Oksigen dapat larut dalam air. Molekul-molekul oksigen menempati ruang di antara molekul air. Kandungan oksigen di dalam air dipengaruhi berbagai faktor seperti suhu, tekanan dan jumlah zat yang terlarut di dalam air. Semakin rendah suhu air, kandungan oksigen yang terkandung semakin besar. Itulah sebabnya kita merasa lebih segar jika minum air dingin, Tekanan yang besar dapat memaksa lebih banyak molekul oksigen masuk ke dalam ruang di antara molekul air, Kemurnian air juga mempengaruhi kelarutan oksigen. Air yang murni memungkinkan oksigen terlarut lebih banyak.

Alat yang digunakan untuk menganalisa kadar oksigen terlarut adalah DO meter.  Cara penggunaan alat ini adalah dengan mencelupkan alat DO meter tersebut kedalam sampel air laut dan melihat skala yang terlihat.

DO (Dissolved Oxygen)

DO atau kadar oksigen terlarut menyatakan kandungan oksigen di dalam air. Kemampuan air dalam melarutkan oksigen sangat tergantung pada suhu air, tekanan gas oksigen dan kemurnian air. Oksigen terlarut (dissolved oxygen, disingkat DO) atau sering juga disebut dengan kebutuhan oksigen (Oxygen demand) merupakan salah satu parameter penting dalam analisis kualitas air.

Nilai DO yang biasanya diukur dalam bentuk konsentrasi ini menunjukan jumlah oksigen (O2) yang tersedia dalam suatu badan air. Semakin besar nilai DO pada air, mengindikasikan air tersebut memiliki kualitas yang bagus. Sebaliknya jika nilai DO rendah, dapat diketahui bahwa air tersebut telah tercemar. Pengukuran DO juga bertujuan melihat sejauh mana badan air mampu menampung biota air seperti ikan dan mikroorganisme.

Selain itu kemampuan air untuk membersihkan pencemaran juga ditentukan oleh banyaknya oksigen dalam air. Oleh sebab pengukuran parameter ini sangat dianjurkan disamping paramater lain seperti kob dan kod. Di dalam air, oksigen memainkan peranan dalam menguraikan komponen-komponen kimia menjadi komponen yang lebih sederhana.

Oksigen memiliki kemampuan untuk beroksida dengan zat pencemar seperti komponen organik sehingga zat pencemar tersebut tidak membahayakan. Oksigen juga diperlukan oleh mikroorganisme, baik yang bersifat aerob serta anaerob, dalam proses metabolisme. Dengan adanya oksigen dalam air, mikroorganisme semakin giat dalam menguraikan kandungan dalam air.

Rangkumannya DO METER adalah alat untuk mengukur kadar oxygen dalam air. DO Meter adalah singkatan dari  “Dissolve Oxygen Meter” Nilai DO dalam air itu sangat tergantung pada jumlah zat organiK dalam air dan juga tergantung suhu air dimana semakin tinggi suhu air maka semakin rendah nilai DO nya.
