Development of RHA deep portable water sampler

Development of RHA deep portable water sampler / Muhammad Alif Ariffin Jasmi_
Untuk mengambil air, kualiti dan kesihatan air perlu berada di peringkat tertinggi. Untuk melakukan kajian ke atas air, penyampel air boleh dipercayai yang tidak menjejaskan dan integriti sampel yang diambil supaya ia boleh digunakan untuk mewakili air yang dikaji. RHA Deep Portable Air Sampler adalah penyampel air yang berbentuk silinder dengan dimensi 250mm x 60 mm diameter. Untuk memastikan sampler ini dapat mencapai lebih daripada 30 meter yang merupakan had kedalaman produk sebelumnya, kaedah pam telah diperkenalkan dan penyampel ini dilengkapi dengan unit kawalan elektronik untuk meningkatkan ketepatan dalam mengukur kedalaman semasa proses pensampelan. Dengan konsep pam, penyampel ini boleh mencapai lebih daripada 30 meter dengan jumlah persampelan yang tidak terhad. Aliran air dikawal oleh pam melalui paip PVC fleksibel. Bahan-bahan yang telah digunakan untuk membangunkan penyampel ini dipastikan untuk menjadi sesuai untuk air dan tiada tindak balas fizikal dan kimia berlaku antara penyampel dan air diekstrak dengan itu tidak mengubah sifat air. Oleh itu, keaslian dan integriti air diekstrak telah pun dipastikan. Kedalaman maksimum penyampel telah disahkan dari kuasa pam dan penyampel boleh mencecah sehingga 58.9 meter. Dengan menggunakan daya keapungan dan konsep daya seretan, penyampel ini dipastikan stabil dan kekal pegun apabila ia tenggelam di dalam air. Oleh itu, penyampel air yang boleh dipercayai dimana boleh mengekalkan integriti dan keaslian air telah dibangunkan. _______________________________________________________________________________________________________ To consume water, the quality and health of water need to at highest level. To do the study on water, a reliable water sampler that does not affect and integrity of sample taken so that it can be used to represent the water studied. The RHA Deep Portable Water Sampler is a cylindrical water sampler with a dimension of 250mm x 60 mm diameter. To ensure this sampler able to reach more than 30 meter which is the depth limitation of the previous product, pump method has been introduced and this sampler is equipped with the electronic control unit to increase accuracy in measuring depth while sampling process. With the pump concept, this sampler can reach for more than 30 meter with unlimited sampling volume. The flow of the water is controlled by a pump through flexible PVC pipe. The materials that have been used to develop this sampler was ensured to be suitable for water and no reaction physically and chemically occurred between sampler and water extracted thus does not change the characteristic of water. Therefore, the originality and integrity of water extracted were ascertained. The maximum depth of the sampler has been verified from the pump power and the sampler can reach up to 58.9 m. By using buoyancy force and drag force concept, this sampler was ensured to be stable and stays stationary when it submerged in the water. Thus, reliable water sampler which can maintain the integrity and originality of water was developed.
