HYDRO BIOS PRS Precise Rosette System

HYDRO BIOS PRS Precise Rosette System PRS Precise Rosette System Water Sampling + Measuring System In cooperation HYDRO-BIOS and Sea & Sun Technology have developed the Precise Rosette System PRS - a sturdy array fabricated of stainless steel and equipped with Quick Change Racks for simple mounting of watersamplers in 6-12-24-bottles arrays combined with a CTD-Multiparameter Probe for autonomous, reliable and high accuracy operation. The approved Precise Rosette System PRS is an instrument designed for the collection of water samples in successive water layers - triggered by the CTD 90 Probe. The maximum operational water depth is 2000 metres. A special version for operational depths down to 6000 metres is available upon request. The state-of-the-art electronics, optimized in power consumption, are designed for ambient temperatures from -10° C up to + 50° C. For detailed information download the PRS data sheet PRS 12 Sampling The sturdy array fabricated of stainless steel is equipped with twelve racks to which Plastic Water Samplers and Free Flow Samplers with capacities from 1.7 to 10 litres can be mounted to collect water samples in twelve different depth steps during one operation. The Precise Rosette System PRS 12 is equipped with a motor-driven release device with an integrated Depth Meter ( measuring range according to customer ´ s requirements) - the water samplers are closed in the succession of their mounting to the array ( i.e. No. 1, 2, 3, ... 10, 11 and 12) . The water samplers are actuated via push-button control by a Personal Computer using SDA software. Measuring The CTD 90 is a lightweight high precision measuring system for measurements of physical, chemical and optical parameters. It is designed for precise insitu acquisition of scientific data in oceanic, estuarine, limnic and freshwater environments up to 2.000 metres water depth ( 6.000 metres on request) . The CTD90 allows the simultaneous measurement of following parameters: pressure ( depth) , temperature, conductivity, pH, Redox ( ORP) , dissolved oxygen, H2S, light transmission, light scattering ( 90° ) , current meter with compass, chlorophyll a ( green algae) , blue algae. Main features: low weight easy handling max. 9 sensors plus 3 external titanium housing depth range up to 2000 m 6000 m on request triggering HYDRO-BIOS rosette sampling systems Windows® 98/ Me/ 2000/ XP based standard data acquisition software SDA software PRS 12 No. 439 512 PRS 24 No. 439 524
