## Overview

The 7.87 Inch Plastic Secchi Disk Set is a professional-grade water clarity measurement tool featuring a durable acrylic disc with black and white quadrants, a rust-resistant stainless steel cone, a robust polymer holding line, and a 30-meter tape measure. Designed for both freshwater and seawater applications, this comprehensive kit offers precise, reliable transparency readings for hydrologists, marine biologists, and environmental scientists. Lightweight yet sturdy, it ensures easy transport and long-term use, making it an essential instrument for environmental monitoring and aquatic research.

## Description

Features: Prior to heading out to sea, it's important to check the robustness of the string that holds the Secchi disk. It should be pre-shrunken by soaking it in water, then tightened and dried. Regular checks and corrections should be applied during use. The set is easy to maintain. After each observation, simply wash the disk with fresh water and soak the rope in fresh water before drying and storing it. Ensure the plate is always kept clean. If the paint falls off or gets dirty, it should be repainted. This set is a practical tool for water clarity tests. With the Secchi disk set, you can measure the transparency of both fresh and salt water. It is ideal for hydrologists, marine biologists, environmental scientists, and water enthusiasts alike, and can be applied for hydrological research, environmental observation, aquatic farming, and other fields. Specifications: Material: Disc material: acrylicCone material: stainless steelString material: polymerColor: Disc color: As picture shownSize: Disc size: about 7.87 inches/ 20 cm in diameterTape measure size: about 30 meter measurementRope length: about 16.4 ft/ 5 meterPackage includes: 1 x Secchi disk1 x Roll holding string1 x Cone weight1 x Tape measureNotes: Manual measurement, please allow slight errors in size. The color may exist a slight difference due to different screen displays. Winding risk may exist, keep away from kids under 3 years old. Attach the string or tape measure to the disc for measuring. A clip is equipped for attaching the tape measure. The observation of seawater transparency is only carried out in daytime, and the observation place should be in the back of the sun, and the influence of sewage discharged from the ship should be avoided during observation.

Review: Bought this as a gift for my husband and he said he worked great!
Review: Good quality but the tape does not start at zero - there is an additional 16 cm of tape which creates a measurement error.

## Features

- Comprehensive Package: Each set includes all the necessary items for water clarity measurements. The package contains 1 Secchi disk, 1 roll of holding string, 1 cone weight, and 1 tape measure. This ensures you have the essential tools for accurately measuring water transparency in both fresh and seawater.
- Ideal Size: The Secchi disc, with a diameter of approximately 7.87 inches (20 cm), is well-sized for efficient visibility underwater. The tape measure features a length of about 30 meters(only meter measurement), and the rope is approximately 16.4 ft (5 meters) long. These measurements provide ample depth tolerance for deep water clarity measurement without hindrance.
- Quality Materials: The acrylic Secchi disc, a crucial component, is made from acrylic, ensuring resilience, lightweight portability, and durability. The cone, designed to weigh down the disc, is crafted from stainless steel for longevity and resistance to rust. The holding string is made from robust polymer, capable of handling the disc and cone weight without elasticity, making it sturdy for long-term use.
- Freshwater Measuring: Use the black and white side of the disc. On an unclouded day with stable water surface, lower the acrylic Secchi disc into the water with a holding rope until it is hardly visible from above. Measure the length of the rope immersed in water, repeat several times, and calculate the average for freshwater clarity.
- Saltwater Measuring: Use the pure white side of the disc. At the backlight of the main deck, put the plastic Secchi disc into the water, sinking to a depth just out of sight. Slowly lift the rope until the disc is faintly visible. Read the mark of the rope on the water surface, repeat 2 or 3 times, and calculate the average for observed clarity. In wavy conditions, correct the depth if the inclination angle exceeds 15 degrees, and read the marks at the crest and trough respectively.
- Notice: The Tape Measure is only meter measurement. Please confirm it is suitable for you before buying.
