Secchi Disk with Lanyard - Water Quality Testing Features
-
EASY TO USE: Secchi Disk with Lanyard Includes everything you need to get started. It includes disk, cord, cord holder & instructions. The Secchi Disk is used to measure how deep a person can see into the water. This is a measurement of water clarity.
-
WATER TRANSPARENCY MEASUREMENTS: Test Assured Secchi Disc is a timeless tool for checking water transparency in any body of water. This clarity measurement is required by a majority of the states’ health boards. Close to 100ft of cord is included to ensure you have enough for any water testing situation.
-
Multipurpose Disk: Secchi Disk is used to determine the transparency of water in lakes, streams, oceans, and other bodies of water. It is an eight-inch diameter disk with alternate black and white quadrants. By placing the disk in water and holding onto the string a user can measure the clarity of water.
-
DETERMINE TURBIDITY OF WATER: This black and white disk is used to determine the turbidity of natural water. The disk is raised or lowered several times to determine the average depth at which it disappears from sight. It includes a sounding lead and line.
-
SUITABLE FOR VARIOUS DEPTH: The Secchi disk is designed for use in shallow water and works best in shaded areas to eliminate glare from the sun. A best practice is to use the average of two depth measurements. With 72 feet of cord, it is suitable for a variety of depths.
About Secchi Disk With Lanyard - Water Quality Testing
The Secchi disk has been a valuable tool since it was first created by Angelo Secchi back in 1865. Our Test Assured Secchi disk includes everything you need to get started and is one of the most high-quality discs on the market. SIMPLE & EFFECTIVE TOOL: Secchi disk is a simple and effective tool that allows you to determine the productivity of freshwater lakes. Constructed of sturdy white plastic, the disk alternates between white and black printed quadrants. Fused to the bottom of the disk is a weight to help it sink. Attached at the center of the top side is the 100-foot cord which includes a polymer foam bobbin for visibility. FEATURES: ● Weighted, black and white solid plastic Secchi disc ● 72’ rot-proof polymer cord ● Spool to wind excess cord ● Detailed instruction manual INDICATION OF TURBID WATER: Measurements are taken by lowering the Secchi disk until it can no longer be seen. This point is known as the Secchi depth. Because light can penetrate deeper in clear water, the further the disk sinks, the higher the Secchi depth, which indicates clearer waters. The presence of high concentrations of algae and particulate in the water decrease visibility, in turn, decreasing the Secchi depth measurement, indicating turbid water. BENEFITS: ● Indicate Clearer Water ● Test Various Kinds of Water ● Check the turbidity of water ● Designed for use in Shallow Water ● Perfect for Various Depth NUMEROUS READINGS FOR WATER: Lake transparency can change with the seasons due to temperature and the amount of exposure to sunlight. It is important to take numerous Secchi disk readings throughout the year. An increase in Secchi depth shows improvement in water quality, while a decrease shows that water quality is declining.
