Description
Product Overview
The EISCO Turbidity Tube with Secchi Disk is engineered for professionals who need a dependable, easy-to-use instrument for assessing water transparency across a wide range of environments. Constructed from high‑impact, shatter‑resistant plastic, the tube withstands the rigors of fieldwork while maintaining optical clarity for accurate readings. A heavy rubber stopper provides a secure seal, preventing leaks and ensuring the sample remains undisturbed during measurement. The integrated Secchi Disk pattern is printed directly on the tube, eliminating the need for separate accessories and simplifying the testing process.
Measuring up to 120 centimeters, the scale is clearly marked on the exterior of the tube, allowing users to record the depth at which the Secchi Disk pattern becomes visible with precision. This length is sufficient for most freshwater and marine applications, from small ponds to larger lake and coastal assessments. The tube dimensions of 2 × 2 × 51 inches and a weight of 1.7 pounds make it portable yet robust, fitting comfortably in a field kit or laboratory bench.
Included with the product is a comprehensive instruction manual that covers the scientific background of turbidity measurement, step‑by‑step usage instructions, and troubleshooting tips. The manual also provides guidance on interpreting results in the context of water quality standards, helping users translate raw measurements into actionable insights. Whether you are a researcher, environmental consultant, or laboratory technician, the EISCO Turbidity Tube delivers the accuracy and durability required for high‑quality data collection.

Usage
The Turbidity Tube is designed for versatility. In field settings, simply fill the tube with a water sample, secure the stopper, and gently drain until the Secchi Disk pattern just disappears from view. Record the height on the 120 cm scale where the pattern becomes visible again as you raise the water level. This method works equally well in ponds, lakes, streams, groundwater wells, and even coastal ocean sites, making it a universal tool for water quality monitoring.
In laboratory environments, the tube can be used alongside other analytical equipment to cross‑validate turbidity readings or to provide a quick visual check before more detailed spectrophotometric analysis. Its shatter‑resistant construction allows repeated use without degradation, and the clear plastic body ensures that even low‑turbidity samples can be evaluated accurately. The tube’s simple design also makes it an excellent teaching aid for students learning about optical measurement techniques and environmental science.
Because the instrument does not rely on electronic components, it operates without batteries or power sources, reducing maintenance costs and eliminating the risk of electrical failure in remote locations. The lightweight design enables transport in backpacks, vehicle trunks, or boat compartments, ensuring that professionals can carry the tool to any site where water clarity assessment is needed.

FAQ
How do I interpret the depth reading on the 120 cm scale?
The depth reading indicates the point at which the Secchi Disk pattern becomes visible as you raise the water level. A deeper reading (higher centimeter value) corresponds to clearer water, while a shallower reading suggests higher turbidity. Compare your measurement against local water quality guidelines to determine if the water meets clarity standards.
Can the tube be used for both freshwater and seawater samples?
Yes. The tube’s material is chemically inert and resistant to saltwater corrosion, making it suitable for both freshwater bodies such as lakes and streams, as well as marine environments like coastal bays and offshore sites. Ensure the sample is well mixed before testing to obtain an accurate representation of turbidity.
What maintenance is required to keep the tube accurate?
After each use, rinse the tube thoroughly with clean water to remove any residual particles. Inspect the interior for scratches or clouding, which could affect optical clarity. The rubber stopper should be checked for wear and replaced if it no longer forms a tight seal. No additional calibration is required for routine measurements.
Is the Turbidity Tube compatible with other EISCO measurement devices?
The tube can be used alongside other EISCO instruments, such as handheld turbidity meters or spectrophotometers, to provide a quick visual reference. While the tube itself does not generate digital data, its readings can be recorded manually and entered into data logging software for comprehensive analysis.
What is the warranty period for this product?
EISCO offers a one‑year limited warranty covering manufacturing defects and material failures. If any issue arises within this period, contact EISCO customer service for a replacement or repair. Proof of purchase and serial number information will be required to process the warranty claim.
