Turbidity Tube with Secchi Disk 60cm Scale – Eisco Labs Instrument

Description

Product Overview

The Turbidity Tube with Secchi Disk from Eisco Labs is engineered for precise water clarity measurement across a broad range of environmental settings. Constructed from high‑impact, shatter‑resistant plastic, the tube withstands the rigors of field work while maintaining optical clarity for accurate readings. A 60cm graduated scale is printed directly on the tube’s exterior, allowing users to quickly gauge the depth at which the Secchi disc pattern becomes visible. The heavy rubber stopper provides a secure seal, preventing sample leakage and ensuring consistent measurement conditions. A flexible drainage hose attached to the bottom of the tube facilitates rapid emptying and refilling, streamlining the testing process. The package includes a comprehensive instruction manual that covers the scientific background of turbidity measurement, step‑by‑step usage instructions, and troubleshooting tips, making it suitable for both seasoned researchers and newcomers to water quality analysis.

Usage

This turbidity tube is designed for a variety of aquatic environments, including freshwater ponds, lakes, streams, groundwater wells, and marine settings such as coastal bays and offshore monitoring stations. Field technicians can submerge the tube in a water sample, allow the Secchi disc to settle, and then read the depth at which the disc pattern first becomes discernible. The 60cm scale provides a wide measurement range, accommodating both low‑turbidity clear waters and highly turbid conditions. The instrument is lightweight (approximately 14.4 ounces) and compact (24.3 x 2 x 2 inches), making it easy to transport in a field kit or laboratory backpack. Its durable construction ensures reliable performance even when exposed to temperature fluctuations, UV radiation, and occasional impacts.

FAQ

How do I read the turbidity measurement using the Secchi disc?

Fill the tube with the water sample, then gently lower the Secchi disc into the water. Observe the depth at which the disc pattern first becomes visible against the background. Record the corresponding value on the 60cm scale; this depth correlates directly with the turbidity level of the sample.

Can the tube be used for both freshwater and seawater samples?

Yes, the tube is designed to handle a wide range of salinities. The plastic material is chemically inert and does not react with salts, making it suitable for testing in freshwater lakes, rivers, groundwater, as well as marine environments such as coastal bays and offshore sites.

What maintenance is required to keep the tube accurate?

After each use, rinse the tube with clean water to remove any residual particles. Inspect the rubber stopper and drainage hose for signs of wear or damage, and replace them if necessary. Periodically verify the scale accuracy using a calibrated reference solution provided by Eisco Labs or an accredited laboratory.

Is calibration needed before each measurement session?

While the tube is pre‑calibrated at the factory, it is good practice to perform a quick verification with a known standard solution at the start of each field session. This ensures that any minor variations due to temperature or handling are accounted for, delivering the most reliable data possible.

What warranty and support does Eisco Labs provide?

Eisco Labs offers a one‑year limited warranty covering manufacturing defects. Customers can contact the technical support team via email or phone for assistance with operation, troubleshooting, or ordering replacement parts. Detailed warranty terms are included in the product documentation.
