Product Review: EC-TN100-IR NTU Turbidimeter

The Instrument Choice Team of Scientists regularly reviews new and popular products, so when searching for the perfect scientific instrument for your application, you can make more informed decisions.

This edition assesses the EC-TN100-IR NTU Turbidimeter, a practical, popular and affordable turbidity meter suitable for an extensive range of water quality monitoring applications.

What is a Turbidimeter?

Turbidimeters (also “turbidity meters”) are water quality analysis tools that measure the “cloudiness” of water samples due to the presence of suspended particles. The higher the level of turbidity, the greater number of particles in the water sample.

NTU turbidimeters

NTU stands for Nephelometric Turbidity Unit, which is a standard and commonly used unit of turbidity measurement. (Note: NTU is equivalent to Formazine Turbidity Unit (FTU).) NTU instruments measure scattered light from a water sample at a 90-degree angle from the incident light.

This technology combines a light source, lens, sensor, processor and LCD screen to measure and display readings.  You place your sample between the light source and a sensor. Irrespective of the level of suspended particles present, the light will pass through your sample and arrive at the sensor at a 90° angle. Internal processors calculate the amount of light scattering and compare results against known standards on a calibration curve. Your resulting turbidity measurement will then appear on the LCD. This process may seem complex, but it all happens within a matter of seconds. 

Introducing the EC-TN100-IR NTU Turbidimeter

The EC-TN100-IR NTU Turbidimeter is a microprocessor-based, waterproof, fast, and accurate turbidity meter. This device is IP67 rated water and dustproof – and what’s more, it floats on water, which means it is superbly suited to the rigours of fieldwork.

The EC-TN100-IR comes as a kit with everything you’ll require for accurate turbidity measurements. The kit includes:

1. The EC-TN100-IR NTU Turbidimeter
2. A set of 4 calibration standards (800, 100, 20.0 & 0.02 NTU)
3. Seven sample vials
4. A lint-free cloth
5. Silicone oil
6. Batteries
7. Comprehensive instruction manual; and
8. Hard carrying case.

 The Impressive Features of the EC-TN100-IR NTU Turbidimeter

• Light Source: Infrared-emitting diode (850nm wavelength) offers a consistent light source and meets the criteria specified in ISO 7027 and DIN 27027 standards.
• Microprocessor-Based: The meter has an internal microprocessor that ensures quick measurements and unprecedented full-range accuracy.
• Water and Dustproof Housing: Your turbidity meter will excel in wet conditions due to ABS plastic casing that is easy to clean and maintain, an IP67 waterproof rating and the units' ability to float on water.
• Auto-Ranging: The meter automatically calculates and, within seconds, displays on its LCD a sample’s average turbidity level and range.
• Simple Calibration: Calibration is straightforward. Users need only insert a standard and press the “CAL” button. The device prompts users when the next calibration standard is required.
• LCD Screen: Results are easy to read on the extra-large LCD screen. The screen also displays units of measure and gives message codes to help simplify the meter’s operation.
• Advanced Power Management: Users can enjoy up to 1200 sample measurements on a single set of batteries.
• Auto-Off: The unit automatically switches off 20 minutes after the last button press to conserve battery life.
• All-in-One Kit: The EC-TN100-IR NTU Turbidimeter comes with all the tools required to start making fast, accurate and reliable turbidity measurements for almost any application.
