Turbidity Meter
In water quality testing, accuracy and durability are everything — especially when you’re out in the field. The HORIBA LAQUA TB220 Portable Turbidity Meter is built to deliver both, combining laboratory-grade precision with a rugged design ready for any environment. Whether you’re monitoring drinking water, wastewater, or environmental samples, the TB220 ensures your turbidity readings remain dependable, repeatable, and compliant with international standards.
Designed for the Realities of Fieldwork
The LAQUA TB220 isn’t just another handheld meter. It’s built to handle the demanding conditions faced by environmental scientists, technicians, and water authorities every day. The casing is shockproof, scratch-resistant, and non-slip, designed to stand up to knocks, dust, and moisture. Rated IP67 waterproof and dustproof. This instrument is safe to use even in wet field conditions (excluding the vial mounting area).
Its large, backlit LCD display (50 x 40 mm) ensures visibility even under bright sunlight or low-light environments. The intuitive interface, complete with a smiley face stability indicator, makes it clear when readings have stabilised, helping to eliminate user error and boost confidence in every result.
How It Works: Ratiometric Turbidity Measurement
At the heart of the TB220’s precision lies its ratiometric turbidity measurement principle. This method uses both nephelometric light scatter and transmitted light signals to ensure highly accurate readings across the full range of 0.00 to 2000 NTU.
This dual detection system minimises the effects of colour and stray light — factors that can easily skew results in single-beam instruments. The infrared light source (860 nm) and silicone photodiode detector ensure consistent performance, even with coloured or complex water samples.
The meter meets ISO 7027 and DIN EN 27027 standards, ensuring full compliance with international turbidity measurement protocols. That makes it ideal for regulatory reporting, especially for organisations required to monitor and submit raw water quality data.
Calibration Made Easy with SDVB Polymer Standards
Accurate calibration is key to reliable turbidity data. The LAQUA TB220 simplifies this process with up to four selectable calibration points using Styrene Divinylbenzene (SDVB) polymer standards — supplied in 0.02, 20, 100, and 800 NTU concentrations.
These polymer-based standards are long-lasting and stable, providing greater accuracy and less maintenance than traditional formazin solutions. The included calibration kit, along with sample vials, silicone oil, and cleaning cloth, ensures you have everything you need to keep your measurements consistent from day one.
Data Handling and Connectivity
Modern water testing requires more than just good readings — it requires good data management. The TB220 can store up to 2000 readings, each with a date and time stamp thanks to its real-time clock.
Results can be easily transferred to a computer using the PC (USB) cable. Additionally, they can be printed directly via a printer (RS232) connection. The meter’s firmware is software-upgradeable, ensuring it stays compatible with future updates and laboratory data systems.
Whether you’re building long-term turbidity records or auditing field performance, the TB220 offers a reliable way to track and manage results efficiently.
Built for Practicality and Longevity
The LAQUA TB220 runs on four AA batteries, capable of delivering around 2000 measurements before replacement. Its auto shut-off function (adjustable between 1–30 minutes or disabled entirely) helps conserve battery life when working in the field.
Compact yet solid, the instrument weighs approximately 510 grams with batteries. It measures 210 x 110 x 55 mm. Easy to handle, yet sturdy enough to feel substantial in use. The included durable carrying case keeps everything organised and protected, making it ideal for technicians who move between sampling sites.
Accuracy You Can Rely On
The TB220’s performance speaks for itself:
-
Range: 0.00 to 2000 NTU
-
Accuracy: ±0.02 NTU or ±2% (0–1000 NTU), ±3% (1001–2000 NTU)
-
Repeatability: ±0.02 NTU or ±2%
-
Sample volume: just 10 mL
Such precision and repeatability make it a trusted choice for applications across drinking water, environmental monitoring, wastewater treatment, and industrial process control.
HORIBA’s LAQUA series is known globally for dependable, field-ready water quality instrumentation. The TB220 continues that tradition with a three-year meter warranty, ensuring long-term value and peace of mind.
For laboratories, councils, and environmental professionals looking for a turbidity meter that balances precision, compliance, and usability, the LAQUA TB220 stands out as a robust and intelligent solution — ready to deliver accurate data, wherever your work takes you.
