Turbidity Meter – Portable Turbidity & TSS Analyzer for Field Precision
The Instrava Turbidity Meter is a portable, dual-detection analyzer engineered for accurate measurement of turbidity (NTU) and total suspended solids (TSS mg/L) in field and laboratory environments.
By combining the scattered light method (90° detector) and the transmitted light method (180° detector), and utilizing a near-infrared light source, the instrument effectively eliminates chromaticity interference and improves measurement stability in colored water samples.
The analyzer calculates turbidity and suspended solids concentration by measuring the ratio between scattered and transmitted light intensity, ensuring high accuracy and repeatability across low and high turbidity ranges.
Designed for decision-making. Built for field reliability.

Instrava OEM/ODM
Reliable Instruments. Solutions That Fit Your Application.
Instrava is focused on delivering reliable industrial solutions through carefully curated products, application-driven optimization, and flexible customization. We select proven instruments from trusted manufacturers to ensure consistent quality, optimize solutions based on real working conditions to solve practical challenges, and provide tailored configurations to meet specific application needs.
By combining selection expertise with application understanding, Instrava helps customers reduce risk, improve efficiency, and achieve dependable results in complex industrial environments.
How does the dual-detector system improve measurement reliability compared to single-beam turbidity meters?
Instrava’s turbidity meter integrates both 90° scattered light detection and 180° transmitted light detection. By calculating the ratio between the two signals, the instrument compensates for color interference and light attenuation, delivering more stable and repeatable readings — particularly in complex or colored wastewater samples. This directly reduces compliance risk and re-testing costs.
Is this meter suitable for both low-range drinking water monitoring and high-range wastewater applications?
Yes. The analyzer covers 0–20 NTU (high-precision low range) and 0–1000 NTU (wide industrial range), as well as 0–1000 mg/L TSS. This dual-range capability allows procurement teams to standardize one device across multiple departments, reducing inventory complexity.
How stable is the instrument during extended field inspections?
The meter maintains ≤±0.3% FS zero drift over 30 minutes and offers high repeatability (≤±0.05 NTU in low range). Combined with IP65 protection and battery operation, it ensures stable performance during long inspection cycles in municipal or industrial sites.
What calibration flexibility does the instrument provide for regulated environments?
Up to 4-point calibration (0–20 NTU)
Up to 7-point calibration (0–1000 NTU)
1-point TSS calibration
This allows engineers to align measurements precisely with site-specific standards, improving audit readiness and regulatory confidence.
Can this instrument reduce overall operational cost for water treatment plants?
Absolutely. By combining turbidity and TSS measurement in one portable device, operators eliminate the need for separate instruments. The high repeatability reduces retesting frequency, and the durable IP65 design minimizes maintenance and replacement costs.
What makes this turbidity meter a low-risk procurement choice?
Wide measurement coverage
Industrial-grade IP65 protection
Proven optical ratio measurement principle
Compact 290g field-ready design
Flexible battery options
For procurement managers, this means broad application coverage, lower equipment redundancy, and long-term usability across departments.
