The ERUN portable turbidity meter is CE, RoHS, and ISO 9001 certified, delivering lab-grade accuracy in a rugged handheld design for wastewater, drinking water, and industrial field testing.
Global water quality monitoring is expanding rapidly. The portable turbidimeter market alone was valued at USD 169 million in 2024 and is projected to reach USD 211 million by 2031 at a CAGR of 3.3%. Water treatment facilities, environmental agencies, and industrial plants worldwide require reliable, certified instruments for on-site turbidity measurement. This article explains why the ERUN portable turbidity meter meets the most stringent international standards and how it delivers dependable results in the field.
1. Overview & Working Principle
A portable turbidity meter is a handheld instrument that measures water clarity by detecting light scattered by suspended particles, with results expressed in Nephelometric Turbidity Units (NTU).
The ERUN-SP5-B6 portable turbidity meter adopts imported high-brightness long-life light source and cold light source narrow-band interferometric optical system, applying standard 90° infrared scattered light detection technology to eliminate water sample color interference thoroughly. The instrument fully complies with ISO 7027 international turbidity measurement standard and EPA 180.1 method, supporting dual-standard switching to meet diversified global regulatory testing requirements. When infrared light penetrates the water sample, suspended particles scatter the light, and the sensor accurately captures scattered light intensity — the data is positively correlated with water turbidity to realize precise quantitative detection.
Compact and lightweight, this intelligent water quality analyzer is specially designed for on-site rapid detection, with excellent test repeatability and stability.
2. International Authoritative Certifications
The ERUN portable turbidity meter is fully certified with CE, RoHS, and ISO 9001 – the three core credentials for international water quality equipment procurement and project bidding.
CE Certification: Complies with EU safety, health and environmental protection directives, meeting the mandatory access standards for European Economic Area market.
RoHS Compliance: Zero hazardous substances such as lead and mercury, environmentally friendly and pollution-free, suitable for ecological environmental monitoring scenarios.
