Comparative Analysis of Field Application Scenarios Between YUNTANG YT‑SXT1 and YT‑NTU Portable Turbidimeters

Portable turbidity meters have become mainstream devices for water‑quality field detection. Different models differ in measuring range, precision, storage capacity and peripheral functions, so users need to select equipment according to actual business scenarios. This article compares the hardware parameters, functional characteristics and applicable objects of two YUNTANG portable turbidity instruments: YT‑SXT1 and YT‑NTU.

YT‑SXT1 adopts 860 nm scattering method which complies with HJ1075‑2019 national environmental standard. Its measuring range reaches 0‑2000 NTU, resolution 0.001 NTU, with IP65 high‑level waterproof protection grade, 16 GB memory, supporting multi‑unit output and Bluetooth on‑site printing. It is more oriented to professional environmental monitoring, emergency water pollution disposal and high‑precision field sampling work for third‑party testing agencies. While YT‑NTU focuses on cost‑effective rapid detection. Its measuring range is 0.5‑300 NTU, equipped with cloud‑platform wireless transmission and sample‑dilution automatic conversion function. It is more suitable for enterprise internal routine patrol, factory water‑quality spot‑check, aquaculture and on‑site quick screening.

In the comparative field test, we collected water samples of high, medium and low turbidity levels. YT‑SXT1 shows better performance for high‑turbidity sediment‑containing river water. YT‑NTU is more light‑weight and easy‑to‑operate for repeated daily spot‑check tasks. Both instruments support Android system, Bluetooth and Wi‑Fi data transmission, lithium‑battery power supply for outdoor work. Laboratories and enterprises should select corresponding models based on measurement upper‑limit requirement, precision level, whether they need on‑site printing or cloud data management. This comparison provides practical reference for instrument procurement of water‑quality monitoring departments.
