Handheld Turbidity Meter

I. Product Overview

Turbidity is a key water quality indicator of the suspended particulate content of water and directly affects its sensory properties and safety. The instrument uses single-wavelength 860 nm scattered-light measurement, which effectively avoids interference from water colour and ensures accurate, reliable results. Precision optics and smart technology are combined in a compact, portable body with one-key calibration, fast response, a large display, data storage and a high protection class.

II. Measuring Principle

The scattered-light method uses a stable light beam passing through a sample cell containing the sample, with the sensor positioned perpendicular to the emitted beam to measure the intensity of scattered light. Within a certain concentration range, the intensity of the scattered light is proportional to the turbidity of the sample.

III. Applications

Environmental monitoring of rivers, lakes and groundwater; routine inspection of waterworks treatment trains from raw water to filtered water and of distribution network water; turbidity monitoring of influent, effluent and process stages in wastewater treatment; aquaculture water management; and monitoring of process and cleaning water in the food and beverage and pharmaceutical industries.

IV. Key Features

1. Android operating system with an elegant interface and user-friendly operation.

2. 4.3-inch high-definition touch screen combined with a visual graphical interface that greatly improves operating efficiency.

3. High-reliability imported LED light source: no warm-up required and stable long-term performance.

4. 10 mm × 10 mm large-area photocell for high sensitivity and a low detection limit.

5. 16 GB internal memory stores more than 10,000 records; an optional Bluetooth printer prints results on site.

6. Wi-Fi and Bluetooth connectivity plus a USB port for fast batch upload of data to a PC.

7. Water-resistant housing; the measuring chamber resists the ingress of 0.5 mL of liquid.

8. Standard USB-C 5 V 2.1 A input with BC 2.1 charging protocol support: compatible with third-party phone chargers, cables and power banks, with intelligent lithium-battery charge management for continuous mains operation.

9. Average measurement with automatic range switching.

10. The default display unit is NTU; other units such as FAU, FNU, FTU, EBC, ASBC and mg/L can be switched by the user.

11. Continuous multi-point turbidity calibration, zero-point calibration and built-in standards are supported.

12. Bilingual Chinese / English operating system.
