Portable Turbidity Meter LH-P305
It complies with the double-beam measurement method recommended by the standard "HJ 1075-2019 Determination of water turbidity - Turbidimeter method". Using the 90° scattered light method, with infrared LED and white LED, it can automatically switch between high and low ranges, and the light source has a lifespan of up to 100,000 hours.

Features
1) Comply with standards: Comply with the double-beam measurement recommended by "HJ 1075-2019 Water Quality - Determination of Turbidity - Turbidimeter Method";
2) Professional testing: widely used in scientific research institutions, water plant breeding, environmental monitoring, swimming pool testing, water plants and other fields;
3) Dual-beam measurement: Two low-range measurement modes of infrared white light are available. The former can provide effective chromaticity compensation, and the latter is more accurate;
4) Screen display: Using a 3.5-inch high-definition color screen, readings and operations are clearer;
5) Algorithm innovation: nonlinear data processing; using ratio readings to effectively avoid the influence of ambient temperature. Measurement data is stable and reliable;
6) Dual-mode value output is more professional: built-in regular mode and signal average mode, the reading method is more professional;
7) Using LED light source is more reliable: using high-intensity and long-life light source to minimize maintenance costs, the light source does not need to be warmed up for a long time before it can work normally;
8) Multi-point calibration: Multi-point calibration can be performed quickly, which is better suitable for various water sample concentrations and has wider applications.
