Portable Turbidity Meter LTM-A19 Catalog
Labtron Turbidity Meter provide measurement of cloudiness or haziness of fluid caused by presence of suspended particles. They consist of light source including laser, for measuring turbidity levels accurately. Their photodetector captures scattered light, converting it into measurable electrical signals for analysis. They feature sample chamber where water samples are placed for turbidity testing. Our Turbidity Meter evaluates water clarity in wastewater treatment, aquaculture, storm water management, recreational water testing.








A portable turbidity meter is a handheld device used to measure the clarity or cloudiness of a liquid, typically water. It works using a light-based method—usually by shining a beam of light through the sample and measuring how much light is scattered at a 90° angle by particles suspended in the liquid. The more particles there are, the cloudier the water, and the higher the turbidity reading. These readings are usually given in NTU (Nephelometric Turbidity Units). Portable models are ideal for use in the field or lab due to their small size and battery-powered operation.
Portable turbidity meters are used across a wide range of industries and testing environments. They are commonly used in water treatment plants, power stations, and sewage facilities to monitor water quality. The beverage and wine industries use them to check the clarity of products. Environmental agencies and laboratories use them to test river and lake water for pollution. They are also useful in pharmaceutical manufacturing and industrial water testing where precision and quick field testing are required.
Labtron's portable turbidity meters are designed with high-precision optical systems and stable electronic circuits to ensure accurate readings. They offer repeatable results with low error margins and minimal drift over time. These meters are built to perform consistently even with power fluctuations and under various environmental conditions. The device’s accuracy, combined with reliable performance, makes it a trusted tool for professionals who need dependable turbidity data.
Labtron’s portable turbidity meters are designed with ease of use in mind. They feature a compact and lightweight build for easy transportation and operation. The devices include a large, clear LCD screen that displays readings even under bright light conditions, which is helpful during outdoor testing. They can operate on both battery and AC power, and offer features like low battery alerts and data output options, making them ideal for long-term field work or lab use.
To keep a Labtron portable turbidity meter in good working condition, regular calibration using standard solutions is recommended to maintain accuracy. After each use, the sample cell should be cleaned thoroughly to avoid contamination or residue build-up. The device should be stored in a clean, dry place, ideally at temperatures between -20? and 55? and with humidity below 80%. Always remove batteries if the device won't be used for an extended period to prevent leakage and circuit damage.
