Models of Turbidity Meter

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.

Portable Turbidity Meter LTM-A15 FAQ's
  • Labtron Portable Turbidity Meter supports broad measuring range of 0 to 100 and 100 to1000 NTU, making it ideal for testing both clear and highly turbid water. This makes it particularly useful in industrial settings like wastewater treatment or during stormwater runoff analysis. Our meter's precise optical components and robust calibration ensure accurate readings even at higher turbidity levels. This wide range extends its applicability to more demanding water quality testing tasks.

  • Our Portable Turbidity Meter complies with Good Laboratory Practice (GLP) standards, making it reliable for regulatory and research-based environments. It uses the ISO 7027 formazine calibration standard and offers a seven-point calibration system for increased accuracy. Its non-linear data processing provides reliable output across a range of turbidity values. These features ensure results are consistent, traceable, and defensible in audit scenarios.

  • Yes, the Portable Turbidity Meter is ideal for remote water monitoring due to its ability to run on 5 AA alkaline batteries. It also includes an AC power option for lab use, allowing seamless switching between environments. Its lightweight design and standard carrying case make it highly portable. This versatility makes it dependable for field researchers and technicians operating in less accessible locations.

  • Labtron's Portable Turbidity Meter stores up to 20 sets of readings, allowing users to log multiple tests without immediate data transfer. This is particularly useful during extended fieldwork or batch testing processes. Stored data can be used for trend analysis or record-keeping purposes. The memory function helps maintain workflow continuity without manual logging.

  • The Portable Turbidity Meter is easy to navigate with an intuitive LCD and touch keypad, even for first-time users. Our meter's selectable automatic or manual measurement mode gives flexibility based on user preference and experience level. The auto shut-down feature adds convenience while preserving battery life.
