Laboratory turbidity meter LTM-02

portable

Product Overview
Labotemp Portable Turbidity Meter LTM-02 is a compact turbidity meter for accurate on-site and laboratory analysis of water clarity. It is suitable for drinking water verification, pool monitoring, environmental field surveys and industrial liquid process checks. The instrument uses an infrared LED (850 nm) and a silicon photodiode detector to provide stable, low-interference measurements across a wide range.

Operation & Functionality
The meter supports 2–5 point calibration with formazin standards and selectable units (NTU, FNU, EBC, ASBC). Measurement modes include single and continuous readings, automatic stable-reading lock and internal memory for up to 100 records. Data export is available via USB. Power options: 3 × 1.5V AA batteries or DC 5V adapter for extended field use.
