This portable combination meter is ideal for science classrooms and labs, allowing teachers and students to measure pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature with a single device. Designed for ease of use, it supports accurate water quality analysis in practical experiments for secondary schools and colleges.

• Measures pH (0.1 resolution, ±0.1 accuracy), EC (0.00–4.00 mS/cm, 0.01 resolution), TDS (0–1999 ppm, 1 ppm resolution), and temperature
• Large, easy-to-read LCD displays readings and calibration instructions
• Manual single-point calibration for pH and EC/TDS
• Supplied with a durable 3-in-1 probe (polypropylene body, stainless steel pins, built-in temperature sensor)
• Battery life indicator and on-screen tutorial messages
• Water resistant for reliable classroom use
