Extech EC700 merač kvality vody: pH, vodivosť, TDS, salinita, teplota

The Extech EC700 combines pH, conductivity, TDS, salinity, and temperature measurement in one portable, waterproof (IP57) meter. Unlike single-parameter testers, it uses a replaceable flat-surface electrode that resists breakage and simplifies cleaning, while automatic temperature compensation keeps readings accurate across changing conditions.

Highlights

• Measures pH, conductivity, TDS, salinity, and temperature
• Waterproof to IP57 standards for use in wet environments
• Replaceable flat-surface pH/conductivity electrode
• Automatic temperature compensation for conductivity, TDS, and salinity
• Large LCD shows parameter and temperature simultaneously
• Data hold and auto power off

In daily use

The EC700's flat electrode is less prone to clogging than traditional bulb designs, making it suitable for testing water, hydroponics, aquariums, and environmental samples. Calibration is straightforward with 1, 2, or 3 points for pH and a single point for conductivity. The meter runs on four CR2032 batteries, which are easy to replace.
