The PPM-TDD1A liquid-cooled conductivity sensor employs advanced anti-polarization and signal isolation technologies to effectively eliminate external interference, ensuring precise and stable performance even in complex electromagnetic environments; it also integrates a temperature sensor to enable real-time, automatic measurement compensation. Easy to install and compatible with various media—such as propylene glycol, ethylene glycol, and deionized water—it provides reliable safety assurance for liquid cooling systems.
■ Compact size, easy to install
■ Ultra-low conductivity (≥2 μS/cm)
■ Highly responsive and accurate
■ Corrosion-resistant
■ Built-in temperature sensor for real-time temperature compensation
