The DPT-600 Plus Dew Point Meter utilizes a nano-porous metal oxide film sensor, capable of quickly and accurately measuring the dew point temperature of gases within a range of -110°C to +20°C, making it particularly suitable for low dew point measurements. The dew point meter is resistant to condensation and contamination from alcohols, natural gas liquids, H2S, and various particles. Nanotechnology has altered the critical properties of the material, enabling measurements as low as -110°C dew point. It offers an automatic calibration function and is a precise and reliable high-accuracy instrument.
