Dew Point Micro Moisture Meter | Resistance Capacitance PP20 Conversion | Vaisala 143 KST-VII

Product Overview

This precision dew point meter integrates an imported Vaisala 143 capacitance-resistance sensor, delivering high-accuracy measurements and rapid response. Engineered for trace moisture analysis, it supports real-time display of dew point (-8 to +20°C Td), PP20, PPMV, temperature, and flow rate via an 800×480 high-definition touch screen. Its self-locking quick connector enables plug-and-play field operation, while a lithium battery ensures >8 hours of continuous use for outdoor applications. Compliant with DL/T1366-2023 standards, it suits moisture detection in compressed air, SF6, N2, and H2 gases.

Key Advantages

Self-Calibration System:Maintains accuracy without external tools.
Multi-Parameter Tracking:Dynamic curve display for real-time measurement trends.
Dual-Power Flexibility:Lithium battery with AC/DC backup for extended field use.
Data Management:USB download, thermal silent printing, and large-capacity storage.
Probe Protection:Automatic self-protection for prolonged sensor lifespan.
