DB442 High-Temperature Humidity Transmitter

Reliable Monitoring for Environmental Test Chambers

In industries like electronics, new energy, and semiconductors, environmental test chambers simulate extreme conditions. Accurate temperature and humidity monitoring is critical—but also challenging due to high humidity (0–98% RH), wide temperatures (-40°C to 150°C), condensation, corrosion, and pressure fluctuations.

Key Challenges
Condensation: Causes drift or sensor failure
Corrosion: Moisture and gases damage probes
Pressure variation: Risks sealing and accuracy
Wide temperature range: Requires stable performance
