Stable and Accurate Dew Point Monitoring for Industrial and Environmental Applications
The HG602-D is a compact, high-reliability transmitter for dew point, temperature, and humidity measurement in environments up to 60 °C (140 °F).
-It delivers ±2 °C Td accuracy, fast response, and long-term stability, making it ideal for compressed air systems, HVAC monitoring, and industrial drying processes.
-The sensor’s condensation-resistant design ensures accurate readings even under high humidity or fluctuating ambient conditions.
Key Highlights:
*Operating Temperature: −40 ~ +60 °C
*Dew Point Range: −60 ~ +60 °C (−76 ~ +140 °F)
*Accuracy: ±2 °C Td (±3.6 °F)
*Output Options: RS-485 (Modbus-RTU) + 4–20 mA / 0–5 V / 0–10 V
*Condensation Resistance: Sensor remains dry and stable under high humidity
*Wide Power Supply: 10 – 28 V DC with polarity protection
*Strong Compatibility: Standard Modbus protocol for seamless system integration
