DX311- Digital Humidity Temp Sensor

DX311 – Digital humidity / temperature sensor (e.g. for PRO D0x)

DX 310/311 is a digital combined temperature and relative humidity probe for the PRO D01 / PRO D05 handheld meters.
The probe supplies the following calculated quantities:

• Dew point
• Wet bulb temperature
• Absolute and specific humidity
• Mixing ratio
• Specific enthalpy
• Partial vapor pressure
• Frost point temperature
• Saturation vapor pressure above water and above ice

The probe is supplied factory-calibrated in multiple points for relative humidity, and it is ready to use.
The probe can be optionally supplied with a DAkkS/ACCREDIA calibration certificate.
The calibration data are stored in the probe, allowing for interchangeability without the need for recalibration.
Equipped with 4-pin M12 connector and 2, 5 or 10 m cable (only DX311).

The DX311 is a high-precision, digital temperature and humidity sensor designed for accurate, long-term environmental monitoring in both residential and industrial applications. With digital communication interfaces and a robust design, it is ideal for integration into smart buildings, climate control systems, cleanrooms, and IoT devices.

Key Features:

• Dual Parameter Measurement: Simultaneously measures relative humidity and ambient temperature with high accuracy.

• Digital Communication: Offers UART, I²C, or RS485 output for seamless integration with microcontrollers, PLCs, or monitoring platforms.

• Wide Operating Range: Suitable for demanding indoor and outdoor environments.

• Highly Stable & Accurate: Factory calibrated with long-term reliability and low drift.

• Compact & Versatile: Slim design for flexible mounting — wall, duct, or enclosure.

• Low Power Design: Energy-efficient for use in battery-powered and remote monitoring systems.

• Optional Protective Filter: Ensures sensor stability in dusty or humid environments.
