Product Description
Further advantages of the HYT 939 digital humidity module include:
• Calibrated and temperature compensated
• Excellent humidity/temperature accuracy and stability
• High chemical resistance
• I2C protocol (address 0x28 or alternative address)
• Wide humidity and temperature range (0 % RH to 100 % RH and -40 °C to +125 °C)
• Very low drift
• Very stable at high humidity
• Interchangeable without adjustments
• Pressure-resistant version (up to 16 bar) upon request
The digital HYT 939 humidity module is suitable for various medical systems, autoclaves, pressure dew point measurement (pressure tight packaging required), drying systems and laboratory applications.
