Product Description

Further advantages of the HYT 271 digital humidity module include:

• Calibrated and temperature compensated

• Fast response time

• Excellent humidity/temperature accuracy and stability

• High chemical resistance

• Wide humidity and temperature range (0 % RH to 100 % RH and -40 °C to +125 °C)

• Very low drift

• I2C protocol (address 0x28 or alternative address)

• Very stable at high humidity

• Interchangeable without adjustment

    The digital IST AG HYT 271 humidity module is suitable for various handheld measurement instruments, humidity transmitters, industrial applications, measuring technology and HVAC applications.
