Product Description

Our firm is successfully associated in the industry as one of the praiseworthy importers and exporters of The Universal Transmitter. This transmitter is specially utilized for transmitting data with modems and other serial devices. Offered transmitter is designed at our well-furnished manufacturing unit utilizing the advanced technology under the vigilance of our diligent experts. To facilitate the assorted requirements of our precious patrons, we offer this the universal transmitter in several technical specifications at reasonable price.

Easy to read display :

  • Display of the measured values on a clear, backlit graphic display with trend indicators
  • Configuration by keypad possible

Tried-and-tested housing :

Robust industrial housing

Wall or duct mount versions

Output signals :

  • Two freely selectable and scalable analog outputs
  • 2-wire and 3/4-wire systems available
  • Optional digital outputs allow integration on a network via RS485 or Ethernet wire or wireless

Fast response and precision measurement :

  • Integrated probe
  • By decoupling the Pt100 temperature sensor from the probe, thermal response is significantly improved
  • Heat from the electronic components is not transmitted to the sensors, thereby improving the accuracy of the system

AirChip3000 :

  • Compensates humidity and temperature over 30,000 reference points
  • 2,000 data point memory
  • Dew/frost point calculation
  • Sensor auto-diagnostics and automatic correction
  • Active alarming and information
  • ASIC (Application Specific Integrated Circuit), micro-controller and EEPROM on one chip


The HygroFlex4-series is ideal for all applications where exact measurement of humidity and temperature is of decisive importance. The transmitters can be used in a variety of fields for heating, ventilation and air conditioning applications, greenhouses, museums, warehouses, libraries, railway stations and for climate control in office buildings.

Thanks to the exceptional long-term stability of the sensors and auto-diagnostics, the transmitters are both service-friendly and reliable, thereby saving you time and money.
