Product Information

Accurate, Rugged, and Easy to Read

Plus Connects to Your Computer for Data Logging and Graphing!


The HS-1 Thermo-Hygrometer from Phoenix is highly accurate and easy-to-read. It features a large, 2-line color display and calculates in real time the current temperature, relative humidity, GPP, and dew point.


The HS-1 shows the current job site conditions, plus it can store a saved value (such as an unaffected area reading) for referencing later. The HS-1 will automatically calculate the minimum (MIN), maximum (MAX), and average (AVG_ measurements from the point it is turned on, giving you the accurate calculations you need to effectively monitor every drying job. It also offers a convenient HOLD function for taking readings in areas where the meter face is not readily visible.


A convenient “Lock” feature allows you to lock the button panel to avoid accidentally pressing buttons.


When not in use, the unit automatically powers off to conserve battery life.


The Phoenix HS-1 features a USB connection, allowing you to connect the unit to your personal computer for data logging and graphing. The HS-1 interfaces with SmartGraph3 software, a free download available from Phoenix.


Accurate measurements of the following:

  • Temperature
  • Relative humidity 
  • Grains per pound (m3, kg, lb)
  • Dew point (°F/°C)
