HygroPalm HP21: Humidity Temperature Handheld Indicator

The HP21 is a highly accurate hand-held indicator that displays relative humidity, temperature and the dew or frost point.

The HP21 is perfect for spot checking HVAC installations, manufacturing and storage areas, and generally for all ambient air measurement within the temperature range of -10 to 60°C.

The key features of the HP21 will meet user requirements ranging from the most basic to demanding.
The HP21 indicator has an extensive set of settings and functions that can be configured and enabled by the user with the ROTRONIC HW4 software.

In spite of its sophistication, the HP21 can still be used just as a simple humidity and temperature indicator.

Whether you decide or not to take advantage of its full potential, the HP21 will let you have it your way.

HYGROPALM21

HygroPalm handheld units are universally recognised as some of the very best available in terms of accuracy, reliability and function. 

These latest units offer a range of features unheard of only a few years ago, and in combination with a high standard of build, will provide you with years of dependable measurements. 

 With its fixed probe, the HP21 is our most cost effective instrument, yet it still boasts a ±1% accuracy specification and a PC interface for configuration and probe log data download.
