The HP21 is the ideal instrument for humidity and temperature measurements in simple applications. The integrated HC2 probe guarantees measuring results of the highest accuracy.
Rotronic HygroPalm HP21
Description
The HP21 is a highly accurate handheld indicator that displays relative humidity, temperature and dew or frost point temperature. The HP21 is perfect for spot checking HVAC installations, manufacturing or storage areas and any ambient air measurement within the temperature range of -10 to 60°C (14 to 140 °F). The HP21 is designed to meet a wide range of user requirements from the most basic applications to the most demanding applications.
The HP21 indicator offers 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 high end design, the HP21 is ideal even as a simple humidity and temperature indicator.
Applications
Mobile inspection and random tests in HVAC, the pharmaceutical industry and building management systems
