The HygroPalm 3 series are handheld instruments with an integrated or interchangeable probe. The HP31 has an integrated probe, whilst the HP32 is compatible with all HC2A and HC2 Rotronic probes. The interchangeable probe of the HygroPalm 32 allows for a much more flexible device with a large range of probe available that connect to the probe input on the top of the HygroPalm 32. Both devices are able to perform spot measurements and logging of relative humidity, temperature and psychrometric parameters. Internal logger allows for 64,000 data points and the long-life rechargeable battery will provide up to 48 hours logging at 30 second intervals. These units replace the HygroPalm 21 and 22 units.
