Overview
The HygroPalm is a portable humidity temperature indicator that is available with a wide variety of probes
for use in many different applications such as the spot check measurement of HVAC installations and
manufacturing processes, the measurement of seeds, pharmaceutical powders and other materials in
bulk, the measurement of paper stacks and rolls, etc. The HygroPalm operates with a regular 9V alkaline
battery or with a rechargeable 9V battery.
The HygroPalm is available in 3 different models:
HygroPalm 1 – basic indicator
- single probe input, compatible with any ROTRONIC HygroClip digital probe
- indication of relative humidity, temperature, dew point or wet bulb temperature
- 1-point software-based probe calibration
- remote mode reads the measurements from any ROTRONIC HygroFlex transmitter
1)
1) this is especially useful when the transmitter does not have a display - optional connecting cable required
HygroPalm 2 – standard indicator
- accepts up to 2 ROTRONIC HygroClip digital probes
- indication of relative humidity, temperature, dew point, wet bulb, mixing ratio, enthalpy, etc., or
user defined calculation such as the difference between temperature and dew point
1)
- software-based probe calibration (1-point or multi-point)
- remote mode reads the measurements, configuration and status from any ROTRONIC HygroFlex
transmitter
2)
- remote mode allows a 1-point calibration of a ROTRONIC HygroFlex 2 or 3 transmitter, using any
probe connected to the HygroPalm as a reference
2) 3)
- RS232 digital port for connecting to the COM port of a PC
4)
1) uses a fixed barometric pressure value for those parameters that require pressure as a computational input.
The fixed pressure value can be changed with the optional HW3 or HW4 software.
2) this is especially useful when the transmitter does not have a display - optional connecting cable required –
this function is not available with the HygroFlex 1
3) applies only to the ROTRONIC HygroClip digital probes
4) requires optional connecting cable and HW3 or HW4 software
