HygroPalm — Handheld Humidity & Temperature Measurement Instruments
Portable climate measurement you can trust — wherever you go
When you need accurate, reliable humidity and temperature readings on the move, the Rotronic HygroPalm series delivers flexible, field-ready handheld solutions. Designed for inspection, spot checks, maintenance, and quality control across industrial, commercial, and scientific environments, HygroPalm instruments are lightweight, ergonomic, and packed with functionality to help you collect the right data at the right time.
The HygroPalm family includes two key variants — the HP32, a flexible probe-compatible handheld meter, and the HP-GTS, a robust instrument tailored for specific industry needs like paper product humidity measurement.
HygroPalm HP32 — Versatile Handheld Humidity & Temperature Meter
The HP32 is a high-accuracy, portable humidity and temperature analyzer compatible with a wide range of Rotronic HC2A and HC2 probes (except HC2-LDP), making it ideal for applications where measurement reliability and flexibility are essential.
Key Features:
- Probe compatibility: Works with all Rotronic HC2A and HC2 probes for different ranges and environments (probes sold separately)
- Multi-parameter readings: Measures relative humidity, temperature, and performs psychrometric calculations such as dew/frost point, wet bulb, enthalpy and more
- Data logging: Internal memory for up to 64,000 data points with programmable logging intervals
- Graph display: Graphical LCD for viewing up to 4 values and trend indicators
- Portable power: Long-life rechargeable battery (up to ~48 h logging) and USB-Micro interface for charging and PC connectivity
- Visual and audible alarms: Set alarms on any value for quick field alerts
- Free software: Includes HW4 Lite for data download and analysis
Why HP32 matters for you:
- Flexible for field inspection across HVAC, building management, food & pharma environments
- Spot checks and trend logging on site without a laptop connected
- Easily updateable and expandable as your monitoring needs evolve
HygroPalm GTS — Robust Field Meter for Specialty Applications
The HygroPalm GTS model is a tried-and-tested handheld instrument primarily designed for equilibrium relative humidity and temperature measurement in specific industrial contexts — especially in the paper and cardboard industries where layered material humidity profiles matter.
Key Features:
- Fixed “sword” probe: Designed for swift and reliable contact measurement in materials such as paper stacks and similar composites
- Trend indicators: Visual tracking of changing humidity and temperature over time
- Data logging: Allows spot checks and short-term record keeping during manual inspection
- Software support: Compatible with free HW4 evaluation software for download and report creation
Why GTS matters for you:
- Purpose-built for industries like paper, packaging and material science
- Quick assessment of moisture content in stacks and bulk products
- Ideal where fixed probe simplicity and rugged performance are priorities
