Hygropin Relative Humdity Meter

INTRODUCTION

Hygropin comes with a small, fast sensor making it the perfect solution to identify and monitor moisture in concrete quicker and easier than ever before. The Hygropin provides the smallest available sensor on the market, minimising damage to the surface and reducing the installation efforts immensely. Due to the small air volume of the test sleeve, the humidity equilibrium process is extremely fast.

APPLICATIONS

The relative humidity test outlined by ASTM F2170 requires placing a measuring sleeve at a specific, well defined depth in the concrete. This can be done either by drilling a hole or pre-installing cast holes in fresh concrete. Proceq offer the best solution for both procedures.

Surface based testing methods only measure up to 20mm at best and don’t essentially reflect reality. Hygropin uses the insitu technology which identifies the actual moisture content inside the concrete.

BENEFITS

Comfortable: Two independent sensor channels can mea¬sure ambient and concrete characteristics simultaneously.
Wide Measuring Range: Measures relative humidity, tem¬perature, dew/frost point, etc.
0…100 % RH / -40…+85 °C
Accuracy: The Hygropin combines the highest measure¬ment accuracy with a fast response time.
Minimal Invasive: Highly integrated sensor with only 5 mm diameter for minimal efforts on site.
Durability: Stainless steel housing of the sensor for long lasting performance in rough environments.
Data Logging / Storage: The Hygropin can record data over a period of time for traceable information.

USER INTERFACE

Depending on the settings the Hygropin is able to display:

Relative humidity and temperature measured by two probes.
Calculate parameters like dew/frost point etc. for both probes.
Difference between the values measured by the ambient and insitu probes.
Trend indicators for each parameter.

INSITU AND AMBIENT PROBE

Insitu Probe

Highly integrated temperature and humidity probe which combines accuracy, wide measuring range and long term stability. The stainless steel housing fits perfectly to the rough environment on the construction site. Probe and instrument are connected with a 2m cable.

Ambient Probe (optional)

Directly connected to the instrument, the ambient probe simplifies capturing the environmental parameters. Both temperature and relative humidity are measured as precisely as with the insitu probe.
