Rotronic Handheld Humidity and Water Measurement Devices, Sensors, and Data Loggers

ROTRONIC humidity instruments

Rotronic presents a range of data loggers, sensors, and probes for measuring relative humidity, temperature, dew point, differential pressure, flow, CO2, and water activity.

All of Rotronic’s solutions are highly accurate and are suitable for laboratories and industrial-scale food production environments. The company’s sensors are crucial for applications where constant and consistent humidity measurements are required, such as the food and agricultural industries.

Rotronic’s products are typically used to control and monitor ventilating, drying, temperature management in storage, and monitoring water activity in perishable foods.

Probes and filters for measuring humidity and temperature

In the food industry, storing food at the appropriate temperature is of paramount importance. Many foods are temperature-sensitive and if stored incorrectly may over-ripen or not develop desired flavours and textures. Chilled foods also require specific storage temperatures to slow bacterial growth and ensure safe consumption. Monitoring devices ensure precise measurements, which lead to compliance with health and safety requirements and fewer waste products.

The HygroClip 2 is a new humidity probe with high levels of accuracy and performance. It is available as both a cable probe for use in high-temperatures, or as a plug-in probe for data loggers. It is versatile, calculating humidity, temperature and dew-frost points and can work in a range of -100°C to 200°C, and 0 to 100% relative humidity (rh).

All Rotronic’s probes include Airchip3000 technology, which provides its unique calibration and adjustment process. It is responsible for the high-accuracy measurements and enables communication between the device and software or systems via wireless, USB, or ethernet.

Water activity measurements in perishable foods

Water activity has a direct influence on a product’s shelf life. Most foods have a water activity of 0.95, which can support the growth of micro-organisms. It can also affect aroma, taste, and stability. Water activity also varies with temperature, so it is as important to monitor food stored at room temperature as those in cold storage.

Rotronic offers a variety of water activity monitoring products to suit different industries and customer needs.

The Station probe HC2-AW is perfect for multi-stations as many can be connected to a single computer. It can record measurements at temperatures between -40°C and 85°C.

HygroLab C1 is effective for measuring water activity in products such as cheese, animal feed, and meat. It can also be used through a USB connection and together with the Rotronic HW4-Quick Software delivers results in five minutes.

AwTherm allows for users to carry out temperature stabilised water activity measurements, which provides an indication to its chemical, microbiological, and enzymatic stability at a specific temperature (between 0°C and 60°C). It has a removable measuring head, allowing for quick re-calibration.

Data loggers for long-term monitoring of temperature and humidity

Long-term monitoring of temperature and humidity is crucial in production, storage, and transport. Rotronic’s data loggers provide important information of how the environment changes over time, allowing for quick analysis and greater control.

Each measurement of the wireless temperature logger HL-RC-T030 is clearly time-stamped and it can consistently record for up to six years. It also has a flash memory in the event of power failure and can be positioned remotely, transmitting data up to 300 meters.

All of Rotronic’s data loggers comply with FDA 21 CFR Part 11 and GAMP 4. There is a large range of interchangeable probes, covering a variety of environments. Recorded data can be shown in a graph or table for easy analysis.
