Hygrometers for Temperature and Humidity Monitoring

A hygrometer measures relative humidity and often temperature in the air, used for environmental monitoring in warehouses, labs, and cold chain logistics. A hydrometer, by contrast, measures the specific gravity or density of liquids, commonly used in brewing, winemaking, or battery acid testing. The two devices serve entirely different purposes despite similar names.

Single-use hygrometers, like the TempTrail Rh-S, are designed for one recording cycle and are ideal for shipments where the device isn't returned. Multi-use models, like the Rh-M, feature replaceable batteries and configurable settings, allowing repeated deployment for internal warehouse or facility monitoring, offering better long-term cost efficiency.

TempTrail hygrometers offer temperature accuracy of ±0.2°C/°F and humidity accuracy of ±2% RH, with resolutions of 0.1°C and 0.1% RH respectively. This level of precision meets the demands of pharmaceutical, food, and cold chain applications where small environmental deviations can impact product quality and regulatory compliance.

Yes, TempTrail devices automatically generate PDF reports and CSV data files upon USB connection, requiring no external software installation. This streamlines documentation for FDA 21 CFR Part 11 compliance, making it easy to produce audit-ready records for pharmaceutical, food, and laboratory quality control processes.

Industries including pharmaceutical cold chain, food and beverage logistics, medical laboratories, aerospace, and industrial warehousing rely on temperature and humidity data loggers. These sectors require precise environmental monitoring to protect sensitive goods, maintain regulatory compliance, and ensure product quality throughout storage and transportation.

Recording duration depends on the configuration; the single-use TempTrail Rh-S logs for up to 100 days at a standard 10-minute interval, while the multi-use Rh-M offers user-configurable intervals and durations based on battery life and storage needs, supporting up to 32,000 combined data points.
