Accurate Hygrometers
Accurate hygrometers are ideal for measuring and monitoring humidity levels in the air. Monitors are suitable for usage in chemical storage areas, stock rooms, clean rooms, factories, or outdoor spaces. They are available in multiple sizes from Thomas Scientific, including pocket-sized options and numerous display sections to provide three current readings.
Accurate hygrometers are ideal within the lab for preventing mold and mildew growth by maintaining appropriate humidity levels and improving air quality. Features on various models include a digital display providing easy-to-read and recording humidity levels quickly and accurately. Analog hygrometers can be easily calibrated or adjusted to ensure accuracy over time. Some models allow users to do this, while others may require it. Accurate humidity sensors carry high-precision sensors that provide precise and reliable measurements.
We also carry a range of air samplers.
