This RS PRO hygrometer is a versatile device that allows you to take readings of barometric pressure as well as the air relative humidity and temperature. It's handheld and has a compact and robust body to ensure it's easy to use.
This device allows you to accurately measure a number of different parameters such as dew point, absolute humidity, enthalpy, saturation pressure and barometric tendency, heat index and humidex, which makes it a versatile tool you can use to collect comprehensive data. You also have an option to take maximum and minimum readings along with the time stamp so that you can record and keep track of your measurements.
The device has an alarm output function, alerting you about the parameters and a power-off function that will automatically turn off the hygrometer when you aren't using it. It complies with the United Kingdom Accreditation Service (UKAS), providing certification, testing, inspection and calibration of equipment. This ensures your measurements will be reliable and accurate.
