Hygrometers
Hygrometers
Instruments that measure moisture in ambient air; types include indicator papers and dial-styles; electronic versions may be analog or digital; may be traceable to NIST. Because humidity is affected by temperature, most hygrometers include thermometers to correct readings.
Hygrometers, or humidity meters, are devices for measuring the level of water vapor (also known as relative humidity, RH) in the atmosphere or in other gases.
How Are Hygrometers Used?
• Monitoring moisture levels in laboratory incubators, growth chambers, greenhouses, and controlled climate cabinets
• Measuring humidity in confined spaces, rooms, or buildings where moisture levels are critical to the activity being performed or to the objects or materials being stored
• Measuring humidity in domestic or residential settings
• Meteorological and climate monitoring
Classical, mechanical hygrometers, which are less widely used today, include wet/dry bulb hygrometers or psychrometers and hair tension hygrometers, which rely upon a single (hygroscopic) hair or fiber.
Most hygrometers available on the market today are electronic digital instruments, which measure humidity using capacitive or resistive sensors. These digital devices offer clear displays with reliable and consistent performance, and are typically compact, hand-held, or benchtop units with a minimal footprint. They may also be available with temperature, timer and alarm functionality, and with externally corded probes and wireless radio-signal connectivity for remote monitoring and data logging. Many operate over a wide temperature range of -5° to +50°C, with a typical measurement range of 0 to 95% relative humidity (RH).

Fisher Education™ Traceable™ Precision Monitoring Thermohygrometer with Calibration
Simultaneously display min/max and current temperature and humidity with 7-day graph
Cole-Parmer Traceable Thermometer with Clock, Humidity Monitor, and Calibration
Unique unit simultaneously displays time-of-day, temperature, and humidity. Clock displays AM/PM or 24-hour military time to the exact minute with 0.01% accuracy. Noting changes is easy with triple display. Internal sensors make it ideal for use in hoods, storerooms, clean rooms, incubators, drying chambers, and environmental cabinets. Temperature range is 32.0 to 122.0F and 0.0 to 50.0C. Resolution is 0.1 and accuracy is 1C. Relative humidity range is 20 to 90%. Resolution is 1% RH and accuracy is 5% RH mid-range, otherwise 8%. At the touch of a button, memory recalls highest and lowest temperature and humidity readings.
Cole-Parmer Traceable Digital Thermohygrometer with Dew Point, Wet-Bulb, and Calibration
This thermohygrometer monitors temperature, humidity, dew-point, and wet-bulb. Displays current conditions along with minimum, and maximum readings. Settable high/low alarm for all four readings (dew-point, wet-bulb, humidity, temperature) may be set in 0.1 increments, and will sound for one minute and red LED will flash until readings return to non-alarm condition. Traceable Products have an individually-numbered Traceable Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.
