One AA battery and NIST-traceable calibration certificate with data.
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.
