This thermohygrometer records data onto a standard SD memory card instead of built-in memory - the advantage being that when the memory on the SD card is full, the SD card can be simply exchanged out for unlimited data storage. The data is provided in a text report that includes date, time of day, and readings of sensors, and may be sent to any spreadsheet or database. The unique 4-line display simultaneously shows ambient temperature, humidity, dew point, and time of day. An audible and visual alarm alerts you when temperature, humidity, or dew point levels are higher or lower than the programmable set points. User-settable parameters include date, time, sampling time, temperature unit of measure, high/low alarm set points, and auto power off.

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.
