The Traceable WD-20250-40 Temperature/RH Touch Screen Recorder is a tablet-based instrument that measures, displays, logs temperature, relative humidity and dew point conditions. Measured values are simultaneously displayed both graphically and digitally on a high-resolution color touch-screen display. Monitor conditions related to pharmaceutical, food, and chemical processing and storage. Also ideal for use in greenhouses, museums, laboratories and warehouses.

Monitor and log environmental conditions in food, pharmaceutical, laboratory, green house, museum or other sensitive areas. A 110VAC adapter powers the instrument and a 2500mAH on-board battery provides backup up to six hours in case of power interruption.

The WD-20250-40 mounts on a wall using included bracket. A built-in stand allows the instrument to also be set on a horizontal surface. The temperature/RH sensor plugs directly onto the back of the tablet or can be positioned remotely with use of a 6’ extension cable which is included. Additional 20250-47 extension cables, sold separately, can be linked to extend the sensor up to 18’ from the instrument.

Operation is very simple out of the box. Push the on/off button and the resident operating software self-boots. Set up data logging attributes including sample frequency, sample size, alarm settings, and units of measure through an intuitive touchscreen menu. The instrument can be placed in real-time mode or set to start logging at some future time.

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 users both time and money by not having to calibrate separately.
