WD-20250-48 Replacement AC Adapter for Temperature/RH Touch Screen Recorder by Digi-Sense

Accessories to support your 20250-40 Digi-Sense Temperature Humidty Touchscreen Recorder.

90225-29 Carrying Case for Scientific Thermometer, Padded Nylon by Digi-Sense

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.

• Replacement Probe for 90225-27
• Helps protect you meter while being stored

Includes

probe only.
