68000-51 Digital Barometer Data Acquisition System by Digi-Sense

Use this data acquisition software and USB cable to permanently capture real-time measurements on your PC from up to eight different Traceable barometers. Data can then be saved, viewed, printed as-is, or merged into a report or spreadsheet and e-mailed to any smartphone or computer. The software also features its own 24/7 audible and visual alarm to remind you to check on data.

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.

• Set high and low alarm set points
• Connect and download real-time readings to a PC
• Get reliable readings
• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory

90550-81 Dampen Adjustable Angle Bimetal Thermometer 5" Dial 24" L Range 0-250F/-20-120C by Digi-Sense

Accuracy is ±1% full-scale when stem is immersed 2" in liquids or 4" in gases (immerse models with a 2.5" stem length 2" in gases). Measured stem length from the top of the threads to the bottom tip of the stem. Stem dia is 0.25"; threaded connection is 1/2" NPT(M). All thermometers meet or exceed ASME B40.3 standards. Maximum environmental temperature for glass lens thermometers is 500°F (148°C).
