Digi-Sense, 68000-49, Traceable Digital Barometer with Calibration, NIST CertificateFeatures with all optional accessories:Ideal for monitoring environmental conditions in plants and labsGet accurate, reliable measurements with included NIST-traceable calibrationMeasure barometric pressure, temperature and relative humidity with this all-in-one meterView current barometric pressure trends in bar graph format for the past 1 to 24 hoursEasily view Min/Max for all parameters and set high and low alarm set pointsConnect and download real-time readings to a PC with the data acquisition softwareRange: 500 to 1030 mbar (14.77 to 30.41 inHg)Includes:wall mountflip-open standthree AAA batteriesNIST-traceable calibration certificate with dataThis digital barometer is great for measuring barometric pressure, temperature and relative humidity in ambient environments. Additionally, the large four-line LCD also displays barometric pressure trends in bar graph format and time of day. Minimum/Maximum readings for all three parameters are automatically stored internally each hour and can be recalled for the past 24 hours. High and low audible and visual alarms may also be set for pressure, temperature and humidity conditions. 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 are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately. NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.Unit does not read in psi, but in mbar and in. Hg. Pressure range provided in psi is for comparison purposes only.
