NEO-1D with an e-ink display and NIST-traceable calibration. Wirelessly monitors temperature, humidity, VPD, heat index, and dew point for up to 3+ years on battery power — with the calibration certificate regulators require.
Calibration traceable to the U.S. National Institute of Standards and Technology. Tested and verified at multiple points across the operating range; certificate archived in iMatrix Cloud for the life of the device.
3+ temperature points verified across the operating range — not a single midpoint check.
Calibration performed by accredited labs traceable to NIST national standards.
Live readings on the e-ink display for spot checks, certificate in the cloud for audits.
