The Traceable Memory-Loc Dual Zone Temperature Monitoring & Data Logger Kit provides accurate temperature readings, ideal for monitoring two temperatures while storing vaccines or other important samples. The triple digital display shows high, low and current temperatures (both probes) allowing for quick, easy reading, while the data logging feature monitors the high and low readings in 1 minute intervals. VeriCor is a proud distributor of Traceable products. Each Data Logger includes a unique Calibration Certificate. 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.
