Frequently Asked Questions

Your Veriteq documentation occasionally lists accuracy figures of ±0.10°C for temperature and ±1% for RH, but also ±0.15°C and ±2%RH. What is correct ?
Actually, both figures are correct. Veriteq data loggers are designed and calibrated to be accurate to within 0.10°C / 1% RH (relative Humidity,) placing them amongst the most accurate battery operated data loggers in the world.
Temperature and above all humidity sensors, however, can change with age, so it is important for the user to know what accuracy the unit will maintain after one year's use, the typical annual recalibration period. Veriteq guarantees an accuracy of 0.15°C / 2% RH (!) after one year when properly used.

PoE is the acronym for Power over Ethernet and describes a system to transfer electrical power, along with data, to remote devices over standard twisted-pair cable in an Ethernet network without the requirement for mains power. Power is fed into the net at any point, often at the server side to make use of the server's backup power.
This doesn't immediately concern Veriteq data loggers due to their internal 10-year life battery. Still, connecting the data loggers to the IT infrastructure via an Ethernet device offers two advantages: Firstly, no local mains power is required and secondly, PoE can easily be maintained via the emergency backup supply.

Yes ! Veriteq data loggers are calibrated in Veriteq's own A2LA accredited DIN EN ISO/IEC 17025 laboratory, traceable to international standards. A2LA is the North American equivalent to the German DKD, the Suisse SAS or the Austrian BMwA, all of whom recognize each others accreditations.

Many loggers available in today's market suffer battery problems resulting from two main causes: battery life and battery contact issues.
Each case can result in data loss or incomplete recordings should the logger cease to function correctly in the middle of an important validation run. Reliable predictions about when this might happen are next to impossible, as most batteries can hold their voltage near 100% for almost all their life, only to drop suddenly near the end.
The electronics of the Veriteq data loggers are optimised right down to the last detail, so they can operate with minimal power consumption. This results in a 10-year battery life, offering safety and reliability for many years to come. As a positive side effect of the extremely long life battery contacts can be soldered to the electronics, making all contact problems resulting from oxidization or shock a thing of the past.
