VL-Series Validatable Data Loggers
Each Veriteq VL-Series Validatable Data Logger is factory-calibrated against
National Institute of Standards and Technology (NIST) traceable standards. All
calibration information is stored digitally in the logger’s memory. For data log-
ger specifications, see www.veriteq.com or contact Veriteq.
There are many models of VL-Series Data Loggers to choose from, including
the VL-1000, VL-1400, VL-1700, VL-2000, VL-4000 and VLT series. Each
logger has one or more channels and can monitor and record data for FDA-reg-
ulated applications, including ambient temperature and relative humidity.
Many loggers can also have optional plug-in external probes attached.
