Temperature and Humidity Logger DL2000
Vaisala’s DL2000 data loggers were developed with the aim to provide the highest level of accuracy for monitoring temperature, relative humidity and an analogue signal of your choice. They are the industry leaders and a superior alternative to data recorders and hard-wired systems.
System features:
- Adjustable recording intervals
- Long-life battery with a 10-year life
- NIST traceable, A2LA accredited calibration available
- Utilization of Steinhart-Hart coefficients stored in each data recorder for high system accuracy
- Integrated, high-precision, capacitive thin-film polymer humidity sensor
- Snap-in logger cradle for easy network connectivity
- Timebase calibrated over the operating temperature range
- Optional: Analogue inputs available
Data Loggers VL-Series
Combined with the vLog VL software, the VL logger models provide a superior, high-accuracy solution for use in FDA/GxP regulated environments by providing tamper-proof files and encrypted electronic records that meet 21 CFR Part 11 requirements.
Data Loggers SP-Series
The SP models provide a compact, easily-deployable, highly accurate measurement and recording device for use in non-FDA/GxP regulated industries. Coupled with vLog SP software for downloading, displaying and analyzing of recorded environmental data -including reporting- the SP models were designed for use in non-FDA/GxP regulated environments.
