Ethernet Temperature & Humidity Data Logger
Place these data loggers throughout your facility and receive all data automatically at your PC. No retrieving data from loggers. This is the easiest and most cost-effective way to create a scalable monitoring network. Compatible with Replaceable Sensors which make calibration easy and fast. Simply order a new sensor with a calibration and you can swap out the old for the new eliminating any downtime and keeping you in comliance.
- New Replaceable Sensors
- Email and Text alerts available
- Eliminates the need to change charts and pens
- Data automatically downloaded to your computer wirelessly
- Loggers continue to log in the event of a power outage
These loggers, while wired, are compatible with the WiZARD2 monitoring system and software. Use them in conjunction with your WiZARD2 system or without! They allow you to monitor locations that would have previously been cost prohibitive to monitor wirelessly. Additionally, the extension probe shown in the images is an optional accessory: A895.
DicksonWare Software is needed to communicate with this product and is sold separately.

Why should I calibrate?
All instruments lose accuracy over time due to normal usage and the environmental conditions to which they are exposed.
How often should I calibrate?
For most applications, the recommended calibration interval is every twelve months.
What is NIST Calibration
NIST stands for the National Institute for Standards and Technology. This organization is responsible for maintaining the master for different measurements, such as the standard "foot", standard, "second", or standard "pound". NIST also maintains the standard for temperature, humidity and pressure.
NIST Traceable means that the measuring standard can be traced directly back to the master standard maintained by the NIST organization.
NIST-Traceable does not tell you the measurement accuracy of a metrologty service in any detail. Only metrology services that can document their ISO 17025 standard provided data on their best measurement uncertainty.
