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. 

These loggers are 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 compliance.

The WH345 transmits data wirelessly, and requires no hard wiring.  The WH645 transmits data via Ethernet and while wired, is compatible with the WiZARD2 monitoring system and software. Use it in conjunction with your WiZARD2 system or without! It allows you to monitor locations that would have previously been cost prohibitive to monitor wirelessly.

• New replaceable sensors
• Email and text alerts available
• Wireless or Ethernet data transmission
• 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
