NOTE: Requires the Siteview software, sold separately.
The VL-WF-TH WiFi Thermistor Data Logger is an 8-channel, battery-powered, standalone, and WIFI-enabled thermistor data logger. The logger measures eight external thermistors and saves data in 8 megabytes of memory.
Embedded WIFI module allows remote data monitoring and downloading.
16-bit ADC makes it well suited for science and laboratory applications where precise and accurate measurements are critical.
Its aluminum enclosure makes it excellent in the harshest industrial environment.
Simply power the logger in WIFI covered area and access it from your computer for configuration, downloading graph viewing, etc.
Features:
- The 16-bit analog-to-digital converter meets most high-resolution requirements
- 8-megabyte memory stores up to 4 million measurements
- Eight external thermistor/resistor inputs
- Both USB and WiFi (requires external power) interfaces
- Wide sampling interval selections (1 second to 12 hours)
Memory Capacity
All VersaLog data loggers come with 8MB onboard flash memory. The following table shows the relationship between the number of enabled channels, sampling interval, and max time span of logging.
