  • Rugged Aluminum Enclosure
PL-TW is an 8-channel, battery powered, standalone and WiFi-enabled thermocouple data logger. Part of the Precise Log family of WiFi data loggers, the PL-TW records eight external thermocouples and saves data in 8-MB memory. Embedded WiFi module allows remote data monitoring and downloading. The data logger can be enabled by Modbus TCP protocol and become a Modbus TCP server.  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 and more.


High Data Resolution
The 16-bit analog-to-digital converter meets most high-resolution requirements.

Large Memory Size
The 8-Mega-Byte Memory stores years of measurements,

Easy Access
One Plug & Play USB port makes communications with PC SiteView software super easy. On-board WIFI module creates WIFI access point or connects to local network wirelessly, allowing remote monitoring and downloading.

10-Year Battery Life
The internal lithium battery provides over 10 years of instantaneous logging operation when sampling at an interval of one minute.  The battery does not require re-charging but by using the included USB cable the PL-TW can run from external power preserving the internal power (typically only needed for sampling at high sample rates for extended time periods).

2-IN-1 Design
The logger can operate as portable standalone data logger and be powered by internal battery. Or when powered by external 5VDC power supply, the logger automatically connects to WIFI network and be ready for remote access.

Rugged Physical Housing
The rugged aluminum enclosure makes the PRECISE-LOG data loggers perfect in the harshest industrial environment.

SiteView Software

SiteView Software
SiteView is an optional PC based application works with all Precise Log (as well Site Log and iLog ) data loggers for downloading, configuration and data analyzing and plotting. Its user-friendly graphic interface plus powerful functionalities fit both novice and advanced users. The versatility of custom equation and custom-line equation handle complicated measurement requirements. SiteView is compatible with Window XP, Vista, 7, 8, 10 operating systems.

  • Real-time view and chart recording replaces chart recording device
  • Custom equation and custom-line equation solves scientific and laboratory algorithm difficulties
  • Zoom in/zoom out, annotation/label of graph functions provide detailed view of data
  • Multiple file loading allows easy data comparison
  • Dynamic statistics provides detailed information of current zoomed view
  • Scheduled Download automatically backups data regularly to system database
  • Export to CSV, TXT, BMP, JPG, TIF, PNG, GIF file formats
