Data Logger
Tpaq21

Compact, highly sophisticated and accurate, this logger records 130,000 data readings over 10 selectable channels.

Variable sampling intervals and multiple event programming provides detailed analysis where heat treatment processes are followed by fast moving sections of the product temperature profile, such as gas or water quenches.

The Tpaq21 is equally at home in ceramics processes such as brick and sanitaryware firing, where long duration runs at high ambient temperatures call for high memory capacity and rugged electronics.

Combined with a built-in transmitter to see these processes in real time, this is an ideal data logger for all applications.

Highlights:

  • Ten thermocouple channels for maximum data collection on each run.
  • Huge memory capacity: 130,000 data points for detailed process analysis.
  • Sampling intervals down to 0.1 seconds to collect maximum data in minimum time.
  • High accuracy: to +/- 0.3°C / 0.5°F for compliance to tight specifications.
  • Hot data protected by non-volatile memory or software warning if reset is attempted before download.
  • USB & RS232 communication for rapid data download to laptops.
  • Radio Frequency (RF) telemetry or hard wired data acquisition for monitoring in real time with full analysis functions and alarms to alert if the process is out of specification.
  • Four status LED's to show the exact logger activity after disconnecting from the computer.
  • Push start/stop buttons for easy user control.
  • Two battery types for operation in normal and high ambient temperatures.
  • Rugged industrial case and electronics allows operation in harsh furnace and kiln environments of dust, pressure, and vacuum.
  • 'Multiple events' allows sampling interval change during the run, ideal for water and gas quench processes.
  • Reset by start button after download for speed and simplicity.
