Measure where standard loggers cannot operate.
Monitor ultra-low freezers and high-temperature processes with external probes while keeping the display and electronics in a safer location.
THE APPLICATION
Put the probe in the process and keep the logger accessible.
Extreme environments require the correct probe, cable and operating range. External-probe models separate the sensing point from the display and controls.


Correct measurement range
Select a probe and logger combination for the real operating limits.
Safer operation
Keep the main unit outside the chamber for easier reading and handling.
Useful records
Capture trends and alarms without interrupting the monitored process.
HOW IT WORKS
A clear monitoring plan from setup to report.
We help match the logger, sensing range, alarm limits and reporting method to the way your team actually works.
Confirm the range
Define minimum and maximum temperature, duration and response needs.
Select and install
Choose the probe, cable and mounting approach for the equipment.
Record and report
Monitor the process and export data for review and archiving.
RECOMMENDED MODELS
Start with the right format for the job.
The final model and configuration depend on your monitoring range, duration, environment and reporting requirements.
