Product Review: New RTDs and Thermocouples

RTD | thermocouple

Not every application is the same, so you need to get the right equipment for your specific needs. When it comes to temperature measurement, inaccurate readings can severely impact your process.

So, how can you ensure you are correctly and reliably monitoring temperature?

Ashcroft has just released a new line of custom RTDs and thermocouples. Whether your application is for light-industrial temperature measurements or critical heavy-duty installations, our wide range of reliable RTD and thermocouple probes are custom-configured to meet your specific application requirements.

This article will detail several of the new probes, their features and specifications and for which applications they work best.
