Product Overview

The Ultimax® series are handheld, portable infrared pyrometers designed for maintenance applications and verification of process temperatures. For users that need temperature reporting capabilities, the Ultimax infrared thermometer can be used in datalogging mode to store up to 1000 temperature measurements. Ultimax data analysis software can then be used to graph, display, or export this temperature information.

Sophisticated microprocessor-based electronics allow simple push-button selection of emissivity, response time and measuring mode. Single lens reflex (SLR) optics and a reticle that precisely defines the measured area deliver ultimate accuracy. Both analog and digital outputs are standard features and the temperature values are displayed both in the viewfinder and on the external LCD. Reliability is enhanced by surface mount technology, DC operation and an optical system that does not require optical modulation techniques, such as mechanical choppers.

The Ultimax infrared thermometers measure the temperature of an object directly, but without contact. They provide the ideal solution for temperature measurement of objects that are fragile, moving, far away, or behind a protective window – as in a vacuum chamber or controlled atmosphere furnace. With Ultimax, you get all the benefits of noncontact infrared temperature measurement:

  • Accuracy – heat is not removed from the measured object (as with contact sensors)
  • Speed – response times are faster, in milliseconds (not seconds)
  • Quality – without contact, damage and contamination of the measured object is eliminated

The Ultimax Plus series features four models, including a two color ratio series that can be used as a one or two color sensor. All Ultimax models can save up to 500 data points and include Peak Picker, Valley Picker and Averaging filters. The Ranges are capable of being scaled for analog or digital outputs and ºF or ºC are field selectable.


Digital and analog cables, optional close focus lenses and other accessories are available for the Ultimax series of IR sensors.
