The new Marathon MM Series platform, which covers a temperature range of minus 40 to 3000°C (minus 40 to 5432°F), consists of five IR temperature sensor models, each with a specific measurement wavelength and temperature range appropriate for either low- (minus 40 to 800°C / minus 40 to 1472°F), medium- (250 to 1100°C / 482 to 2012°F), or high-temperature (300 to 3000°C / 572 to 3273°F) production monitoring.
The Marathon MM now features Precision Variable Focus that allows fast, easy and accurate adjustment of the focus of measurement targets, either by push-button at the rear of the instrument or remotely via an RS232/RS485 PC connection, where adjustments can be seen real-time through video. Sensors with variable focus option can be configured according to each application requirements reducing the installation time and chance for incorrect installation.

 The CI Series Compact Infrared Sensors accurately and repeatably measure the amount of heat energy emitted from an object and convert the energy into a measurable electrical signal. The CI measures target temperatures ranging from 0 to 500°C (32 to 932°F). The onboard electronics are protected by a rugged IP 65 (NEMA-4) stainless steel housing, allowing the sensor to function in ambient temperatures to 70°C (160°F) without cooling. With water cooling, the CI can withstand ambient temperatures up to 260°C (500°F).

 The GP Series is a versatile, two-piece temperature monitoring system that combines a compact monitor and an infrared sensing head. The heart of the system, the 1/8 DIN GP monitor, provides advanced infrared processing capabilities including peak and valley hold, averaging, and a user-adjustable offset. The rugged Thermalert GPR/GPS sensors are available with standard or close focus optics, and provide target temperature readings with 1% accuracy. The Thermalert GPM is available with preinstalled cable.

 The Raytek MI is a two-piece infrared temperature measurement system with a miniature sensing head and separate electronics. The miniature sensing head is small enough to be installed just about anywhere, but performs as well as much larger and more expensive systems. Easily adjust the MI signal processing electronics, which include Emissivity, Peak Hold, Valley Hold, and Averaging functions, on the 5-digit LCD user interface. Ideal for use in the paper, printing, converting and food processing industries.
