Product Description

The new Marathon MM Series platform, which covers a temperature range of minus 40 to 3000°C (minus 40 to 5432°F), consists of six 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.

To meet the needs of a many industries and a wide range of applications, Raytek offers five types of MM sensors:

Model     Temperature Range     Spectral Response     Response Time

1MH 650°C to 3000°C
(1202°F to 5432°F) 1 µm 2 ms


All sensors feature identical installation hardware and include Raytek DataTemp Multidrop software to enable easy and consistent installation, configuration and data capture across the full breadth of an application:

o steel and metals processing (foundry/forging operations & heat treating)

o glass bending, forming, tempering, annealing, and sealing

o paper processing (ink drying/curing & lamination)

o plastics processing and thermoforming; and semiconductor processing
