Noncontact sensor
The Marathon FR1 noncontact infrared sensor can be mounted in environments up to 200°C and connected to the electronics via fiberoptic cable. Three models cover 500°C to 2500°C, with accuracy to ±0.3% of value and a 10-ms response time. The sensor offers one- and two-color operation modes and meets NEMA 4 requirements.

Measuring microscope
The Model XAM-1 measuring microscope comes with a model TMCVS color LCD 4 x 2.5-in. monitor, 1/3 chip camera, and video adapter. The microscope frame moves on a precision dovetail slide, controlled by a knob on a digital micrometer that is programmable in inches or millimeters, in 0.00005-in. and 0.001-mm increments.
