Advanced laser optics define infrared thermometer target area

Keywords Infrared, Lasers, Temperature

A new generation of portable IR thermometers from Raytek Corporation makes critical temperature measurements more reliable by defining the target area with a 16 point laser sighting circle (see Plate 2). Precise aiming, combined with enhanced electronic data storage and emissivity reference tables, improve the speed and accuracy of temperature measurements in a broad spectrum of process and maintenance applications throughout industry and institutions.

The new Raynger MX instruments are the only portable IR thermometers on the market with a laser circle that defines the target spot size and center at any measurement distance, reports the company. The series incorporates other advances which increase temperature data gathering capability, such as on-board emissivity references and temperature logging, a bar graph display of the last ten readings and contact probe inputs.

The three models comprising the battery powered MX Series have a measuring range of ­30 to 900°C, and a 60:1 distance to target area ratio. The MX2 is intended to meet basic temperature measuring needs, while the MX4 adds storage for 100 readings, scrollable emissivity data, and an RS232 digital output for computer communication.

The MX4+ version also includes Windows compatible graphing software, a line voltage power supply, a Type K thermocouple probe and an RS232 computer cable. These additional features are optionally available on the MX4, plus other accessories including a portable thermal printer, thermistor (NTC) probe and a calibration certificate.

Probe inputs allow users the option of simultaneously taking an infrared and contact measurement. This option is also useful when a non-contact measurement is not feasible or when the emitting property (emissivity) of measurement surfaces is unknown. Probe and IR readings are compared, and the IR thermometer emissivity is adjusted until both measurements match.
