Full Product Specification
| Temperature Scale | ºC or ºF - user selectable |
| Resolution | 1ºC or 1ºF (or 0.1ºC or 0.1ºF) - user selectable |
| Inputs | K-type thermocouples |
| Measurement Range | -50ºC to 1,300ºC (-58ºF to 2,000ºF) |
| Meter Operating Range | For use in 0ºC to 50ºC environment |
| Accuracy (18ºC to 28ºC ambient) |
±(0.3% of reading + 1ºC) -50ºC to 1,000ºC |
| ±(0.5% of reading + 1ºC) 1,000ºC to 1,300ºC | |
| ±(0.3% of reading + 2ºF) -58ºC to 2,000ºC | |
| The accuracy specification does not include type-K thermocouple probe accuracy | |
| Temperature Coefficient | 0.1 times the applicable accuracy specification per ºC from 0ºC to 18ºC and 28ºC to 50ºC |
| Error Offset | Errors contributed by one particular thermocouple may be practically eliminated, over a limited measurement range, using a recessed front panel OFF-SET adjustment on the meter and an accurate temperature standard when making the adjustment. Although making that adjustment may increase measurement errors made using other thermocouples. |

SYSTEM 4 thermometers offer exceptional flexibility with a choice of single wavelength, ratio, fibroptic and fibroptic ratio models. Thermometer type, temperature range, spectral response and optical characteristics are chosen to suit any application from 0 to 2600ºC.
FEATURES
Portable Infrared Thermometer
The Cyclops 100 is a general purpose, high precision, portable infrared thermometer, designed for accurate measurement of temperatures in the range 550 to 3000ºC (1022 to 5432ºF).
The measured temperature is displayed in four simultaneous modes: continuous, peak, mean and valley, with user selected mode for the viewfinder display.
Accurate sighting is ensured by the clear, wide angle (9º) field of view and small, clearly defined (1/3º) measurement area. Focusing is variable from 1m to infinity, with close focus options available using auxilliary lenses.
