Hand-held FIT power meters (up to 500W)

FIT laser power sensors work on the principle of a patented technique for measuring temperature dynamics with a broadband thermocouple. As a result, measurement and data collection are fully automated.

A total of 3 models cover power measurements from 500 mW to 500 W.

The innovative measurement concept reduces the measurement and display time of laser power in less than 4 s with perfect repeatability (± 1%), accuracy (± 3%) and high resolution (± 60 mW up to 50W) combined with a wide range of measurable powers.


The probes of the FIT series have a multifunctional LCD display, which simultaneously shows the measured laser power, the selected laser wavelength (wavelengths of CO2 and NdYAG lasers are standard, but at the customer’s request, the probes can be calibrated to other wavelengths). The display also warns that the battery is low. The temperature bar shows the current sensor temperature (if the operating temperature of the sensor is exceeded, it is necessary to end the measurement and wait until the temperature drops)

All sensors are equipped with a broadband surface layer with low reflection and a high threshold of destruction.

Recalibration can be performed by user-electronic resetting of the original sensitivity value. Quality AA batteries can withstand at least 4000 measurements

FIT probes are accurate, easy to use and significantly cheaper than any other laser power meters with comparable parameters.

Thermal sensors have a faster response than thermoelectric ones. They have a higher wavelength range than silicon detectors. Thermal sensors do not degrade over time, and if not used properly, they can work for many years with the same parameters. The absorbers used guarantee the same absorption of laser radiation at all times.
