Pyrometer high temperature

Raytek 3I PLUS infra red thermometer for high temperatures is a new model replacing the existing 3i series for short wavelength high temperature applications. It is stronger, has better specifications and a lower price than the earlier model and data logging up to 4900 data points. Measuring with shorter IR wavelengths provides more stable readings at medium to high temperatures and the reading is affected less by errors in setting the emissivity [or variable emissivity]
Higher optical resolution allows measurement from further away from the target, and a 1M drop resistance means the new 3I is less prone to physical damage.
The BLUETOOTH functions are not available in Australia until the RF is approved – please check if these are important to you.
