The RAY-30 Infrared Oil Meter can be used to record either IR absorption or (with accessories) IR reflection spectra in the range of 4000 cm-1 to 400 cm-1 (wavelengths from 2.5 um to 25um). The user can do
qualitative or quantitativeanalysis on the measured sample using either the stored spectrum or the plotted
spectrum. It is a useful tool for petrology, the chemical industry, medical work, food,safety, the paper industry, environmental monitoring, the semiconductor industry, etc.,for material structure analysis.

Metal Convection Heater

The metal Convection heater warm the room as it passes over a heated coil; some use a fan to forced in the cool air to heat. The heated air rises naturally or is forced out by a fan and spreads into the space to warm room.

A metal convection heater is a type of heater that uses convection currents to heat and circulate air. These currents circulate throughout the body of the appliance and across its heating element.

Convector Heater including glass convection heater, metal convection heater, also mini convector heater can be a Frost Heater.
