The new PyroUSB 2.2 Series of infrared temperature sensors is ideal for
measuring the temperature of hot food products through glass containers.
After a food product is filled into glass jars, samples are usually taken from the
production line and manually probed to check the product temperature. The
PyroUSB 2.2 now makes it possible to check product temperatures without
taking samples from the production line, and without even touching the samples
Glass is highly transmissive to infrared radiation at wavelengths around 2.2
microns, so the PyroUSB 2.2 can effectively see though a glass container and
measure the temperature of the food product inside. Model PU151LT2.2 is
capable of measuring as low as 45°C.
