Coronavirus Update  --- Hands Free Temperature Screening

Thermographic's Promotional Packaged Feverscan®  forehead thermometers were successfully used worldwide during the SARS epidemic to check for fevers in schools, offices, homes and at airports. LCR Hallcrest’s forehead fever thermometers are again in high demand.

Made in the USA, in a FDA registered ISO13485 certified facility suitable for adults and children, these fever thermometers are quick and easy to use. Simply place, or have the patient affix one against a person’s forehead and read the thermometer scale after 15 seconds.  Symptoms of this new Coronavirus include fever and coughing with an incubation period, before symptoms appear, of 2 to 14 days after exposure.

LCR Hallcrest Thermochromic Inks change color in response to changes in temperature. Activation temperature points range from low refrigeration type temperatures through normal body temperatures to high temperatures that exceed the pain threshold. Touch Activated Liquid Crystal Ink will change color within the visible spectrum when rubbed or touched.

LCR Hallcrest Photochromic Inks change color when exposed to ultraviolet light, usually from the sun or a black light. The inks are effectively colorless indoors and turn into vibrant color outdoors. When brought back inside, the inks become clear again. The inks become intensely colored after only 15 seconds in direct sunshine and return to clear after about 5 minutes indoors.

Liquid Crystal for Science

Thermochromic Liquid Crystals (LC’s) are optically active mixtures of organic chemicals that can be highly temperature sensitive and change to many colors. LC’s start black below their temperature range, go through the colors of a rainbow and then black again above the temperature range. LC’s are reversible so they can be used repeatedly. The main application areas are in flow visualization and heat transfer studies, although the materials can be used in virtually any work involving indication of temperature fields and thermal mapping.


Thermochromic Test Kits 

Educational Materials

Test thermochromic color change effects with these exciting thermal and/ or UV activated color change water based screen paint kits and ready to use labels. Paints can be brushed or stamped on a substrate and cleaned up with water. Mix with acrylic paint to create stunning visual effects. Color change stickers are available in several colors, require no mixing and are easy to apply.
