The new ESS301 sensor is made from Tekscan's new Enhanced Stability Series (ESS) pressure sensitive ink that allows for the same high quality performance as our other standard sensors, but with the added benefit of measuring force in a wider range of temperature and humidity. The ESS301 is capable of measuring force and pressure in environments with temperatures up to 85癈  and with a relative humidity up to 95%. This allows better performance in a wider range of operating and storage conditions.
