R718CKAB Wireless Type K Thermocouple and Temperature/Humidity Sensor

The temperature/humidity sensor and K-type thermocouple can respectively detect the temperature and humidity, and an object's surface temperature. The temperature measurement range of R718CKAB is -40 °C to +375°C. R718CKAB has the features of good linearity, larger thermal electromotive force, high sensitivity and stability. It should not be used in sulfuric environments, reducing, oxidizing, and vacuum atmospheres, or weak oxidizing atmosphere.
