Product Introduction
ACT-102 Digital Temperature Transmitter is a combination with the technical characteristics of conventional transmitter and built-in spare battery, so that it can still measure the temperature in case of external power off. Its imported advanced temperature sensor ensures a high performance, long service life, high precision, a long term stability and less maintenance . It can be extended with various kinds of interface when it outputs standard analogue signals. The instrument has a backlight function, clear night readings. It is widely used in the field temperature measurement. It has become a substitute product to the traditional common temperature transmitter.
