Product Introduction
The dew point transmitter DMT152 is designed to measure low dew points, even as low as -80 ° C. Polymer sensor technology has created excellent performance stability and reliability for this transmitter. Widely used in fields such as air separation, plastic drying machines, drying chambers, drying gases, and high-voltage circuit breakers, as well as in environments and equipment. The structural design of the transmitter can prevent dust, dirt, and water splashes, and can be used in harsh environments. In harsh conditions, such as the combined effects of low humidity and high air temperature, the measurement results are also accurate and reliable. It has good anti condensation stability and durability, thus requiring less maintenance work.
