Product details

1、 Product Overview

The ACM483T-A precision dew point meter is a device designed based on the principle of optical cold mirror, which directly measures temperature and humidity. Unlike the method of indirectly measuring humidity through changes in capacitance and resistance, the dew point meter using the optical cold mirror principle directly measures the humidity of the environment according to the dew point definition.

ACM483T-AAbandoning the traditional copper gold-plated mirror process,useMEMSSemiconductor technology,Innovative use of silicon platinum plating+Hydrophobic polymer material coating as a condensation mirror surface, making itHas corrosion resistance, high and low temperature resistanceLong term stability, reliability, and high measurement accuracyBy utilizing the same characteristics and innovating circuit design to achieve high-precision integration, this product is able toUsed in most application environments andTo meet the requirements of some harsh environments,Ensure high measurement accuracy.

ACM483T-AAdopting a 4-inch colorful capacitive touch screen interface display, its user-friendly human-computer interaction interface is easy to operate and handle. Users can directly observe the required parameter data and the curve graph of its changes over time. This dew point meter provides multiple parameter conversions suitable for different demand scenarios.In summary, the ACM483T-A precision dew point meter has the characteristics of high accuracy, stability, good repeatability, long service life, and simple operation interface.
