Company information
For temperature, humidity (dew point), and pressure control and measurement, trust Daiichi Science. ■ About Moisture Control We respond to various requirements, from compact low-flow specifications suitable for small spaces that easily supply moisture through gas media to analytical and testing equipment, to large-flow specifications that can accommodate calibration and inspection agencies as well as sensor device development and manufacturing lines. Additionally, we manufacture precision chambers with minimal temperature distribution, allowing for precise control of moisture at sub-zero temperatures and systems that measure the adsorption and desorption of samples, all without causing condensation (though condensation can also be achieved if desired). With our patented ultra-stable saturation tank and heating function, we enable high-precision, non-condensation control, and the automatic water supply function allows for long-term operation, supporting programmed operation as well. ■ About Temperature and Humidity (Dew Point) Measurement ◎ Hygrometers We sell Rotronic hygrometers that can measure a wide range from -100 to 200°C with high precision of ±0.8% rh (at 10 to 30°C). *We are the domestic distributor for Rotronic. ◎ Dew Point Meters We sell mirror-cooled dew point meters capable of measuring a wide range of -40 to +90°C dp with just one unit (in stock).
