We are currently offering a free copy of "Basic Knowledge of Temperature Vol. 1: What is a Heat Bridge?" which summarizes our company's know-how and insights related to devices that handle humidity, temperature, dew point, and pressure! This document explains the mechanism of heat bridges and offers tips for understanding accurate temperature. It also clearly introduces a thin constant temperature and humidity chamber that enables control of temperature and humidity in a space as small as 1mm, using diagrams for better understanding. 【Recommended for】 ■ Those involved in research and development related to temperature ■ Those facing issues (challenges) concerning temperature ■ Those who want to review basic knowledge of temperature ■ Those who want to help newcomers acquire practical knowledge, etc. *For more details, please refer to the PDF document or feel free to contact us.

We believe that dew point measurement is fundamental to atmosphere control in gas carburizing heat treatment. With the increasing momentum for the introduction of ISO 9000 in quality management at carburizing heat treatment sites, we recommend the adoption of mirror-cooled dew point meters and the establishment of a quality management system based on this. We are pleased to present a technical report summarizing our know-how and insights on humidity, temperature, dew point, and pressure: "Introduction to the Management of Gas Carburizing Heat Treatment Atmospheres Using Mirror-Cooled Dew Point Meters." [Contents] ■ Surface hardening methods for steel parts ■ Gas carburizing ■ Dew point measurement of carburizing atmospheres ■ ISO 9000/QS 9000 and dew point measurement ■ Recommendation for the introduction of mirror-cooled dew point meters *For more details, please refer to the PDF document or feel free to contact us.
