Thermostatic test chamber TH series

climatichumiditytemperature

Overview
This programmable temperature and humidity test chamber (environmental test machine) is engineered for textile conditioning and testing in accordance with ISO 139 and ASTM D1776. It provides controlled temperature and humidity profiles for evaluating material and product tolerance to heat, cold, dry and humid conditions. Standard models and custom sizes are available across the TH series to suit laboratory, QA and production test needs.
