Humidity Shock
Overview

Purpose & Application

The ENV-04-4 humidity shock chamber executes rapid transitions between defined humidity states (typically dry < 10% RH and humid > 90% RH) at controlled temperatures. Supplements thermal shock testing for HALT / HASS programmes and packaging qualification studies. Programmable cycle profiles satisfy custom and standard moisture stress procedures.
