Humidity Steady
Overview

Purpose & Application

The ENV-03-1 humidity steady-state chamber controls relative humidity from 15% to 98% across the 15-85 degC envelope. Plot A (20-80 degC) covers IS 9000, JSS 55555 and MIL-STD-810; plot B extends to 15-85 degC for low-RH and high-RH conditions. Low-pressure steam humidification with refrigeration-based dehumidification provides stable, repeatable conditions.
