Overview

Purpose & Application

The ENV-02-1 chamber performs hot, cold and humidity steady-state testing across an extended temperature and humidity envelope. Plot A (20-80 degC, 15-98% RH) covers IS 9000, JSS 55555 and MIL-STD-810 procedures, while plot B (15-85 degC, 15-98% RH) extends the working envelope for low-temperature low-RH and high-temperature high-RH testing. Humidity is generated by low-pressure steam, with refrigeration-based dehumidification.
