Thermostatic test chamber F-TH series

climatichumiditytemperature

Overview
Fast temperature change rate test chambers simulate rapid temperature transitions for accelerated environmental testing. Designed with enhanced airflow and larger compressors, F-TH series supports rapid ramps for qualification, accelerated stress screening and HALT-style procedures. Linear and nonlinear control modes are available; humidity control is optional.

Configurations

• Linear Mode: 3–20 °C/min with full linear control — adjustable constant slope for repeatable, comparable qualification cycles.
• Nonlinear Mode: 3–30 °C/min with variable ramp profile — faster peak rates for accelerated stress screening; humidity can be combined.

Features — What This System Delivers

• Speed: Practical linear ramps up to 20 °C/min to reduce test time while preserving profile consistency.
• Coverage: Wide temperature span (−70 °C to +150 °C) with optional humidity control (20%–98% R.H.; 10%–98% or 5%–98% with dehumidifier).
• Accuracy & uniformity: ±0.5 °C control accuracy; ±2.0 °C distribution uniformity.
• Flexibility: Four standard internal volumes and multiple option levels (A~F) for tailored configurations.

Built-in Functions

• BTHC temperature & humidity control with PID + SSR and auto-calculation.
• Programmable multi-segment cycling: up to 100 programs, 100 segments per program; max 999 cycles per program.
