Thermostatic test chamber F-TH series

climatichumiditytemperature

Overview
High stress of 5C/min ~ 15C/min. This faster temperature (and optional humidity) chamber enables the application of high stress to the specimen at a rapid temperature change rate of 5 °C/min or more. Due to the larger refrigeration system, 5 °C/min or more is achieved from -45 °C to +155 °C with the F-TH and F-HL models (with or without specimen loaded). Instrumentation is integrated into the door. The controller unit is a bright color LCD interactive touch-screen system which provides easy controlling of the chamber.

Control modes & configuration

• Linear Mode: 3–20 °C/min with full linear control — constant ramp rate from start to finish; adjustable and repeatable for standards-compliant tests.
• Nonlinear Mode: 3–30 °C/min with faster peak ramp — ramp varies across the profile for accelerated stress screening; humidity function can be combined.

Key features

• Up to 20 °C/min linear ramp (practical high-speed linear control).
• Temperature control with optional humidity (20%–98% R.H.; extended ranges with dehumidifier).
• Control accuracy: ±0.5 °C and humidity control ±2.5% R.H.
• Built-in BTHC temperature & humidity control with P.I.D. + S.S.R. and auto-calculate function.
• Programmable multi-segment cycling: up to 100 programs × 100 segments; up to 999 cycles per program.
• Power-off memory with multi-year backup; imported LCD display showing set/actual/time.
• Dual refrigeration loop with imported, fully-closed compressors for fast cooling (air-cooled or water-cooled).
• Standard DIN PT-100Ω sensor for stable long-term temperature measurement.
• Interfaces: RS-232 / RS-485 and timer relay output; interface lock and alarm functions.
