Description
Constant Temperature and Humidity Incubator, Program / Touch Screen Controller – China | CHI Series (80 L to 250 L)
CHI series constant temperature and humidity incubators combine refrigerated temperature control with precision humidity regulation for applications requiring simultaneous and stable climatic conditioning. The hidden thermal humidification system provides a wide humidity control range with minimal condensation risk, while the Honeywell humidity sensor ensures accurate and reliable humidity detection. Automatic water feeding maintains continuous, unattended operation without the need for manual refilling during extended test cycles.
The mirror stainless steel inner chamber and shelf are screw-free for hygiene and ease of sterilisation. A fluorescent lamp inside improves sample observation. The double evaporator switch defrost system ensures frost-free operation, and the special duct design maintains temperature uniformity within 1°C while preventing petri dishes from drying. Bottom casters allow easy unit relocation.
P-type models use a large-screen color LCD with 30-segment program control and digital temperature limiter. T-type models upgrade to a full touch screen interface with real-time temperature and humidity curve display, standard-included RS485 and USB port.
