climatichumiditytemperature

Overview
Precise environmental simulation for reproducible laboratory and industrial testing. The CT300EC75 from Memmert provides a controlled climate environment with wide temperature and humidity ranges suitable for material tests, component qualification and accelerated aging studies.

Range of functions

• Adjustable parameters: temperature, relative humidity
• Device functions: climate regulation, real-time process display, program execution, alarm configuration
• Control: touch screen controller
• Interfaces: Ethernet LAN for data communication and remote monitoring

Temperature
Setting range: -75 to +180 °C. Cooling: optional or standard water-cooled condensers on -75 °C models. Heating: stainless-steel electric heaters in the air treatment tunnel. Stability: temperature fluctuations typically ±0.1 to ±0.3 K. Setting resolution: 0.1 °C.

Humidity
Setting range: 10 to 98 %rh. Humidification/drying via thermostatic bath with dew point control and additional dry coil for controlled dehumidification. Accuracy: 0.1 %rh.

Safety
Equipped with safety thermostat (over/under temperature limits) with automatic shutdown of thermal systems. Sensors: Pt100 DIN class A sensors (fixed and movable for flexible placement) and capacitive humidity sensor. Automatic stop and controller alarms for water failure, high/low humidity and high/low temperature events.

Standard equipment
Standard features include left entry port Ø 80 mm, water-cooled condenser (standard on -75 and -40 °C models), mechanical door lock, double silicone door gaskets and heated anti-condensation door frames. Optional accessories: water conductivity meter, documentation package.
