PHOENIX Instrument CH Series Climate Chamber
Specially developed for the food industry, textile and packaging sectors, and rubber and plastics technology, the PHOENIX Instrument CH Series Climate Chamber is a high-quality solution for demanding stability, ageing and environmental simulations. Precise temperature and humidity control allows for detailed material testing and ensures compliance with international standards. The combination of flexibly programmable functions, robust construction and a sophisticated safety concept sets this series apart from comparable climate chambers on the market.
Innovative technology for industrial and scientific precision
With powerful digital PID control, the CH series sets standards in the field of controlled environmental simulations. Precise temperature control enables repeatability for standardised long-term and rapid tests. Thanks to the standard mini printer, fully documented test reports are available - a significant advantage for GLP-compliant laboratories and all users who value auditable evidence.

Usable volume: Selectable 150 l (CH-150) or 250 l (CH-250) Temperature range: -10 °C to +85 °C (without humidity); +10 °C to +70 °C (with humidity control)
Humidity range: 45% to 95% RH adjustable Temperature accuracy: ±0.1 °C; homogeneity ±0.5 °C (dry) / ±1.5 °C (with humidity)
Safety class: 3.1, including double temperature limiter Stainless steel inner chamber with rounded corners & removable shelves Programme memory for 100 steps and continuous timer operation
Other technical features include stable interior lighting via LED, a generous viewing window and a practical side passage hole (25 mm), which allows easy insertion of sensors or other measuring equipment. The robust shelves (10 kg per shelf, expandable to 10/12 shelves depending on the model) ensure sufficient flexibility for a wide variety of sample sizes and quantities. Cleaning is particularly easy thanks to removable inserts and smooth stainless steel surfaces - a plus in terms of hygiene and cross-contamination prevention.
An external, generously dimensioned water tank ensures continuous and trouble-free humidity control. The system automatically warns when the water level is low, allowing uninterrupted long-term experiments to be carried out.
Certifications and international standards
The climate chambers in this series meet all current CE requirements and relevant DIN standards for laboratory and development operations. The option of complete documentation and precise traceability of test parameters makes the CH series ideal for GLP-certified laboratory processes and industrial quality assurance in accordance with international standards.
Typical areas of application in laboratories and industry
-
Food stability and shelf life testing: Simulated storage conditions enable precise shelf life testing of milk powder, chocolate products and preserved foods.
-
Textile & packaging analysis: Moisture, heat and alternating climate tests support the prediction of material ageing, for example in packaging cartons, papers or textile fibres under real climate conditions.
-
Polymer and plastics testing: Determination of embrittlement or hardening behaviour in polyethylene, silicones and elastomers - ideal for development and quality departments.
-
Research & development: Performing demanding material tests, validating sensors, developing new surface coatings and testing innovative adhesive systems.
FAQs on use and maintenance
How often does the external water tank need to be filled?
As a rule, filling the generously sized tank is sufficient for several extended test runs. The integrated level indicator provides timely information about low water levels.
How is the temperature in the test area reliably controlled?
A digital PID controller with two redundant safety systems ensures constant temperatures and prevents overheating that could damage products or samples.
Is regular calibration necessary?
For maximum precision, especially in QA-relevant applications in the pharmaceutical and food industries, the sensors should be professionally calibrated at least once a year.
How are sensitive samples protected from condensation moisture?
Thanks to an optimised door seal and precise humidity control, a high level of interior stability is ensured. Within permissible parameters, the risk of condensation forming is reduced to a minimum.
Summary of the most important advantages
The CH series stands for precise, flexibly programmable environmental simulation with excellent documentation and the highest safety standards. Its versatility in temperature and humidity management, convenient operation via modern control elements, generously dimensioned interior and excellent cleaning and service features make it the first choice for industrial testing, research projects and laboratory operations with advanced quality requirements. By investing in the CH series, companies ensure robust process reliability, standard-compliant documentation and sustainable operational efficiency.
