Environmental Test Chamber (Temperature & Humidity)

Environmental Humidity Test Chamber

About Environmental Test Chamber

These Environmental Test Chambers with temperature and humidity adjustments are specially designed for creating atmosphere for conditions and testing of various products such as drug and medicinal products, tobacco and tobacco products, battery testing and testing of cement and electronic components etc. The basic use of an environmental chamber is to evaluate characteristics of products under variety of environmental conditions such as humidity and temperature.

PlusFurnace™ Environmental Chamber

Environment test chambers require customization to optimize performance and efficiency; therefore, under PlusFurnace™ brand, we have been manufacturing environmental test chambers to your specifications since 1978. These chambers are designed as floor standing large cabinets and walk-in room types. Our company, Exacta Furnaces has over 30 years of experience in test chamber designing and construction; therefore, we can meet your customization needs perfectly. No matter in what size or dimension you want to buy an environment chamber, we can construct the same unit at competitive price in India.


After discussing and consulting, we provide customized environmental test chamber design that incorporates the needs of the client. Once the specifications have been accepted, work begins and completed after successful installation and testing at client's site. From concept to construction, to testing and training, we are committed to utilizing the best components available. Only the latest and most efficient controllers, sensors, lights and switches in the industry are integrated into each environment chamber.


Our temperature and humidity test chambers provide dependable performance under economical price. Each humidity test machine is durably constructed with thick metallic sheets. Outer housing has high wear resistance and is made of good quality thick mild steel sheet which is powder coated and painted. Inner portion is made of 304 grades stainless steel which is corrosion resistant and also allows users to wipe and clean easily. The double walls are Polyurethane (PUF) insulated for superior temperature stability.


These humidity environment chambers provide temperature range between 5°C to 60°C. Temperature control is simple and done by electronic PID controller which shows set value and attained value, accuracy is excellent.


Unlike traditional environmental chambers, we have removed water pan for humidification. We use bottom for water reservoir, inlet and outlet pipes are connected at rear side of the machine. We can also make arrangement of lifting the lid and pour water directly into the reservoir. Our humidity chambers also meet ICH guidelines.


Cooling is achieved by cfc-free hermetically sealed ISI marked compressors. We use only known brand compressors for reliable stability.

Optional Accessories

- PLC & HMI interface
- RS232 / USB interface
- Electronic chart recorder
- Data logger
