Laboratory Equipment manufacturers, suppliers & exporters across continents. Offers a wide range of Scientific Products, Laboratory & Educational Equipment which includes Lab Stirrers, Magnetic Stirrers, Centrifuges, Shakers, Lab Refrigerators, Cooling Incubators, Humidity / Stability Chambers, Deep Freezers and Walk In Chambers.

Humidity and Temperature test chambers by Hema Scientific instruments are designed to provide such environment where highly accurate control of relative humidity and temperature is required. We manufacture humidity and test chamber in various sizes and temperature ranges; in addition, a number of optional accessories are fitted to enhance user experience. These systems are capable of delivering precise humidity and temperature control, while offering low maintenance requirements and built-in safety features for your operator. Depending upon requirements, we can design humidity chambers as cabinet type or large sized walk-in room type with complete on-site and off-site validation packages. All these units are supplied throughout India and overseas at factory price.


These equipment are designed for variety of applications and further constructed in benchtop and reach-in models with up to 3500 liters of capacity. From to basic to advanced temperature / humidity requirements, these environment chambers by Bionics Scientific are tailor made to exact needs.

Temperature / Humidity:

Designed with 3 different temperature ranges which can be further customized as required. These temperature ranges are ambient to 70°C. Humidity ranges from 20% to 98% RH with stability of + / – 3%. Temperature of heating and cooling functions is monitored and controlled by LCD / LED digital display with stability of + / – 5°C. All our humidity chambers are fitted with over temperature safety cut out.
