Comprehensive Range of Environmental Test Chambers
For every testing requirement, NVIRO Solutions offers an appropriate chamber or system. Our environmental test equipment range includes:
HAST Chambers (Highly Accelerated Stress Test)
Specialized chambers for accelerated humidity and pressure testing, ideal for rapidly aging electronic components under highly accelerated stress conditions (up to 105°C, 85% RH, 3–4 atm pressure). HAST chambers help reveal latent defects in semiconductor devices and circuit boards much faster than traditional methods.Thermal Shock Chambers
Two-zone or three-zone chambers that cycle products between extreme hot and cold temperatures in seconds. These chambers expose materials to rapid temperature changes, identifying failures due to thermal expansion, contraction, and stress. Thermal shock chambers are crucial for industries like aerospace and automotive to ensure parts survive sudden temperature swings.Temperature & Humidity Chambers
Precision climate chambers for controlling temperature and humidity over a wide range. These temperature humidity chambers maintain steady-state or cycling conditions (e.g. -70°C to +180°C, 10% to 98% RH) to test product performance in various climatic environments. They are used for electronics burn-in, stability testing of materials, and more.Salt Fog & Corrosion Test Chambers
Equipment for simulating corrosive environments (salt spray/fog, cyclic corrosion) according to standards like ASTM B117. Our salt fog testing equipment creates a fine mist of salt solution to evaluate coating durability and corrosion resistance of metals, paints, and finishes. These chambers help predict how products will withstand marine or coastal conditions.Walk-In & Drive-In Chambers, Walk-in chambers and drive-in chambers
For testing large products, assemblies, or even vehicles. We build room-size chambers that a person (or vehicle) can enter, with custom dimensions and features. These large-scale solutions are used for automotive testing (even full cars), aerospace components, battery packs, and other big installations. They often integrate multiple stressors (temperature, humidity, vibration, etc.) in one environment.
Note: Many of our standard models can be further customized or combined (e.g. adding vibration tables, altitude simulation, or custom data acquisition) to meet unique testing needs. If you don’t see a chamber that fits your exact requirements, our team can design a custom environmental test chamber from the ground up.

Rain & Salt Fog Test Chamber update
Hastest Solutions Inc has recently manufactured their customized Rain & Salt Fog Test Chamber built according to MIL-STD 810G and ASTM B117 for the US Navy. This test chamber measures 40 feet in width, 20 feet in height and 15 feet in depth. Hastest Solutions Inc continues its efforts to
What is Salt Spray Testing?
A Salt Spray Test is an accelerated laboratory test providing a controlled corrosive environment to determine the rusting performance of a product in the field. Salt Spray Testing is a requirement in a wide range of industries such as automotive, military, paint, and research institutions. It can be conducted on
What is HAST Testing?
In effort to improve the reliability of products, many different industries, just to mention a few, including semiconductor, pharmaceutical, LED and solar companies turn to HAST testing as a shorter alternative to THB Testing. The acronym “HAST” stands for “Highly Accelerated Temperature/Humidity Stress Test.” The acronym “THB” stands for “Temperature
Custom Solutions & Engineering Support
At NVIRO Solutions, we pride ourselves on building custom test chambers tailored to client specifications. Our engineering team will work with you to design chambers with the exact size, performance range, and features you need. Whether it’s modifying an existing design or creating a completely new system, we provide end-to-end support, from initial concept and 3D modeling to fabrication, installation, and on-site calibration.
We have delivered numerous one-of-a-kind solutions. For example, we developed a massive 40 ft × 20 ft × 15 ft blowing rain and salt fog test chamber for a U.S. Navy project, built to MIL-STD-810G and ASTM B117 standards. This custom walk-in chamber can simulate intense rain and corrosive salt fog conditions, and is one of the largest of its kind. No challenge is too big: whether you need an ultra-fast temperature cycling chamber, a combined environment (temperature/humidity/vibration) system, or an extra-large drive-in facility, our experts are ready to create a solution.
Throughout the design process, our engineers ensure that each chamber meets all relevant industry standards and test protocols. We can incorporate compliance with MIL-STD (military standards for environmental testing), JEDEC (for electronics), IEC/ISO guidelines, and any other specific standards you require. Every custom chamber undergoes rigorous quality checks and performance validation before delivery.
Frequently Asked Questions
An environmental test chamber is a specialized enclosure used to simulate various environmental conditions (such as temperature extremes, humidity, thermal shock, corrosion, vibration, etc.) in a controlled setting. By placing products or materials inside a test chamber, engineers can expose them to harsh conditions and observe how they perform. Environmental test chambers are crucial for reliability testing – they help predict a product’s lifespan, identify design weaknesses, and ensure that items will function correctly under expected (or extreme) operating conditions. These chambers come in many types and sizes, from small benchtop units to walk-in rooms, depending on the application.
A HAST chamber (Highly Accelerated Stress Test chamber) is a type of environmental test chamber designed to speed up humidity-induced stress on electronic components. HAST chambers create high-temperature, high-humidity, high-pressure conditions to accelerate the aging process of devices. For example, a HAST test might run at 110°C, 85% relative humidity, and 2 atmospheres of pressure to induce failure mechanisms in ICs, circuit boards, or other components much faster than normal life testing. This helps manufacturers uncover latent defects like corrosion, insulation degradation, or seal failures in days instead of months. HAST is often used as an alternative to traditional longer-duration humidity or soak tests, especially in the semiconductor and electronics industry, to ensure product reliability under harsh conditions.
