ADDITIONAL ONBOARD INSTRUMENTATION

CONTROLLER:

WATLOW F4T PROGRAMMABLE CONTROLLER. Features a 4.3" capacitive touchscreen, minimizing the chance for error. Ethernet communication supported by AESONE CONNECT®. View controller options

SENSORS:

• RTD — 100 OHM PLATINUM: Measured at the point of airflow entering the workspace. Class A, 3-wire platinum resistance sensor. Standard on all chambers.
• VAISALA HMM100 RELATIVE HUMIDITY SENSOR: Measured at the point of airflow entering the workspace. Airflow speed does not affect measurement. Highly accurate between 10–95% RH over the entire operating range of −70°C to +180°C (−94°F to +356°F). (Optional)
• TYPE T THERMOCOUPLE: Connects to the limit controller for safety monitoring. (Additional Purchase)
• HIGH HUMIDITY HEATED SENSOR: Replaces the standard RH sensor and enables testing up to 98% RH. The heated probe prevents condensation and maintains accuracy across high humidity, vacuum, and pressurized environments. (Upgrade Available)

PERFORMANCE, CYCLING WALK-IN TEST CHAMBERS

Performance test chambers are used for iterative testing where conditions fluctuate. 

Chambers are available in more than two dozen sizes and can be combined with many power packages.  Below is a small sampling of our most common chamber sizes with associated power packages to help you understand the performance options available to you.  The matrix allows you to choose by size or by performance needs.

*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.

*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.
