*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.

Notice for Customers Requesting R449A:
Consult our sales team regarding the use of R449A refrigerant (where applicable). This substitution ensures compliance with relevant regulations. Please be aware that the use of R449A will change the achievable low temperature to -35°C. Our sales team can provide detailed information regarding this change for your specific application.

STANDARD INSTRUMENTATION

CONTROLLER   

HD Series Test Chambers have incorporated AESONE CONNECT creating a robust connected device for a standard and uniform interface making test chamber operation easier.

AESONE XCHANGE is hardware internal to the chamber that increases your functionality

• Connects the test chamber controller to your network for increased accessibility
• On-board multi-year data logging

AESONE SOFTWARE gives you the power to

• Remote chamber operation and monitoring, 
• Web-based test profile creation, 
• Viewing current data and historical data visually
• Secure multi-level user access 

ADDITIONAL ONBOARD INSTRUMENTATION

WATLOW F4T PROGRAMMABLE CONTROLLER. Features a 4.3” capacitive touchscreen minimizing the chance for error and the low voltage PLC is touch-safe. Ethernet communication supported by AESONE HARDWARE. View more controller options

AIRFLOW. Variable frequency drive allows you to lower air velocity to meet your test requirements and reduce noise.

SENSORS.

• TEMPERATURE SENSOR. Measured at the point of airflow entering the workspace. Class A, 3-wire, 100 Ohm Platinum RTD sensor
• RELATIVE HUMIDITY SENSOR. Measured at the point of airflow entering the workspace. Speed of airflow does not affect measurement. Sensor is highly accurate between 10-95% RH, over the entire temperature operating range of -40°C to +180°C (-40°F to +356°F)
• View sensor options

OPTIONAL DATA LOGGERS. View additional data loggers

STANDARD SAFETY FEATURES
