Chambers with superior temperature change performance

The AR Series chambers provide high levels of performance with a wide temperature and humidity control range. When a product or specimen is tested, it can generate heat & moisture. In this instance the chambers will automatically adjust to maintain the correct test parameters, changing temperature and humidity as required.

There are thirty two chambers in the AR series line-up providing a temperature change rate from 4K/minute to 18K/minute, conforming to IEC test standards for automotive parts.

All the Espec AR chambers feature Espec’s latest control instrumentation delivering high speed processing, plus built in Ethernet for fast and effective remote monitoring.

  • High-Accuracy Temperature & Humidity Control
  • Energy Saving Controls

Reduced temperature and humidity stabliisation time 

Temperature and humidity stabilisation time have been greatly reduced by minimising fluctuation as the chamber approaches set-point (under testing operation from room temperature to 85°C/85% rh).

The AR  series chambers use a specimen temperature control sensor to monitor and control the temperature of the object under test and the uniform temperature distribution minimises variations in test results & provides accurate testing.

Save Energy with the Eco-Operation Function 

The New eco-operation function can reduce power consumption during temperature and humidity tests at 85°C/85% RH by up to 85% compared to conventional operation.

  • Compatible with existing products – by changing software.
  • Compatible with AR Series
    *Not compatible with rapid-rate temperature cycle type ARGF/ARSF Series 

Remote monitoring and control via an advanced web application

No software is required to remotely monitor the cabinets. An innovative web browser application allows monitoring and control of the chamber with a Mobile PC, tablet, or smart phone using the chambers standard Ethernet/LAN port. multiple chamber connections are possible using the wireless connection, so control is never lost.

Email alert
When an alarm is triggered, an e-mail is sent to the registered PC or mobile address. A notification can also be sent at the time of test completion.

Copy your test programs, output data on USB memory
Without the need of a PC, copy and transfer your test profiles from one chamber to another. You can also download temperature and humidity data from the chamber for editing on your PC.
