Temperature chambers

For tests in a temperature range of -80°C to +250°C

All system components of these temperature chambers "Made by Zwick/Roell" work together perfectly for your testing needs. All system functions feature convenient, intuitive operation via the Zwick testing software. All data can be documented traceably with the test series. The temperature chambers are perfectly compatible with Zwick’s extension measurement system. Reliable test results are guaranteed for both optical and contact measurements. The modular concept allows optimum adaptation of the chamber to suit your needs. The large chamber volume allows additional test area space for components testing.

Key Advantages and Features

Reliable test results

The chambers feature very low vibration, allowing optimum integration of the temperature chamber with Zwick extensometry. Reliable test results are guaranteed, regardless of whether optical or contact-type measurement is used.

Exact temperature control

The sophisticated air-feed system ensures extremely uniform temperature distribution. Precision control guarantees stable temperatures with no overshooting, while pre-configured control parameters ensure the temperature is attained quickly and precisely. In conjunction with the Zwick System Configuration Builder, specimen-specific control parameters can easily be loaded with the test program. The optional close-proximity temperature sensor enables temperature control at the critical sensor location, for optimum test results. The practical holder allows the sensor to be positioned quickly and precisely. Completely uniform, extremely accurate temperature control (+/- 1°C) ensures that your specimen is always at exactly the right temperature.

Maximum operating convenience

All system functions feature convenient, intuitive operation via the Zwick testing software. The control layout adapts interactively to the test sequence and provides direct feedback. You can access all the data from your test series whenever you require. Zwick's testing software allows the temperature chamber fan speed to be conveniently adjusted, ensuring reliable test results even with sensitive specimens such as films. The optional safety door function guarantees operator protection in accordance with European safety regulations, with the chamber door acting as a safety door with guard locking.

Flexible in use

The modular concept allows optimum adaptation of the chamber to suit your needs. The large chamber volume provides additional test area space for component testing and a constant temperature in the area around the specimen. Future-proof: if you need to extend the range of application, all options can be retrofitted on-site as required.

Perfect extensometer integration

These low-vibration temperature chambers provide optimum operating conditions for all extensometers. Extensometers are mounted at left rear, ensuring an unobstructed view into the test area through the window. To simplify installation a mechanical T-slotted module is available for sensor arms, together with an optical glass module for non-contact extensometers. This enables all extensometers available from Zwick to be used with the temperature chambers.

Cost and time savings

  • The following features guarantee short cycle times free from lengthy heating periods, offering maximum savings.
  • Temperature-condition your specimens in the magazine.
  • Change specimens through the optional small chamber-door opening and benefit from minimal temperature changes and greatly reduced ice formation.
  • Use the special insertion aid to center your specimens quickly and precisely.

Applications and technical overview

Applications

The temperature chamber and its accessories have been designed especially for use in Zwick materials testing machines.
Tests at exact controlled temperatures, ambient or specimen temperature, can be carried out. The temperature chamber is suitable for running tests in that temperature range subject to the values stated in the technical data for:

  • Plastics testing: reliable test results, e.g. to ISO 527-1, ASTM D638
  • Rubber, elastomers: standard-compliant tests plus temperature accuracy, e.g. to ISO 23529 and ISO 37
  • Composites: tests using a wide range of fixtures
