Set the temperature. Hold it through the flash.
Vertical thermal chamber for the Nexun line. 15 to 75 °C, four PID-regulated zones, ±1.7 °C panel uniformity, eight PT100 acquisition channels, IV, temperature-coefficient and steady-state work on the same device.
Regular or steady-state.
Same chamber, two cooling-loop sizings. Pick by how the device under test is illuminated: briefly (pulsed simulator), or continuously (steady-state simulator).
Regular TC
For temperature-coefficient and pulsed-illumination work.
Pairs with any pulsed Nexun simulator (Pro Max, Pro, Evo). Sets the device under test to a target temperature, holds it through the flash, and steps through profiles for IEC-compliant temperature-coefficient measurement.
- ►Pulsed solar simulator measurements
- ►Temperature coefficient determination (IEC 60891)
- ►Reliable temperature control for standard characterization
- ►Brief or intermittent illumination scenarios
Steady-State TC
Engineered for steady-state operation under constant heat input.
Required when a steady-state light source is held on the device while temperature must be maintained, e.g., 25 °C reference conditions during long soaks. The cooling loop is sized to compensate for continuous absorbed irradiance.
- ►Pulsed simulator measurements (covers Regular TC duty)
- ►True steady-state operation at fixed temperature
- ►Pairs with Nexun Steady-State and Nexun Perovskite
- ►Compensates constant heat input from the light source
Four-zone PID. Eight-channel PT100. No reflections.
Three engineering details that make the difference between a temperature box and a measurement-grade thermal chamber.
Independent control across the active area.
Four electrical heaters, sixteen speed-controlled fans and four PT100 air sensors, one per zone, driven by a four-zone PID. Panel temperature uniformity stays within ±1.7 °C across the device.
Module-level temperature acquisition.
Eight PT100 channels with 4-point + GND shielded connection (RJ25), 1 s measurement rate and <±1 °C accuracy. Software calibration, USB 2.0 to the Nexun controller.
No back reflection into the simulator.
The chamber surface that faces the simulator uses a light-absorbing substrate, so secondary reflections don't compromise spectral or spatial measurement integrity. Vertical configuration on wheels, modular floor space.
Built for the labs that take temperature seriously.
- ►IEC 60891 temperature-coefficient determination on production and lab systems
- ►STC (25 °C) reference measurements during steady-state long-soak tests
- ►Perovskite preconditioning under controlled thermal envelopes
- ►Cell and module thermal stability characterisation across the 15–75 °C range
- ►Calibration laboratories needing repeatable thermal set-points with traceable PT100 chains
- ►Quality labs validating module performance at extreme operating temperatures
Every number, on the table.
