Description
Overview
The RAC series is WSHLab’s artificial climate chamber: temperature, humidity and light on one microcomputer controller, so a climate is reproduced rather than a single setpoint. Programmes hold constant climate states — 25°C/70% RH under continuous light, for example — or step through diurnal cycles with temperature, humidity and the LED top light moving together.
Two benchtop capacities, 150L and 250L, carry the workload. Both use a 304 stainless chamber behind a tempered glass door window, so the study is observed without breaking the climate, and adjustable shelving takes trays, cages or sample boards. Ultrasonic humidification holds the dew point the profile demands, and the refrigeration circuit covers 10–60°C.
Ecological simulation, insect rearing under defined photoperiods, seed and plant preconditioning, materials behaviour under cycling light and humidity — wherever a study needs three variables documented together, the RAC cabinet is the benchtop instrument.
Key features
- Three variables, one controller. 10–60°C temperature, programmable humidity and LED top light combined in repeating climate profiles
- LED top light. programmable on/off cycles with uniform illumination at the sample plane for day/night simulation
- Tempered glass window. observe the study through the door without breaking the climate state
- 304 stainless chamber. rounded corners wipe clean between studies; adjustable shelving for trays, cages and boards
- Programmable diurnal profiles. constant climate states or day/night cycles with temperature, humidity and light stepping together
- Microcomputer PID control. self-tuning loops hold temperature and humidity through load and door events

Frequently asked questions
What sizes are available?
150L and 250L benchtop capacities, both with the 304 stainless chamber and tempered glass window.
What light does it provide?
An LED top light with programmable on/off cycles, positioned for uniform illumination at the sample plane.
What is the temperature range?
10–60°C under microcomputer PID control.
Does it control humidity?
Yes — programmable ultrasonic humidification holds constant or cycled humidity states on the same controller as temperature and light.
