Temperature humidity testing — RHS-B and RHS-F chambers for conditioning, damp heat and thermal cycling
50L-1000L, 0-60°C, 40-95% RH
Temperature humidity, stability and climate testing on one chamber platform
Environmental Chambers
An environmental chamber is an engineered enclosure that recreates a set of conditions — temperature, humidity, light — and holds them steady for as long as your study runs: hours, weeks or the full shelf-life of a pharmaceutical batch. What changes between families is which variables are controlled and how tightly. That one question — what must stay constant, and for how long — is how WSHLab organises its entire environmental test chamber range. Four families cover the workflow. Temperature humidity chambers hold 0–60°C and 40–95% RH for conditioning, damp heat and thermal cycling studies, in benchtop sizes from 50L up to a 1000L floor-standing cabinet. Pharmaceutical stability test chambers add ICH Q1A(Q2) compliance, 10–65°C and up to 60,000 lux photostability for accelerated and long-term studies to 1025L. Climate chambers combine temperature, humidity and LED top light for ecological simulation. Growth chambers bring adjustable LED full-spectrum lighting to plant growth and seed germination protocols. Every WSHLab environmental chamber is built in our ISO 9001 facility, CE certified, and shipped with a factory test report covering setpoint accuracy, uniformity mapping and alarm verification. Capacities run from 50L to 1025L. If you already know the chamber type, jump to a family below; if you are specifying your first controlled environment chamber, start with the selection guide — it follows the same decision sequence our application engineers use on a real procurement call.

TECHNICAL DATA
How every WSHLAB environmental chamber is engineered
One architecture across four families: a 304 stainless chamber with rounded corners, dual-wall insulation, a balanced refrigeration and humidification circuit, and a microcomputer or 7-inch touchscreen controller with self-tuning PID, program segments and over-temperature protection. The differences between families are the controlled variables — light, photostability, ICH profiles — not accidents of a single design.

PERFORMANCE & SELECTION
What is an environmental chamber?
An environmental chamber — also called an environmental test chamber, climate chamber or controlled environment chamber — is an insulated enclosure whose temperature, humidity and sometimes lighting are regulated by a PID controller reading calibrated sensors. Unlike a simple incubator it is designed around uniformity and stability: every point in the workspace stays within specification, not just the sensor location, and every excursion is recorded.
- An environmental test chamber controls two or more variables simultaneously
- Typical envelopes: 0–65°C and 40–95% RH, with LED or photostability lighting where required
- Touchscreen programmers run multi-segment thermal cycling and constant climate profiles
- USB and RS485 export turn the chamber's logged data into study documentation
CONFIGURATION & COMPATIBILITY
Types of environmental chambers: choose by what the study controls
The fastest route to the right chamber is to list the setpoints your protocol actually requires. Temperature and humidity — a temperature humidity chamber. Temperature and humidity to ICH Q1A(Q2) with photostability — a pharmaceutical stability chamber. Temperature, humidity and light for ecological work — a climate chamber or artificial climate cabinet. LED full-spectrum light for plants — a growth chamber. Each family shares the same controller platform, chamber finish and documentation set, so a laboratory can standardise across studies.
- Temperature humidity chamber — 0–60°C, 40–95% RH, conditioning and damp heat testing
- Stability test chamber — ICH Q1A(Q2), 10–65°C, photostability to 60,000 lux, GMP audit trail
- Climate chamber — combined temperature, humidity and LED top light simulation
- Growth chamber — LED full-spectrum lighting with adjustable intensity for plant protocols

QUESTIONS & ANSWERS
Environmental Chambers: frequently asked questions
The questions buyers ask most often when specifying Environmental Chambers, answered by our technical team.
What temperature range do WSHLAB environmental chambers cover?
RHS temperature humidity chambers cover 0–60°C, RAC climate chambers and GZX growth chambers cover 10–60°C, and RDS stability chambers cover 10–65°C. All families hold ±0.5°C uniformity across the working volume.
Do the chambers control humidity as well as temperature?
Yes. RHS and RDS chambers regulate 40–95% RH with ±3% uniformity; RAC climate chambers add programmable humidification; GZX growth chambers are temperature and light focused.
What sizes are available?
Benchtop chambers run 50L, 100L and 150L; floor-standing chambers run 250L to 1000L; stability chambers run 155L to 1025L. Most laboratories mix one benchtop unit for method development with a floor-standing unit for production studies.
Are the chambers ICH compliant?
RDS stability test chambers are designed and documented against ICH Q1A(Q2) for accelerated and long-term stability testing, including photostability testing up to 60,000 lux, and support GMP documentation requirements.
