Climatic Chambers & Humidity Chambers in Singapore
A climatic chamber controls temperature and relative humidity inside a sealed test space, simulating storage and environmental conditions for stability, ageing, and reliability testing. Green Research Scientific supplies the Pol-Eko KK, KKP, and KKS climatic chamber range in Singapore, covering routine stability studies, high-temperature humidity testing, and photostability work, with steam and ultrasonic humidification options across capacities to 1,450 litres.
• Temperature 0 to +100 °C and humidity 10 to 90 % RH across the range
• ICH Q1A stability and Q1B photostability compliance
• Steam and ultrasonic humidification options
The Pol-Eko Climatic Chamber Range
Every Pol-Eko climatic chamber shares the same foundation, with acid-resistant stainless steel construction, forced air circulation, and SMART PRO touchscreen control as standard. The series differ in how they cool and humidify. The KK uses an ultrasonic humidifier for routine stability work, the KKS adds steam humidification for a wider temperature and humidity envelope, and the KKP replaces the compressor with Peltier elements for silent, refrigerant-free running.
KK Series — Ultrasonic Humidification Climatic Chambers
The entry point for stability and ageing studies within the 0 to +60 °C band. Lockable double doors secure running tests, and the ultrasonic humidifier holds 30 to 90 % RH across five chamber sizes. Suited to ICH Q1A long-term and accelerated storage conditions for pharmaceutical QC.
Spec block:
- Capacity 240 – 750 L
- Temperature 0 to +60 °C
- Humidity 30 to 90 % RH
- Lockable double doors
KKS Series — Steam Humidification Climatic Chambers
Available in +60 °C and +100 °C model variants, with steam humidification covering 10 to 90 % RH for electronics, plastics, and building-material test profiles. Open-door and parameter-exceedance alarms protect running studies, while Wi-Fi, LAN, and USB connectivity with LabDesk software enables remote monitoring and data download. Automatic NO FROST defrosting and transport castors come standard.
Spec block:
- Capacity 240 – 1,450 L
- Temperature 0 to +100 °C (model-dependent)
- Humidity 10 to 90 % RH
- Alarms, defrost, and remote monitoring as standard
KKP Series — Peltier-Cooled Climatic Chambers
Peltier elements heat and cool without a compressor, delivering the range's tightest temperature variation at the near-ambient setpoints where ICH Q1A stability studies run. The steam humidifier doses water through a peristaltic pump and heats only when humidity is called for, cutting energy draw in ECO mode. A phytotron configuration with FIT LED lighting is also available for this series.
Spec block:
- Peltier cooling, no refrigerant
- Steam humidifier with ECO mode
- ICH Q1A (R2) climate test points
- FIT LED phytotron variant available
Phytotron & Photostability Chambers
Phytotron configurations are the only Pol-Eko chambers controlling temperature, humidity, and lighting together, with FIT LED modules mounted above shelves, in side walls, or in doors, in cool white 4000K or a red, blue, and white growth spectrum. For pharmaceutical light-exposure testing, the KKS ICH photostability chamber completes a full ICH Q1B study in as little as 29 hours using dedicated UVA and VIS lamp systems rated at 1.2 million lux hours and 200 Wh/m² UV, with LabDesk CFR software for 21 CFR Part 11 compliant records.
Spec block:
- FIT LED lighting, four mounting configurations
- Day-night simulation with smooth intensity control
- KKS ICH: ICH Q1B compliant, UVA + VIS lighting
- LabDesk CFR software option

WHICH ONE FITS?
KK
For standard stability testing within 0 to +60 °C and 30 to 90 % RH, this is the most cost-effective option in the range.
KKS
For test profiles that need humidity below 30 % RH or temperatures up to +100 °C, such as electronics, plastics, and building materials testing.
KKP
For studies that run continuously for years near room temperature, such as ICH long-term stability programmes, where energy use and maintenance matter most.
Humidity Chamber, Climatic Chamber, or Stability Chamber?
The terms humidity chamber, climatic chamber, and stability chamber refer to the same class of equipment. All three describe a sealed test chamber maintaining programmable temperature and relative humidity conditions, and Green Research Scientific supplies the Pol-Eko range of these chambers to laboratories across Singapore.
Humidity Chamber
The common specification term when humidity control is the primary requirement, such as damp-heat testing of electronics, components, and packaging. The KK and KKS series above cover these applications.
Climatic Chamber
The manufacturer and catalogue term for the same equipment. Specifications and tender documents referencing climatic chambers are served by the Pol-Eko KK, KKS, and KKP series on this page.
Stability Chamber
The term used in pharmaceutical and cosmetics QC, where the chamber runs ICH shelf-life studies such as 40 °C at 75 % RH over six months. The KKP series is configured for these long-duration programmes.

Frequently Asked Questions
What is the difference between a humidity chamber and a stability chamber?
They are the same class of equipment. A humidity chamber is any chamber that controls temperature and relative humidity together, while a stability chamber is the name used when that chamber runs ICH shelf-life studies in pharmaceutical and cosmetics QC. Every Pol-Eko climatic chamber on this page performs both roles, with the KK, KKS, and KKP series covering the standard ICH Q1A storage conditions.
What is a climate chamber test?
A climate chamber test exposes a product or material to controlled temperature and humidity conditions to assess its durability, stability, or shelf life. Common examples include ICH Q1A stability studies for pharmaceuticals, 85/85 damp-heat screening of electronics, and accelerated ageing of plastics, coatings, and packaging.
What temperature and humidity ranges do climatic chambers cover?
The Pol-Eko climatic chamber range covers 0 to +60 °C with 30 to 90 % RH in the KK series, and extends to +100 °C with 10 to 90 % RH in the steam-humidified KKS series. The Peltier-cooled KKP series covers stability testing at near-ambient setpoints with the tightest temperature variation in the range.
What is the difference between a climatic chamber and a temperature chamber?
A temperature chamber controls temperature only. A climatic chamber adds active relative humidity control alongside temperature, which is required for any test where moisture drives the outcome, such as corrosion, damp-heat, and stability studies. If your test specifies an RH setpoint, you need a climatic chamber.
Do you provide installation and calibration support in Singapore?
Yes. Every chamber is installed and commissioned by Green Research Scientific’s in-house engineers in Singapore, with operator training included. Calibration, preventive maintenance, and repairs are handled locally with genuine Pol-Eko parts, so equipment is never shipped overseas for support.
