HOW TO CHOOSE THE RIGHT TEMPERATURE AND HUMIDITY TEST CHAMBER? 5 KEY FACTORS YOU MUST KNOW
Choosing the right temperature and humidity test chamber can be confusing. Common questions include:
- "What range do I really need?"
- "How accurate does the control system need to be?"
- "Will this chamber support my product tests properly?"
This guide will help you make the right decision without overpaying. Whether you're testing electronics, automotive parts, or pharmaceuticals, remember: the best chamber is not the most expensive, but the one that fits your real needs.
1. KNOW YOUR INDUSTRY STANDARDS & TEST REQUIREMENTS
Each industry follows specific testing protocols. For example:
Automotive Parts: -40°C to +100°C, humidity from 10%RH to 95%RH
Battery Testing: Often requires extreme temperatures and safety features
Pharmaceutical Packaging: Demands stable humidity and long-term consistency
Electronics/Chips: Focus on temperature change rate and uniformity
TIP: Make sure your tests comply with ISO, IEC, GB, MIL, or other relevant standards.
2. TEMPERATURE & HUMIDITY RANGE
Define your minimum/maximum temperature and humidity needs, plus change rate.
| Parameter | Common Specs |
|---|---|
| Temp Range | -40°C to +150°C (some up to -70°C or +180°C) |
| Humidity Range | 20~98%RH (some down to 10%RH) |
| Temp Change Rate | Recommended ≥ 3°C/min for rapid test needs |
NOTE: Don’t overestimate your needs. Bigger ranges mean higher cost and power consumption.
3. INTERNAL SIZE & SAMPLE LOADING
- Leave at least 30% extra space for airflow and temperature/humidity balance.
- Heavy or large samples? Check loading capacity and shelf design.
- Plan the layout if testing multiple samples to avoid uneven conditions.
TIP: Ask the manufacturer to help check if the size suits your samples.
4. CONTROLLER SYSTEM & DATA LOGGING
Modern chambers offer smart control features. Things to consider:
Controller Brand: Japan UNICON, RKC, or custom system
Data Export: USB, SD card, or Ethernet support; Excel compatibility
Remote Access: Web/mobile monitoring, alarms, and cloud control
Programmable Cycles: Multi-segment programs, loops, curve editing
5. AFTER-SALES SUPPORT & RELIABILITY
Don’t overlook service and support, especially for international shipments:
Is there remote or local technical support?
Is the interface multilingual?
Are spare parts easy to get?
Are certifications like CE included for export?
A cheap machine without reliable support = expensive downtime later.
