Accurate humidity measurement is essential in industries such as pharmaceuticals, food storage, electronics, and meteorology. Hygrometers play a key role, and their reliability directly affects product quality and compliance.
Maintaining accurate readings requires regular verification. Many laboratories and industrial users face challenges like unstable conditions, uneven humidity, and inconsistent results, which can reduce confidence in calibration data.
LIB industry offers high-quality climatic test chambers that provide controlled temperature and humidity, ensuring stable and repeatable hygrometer calibration for industrial and laboratory applications.
Not all environmental chambers are designed for calibration purposes. Standard chambers may meet general testing needs, but they often fall short when used for hygrometer verification.
LIB industry climatic chambers address these limitations:
In standard climatic test chambers, temperature and humidity may vary across the workspace. LIB industry chambers use advanced airflow design to ensure uniform distribution.
Impact:
All hygrometers experience the same conditions, providing consistent and comparable readings.
Humidity and temperature may drift over time in conventional systems. LIB industry climatic chambers maintain controlled environmental conditions with a humidity deviation of ±2.5% RH and temperature fluctuation of ±0.5°C.
Impact:
Reliable, repeatable conditions reduce calibration errors and improve testing confidence.
Standard chambers often take longer to reach target conditions. LIB industry chambers are designed with efficient heating, cooling, and humidification systems to reach setpoints quickly and maintain them consistently.
Impact:
Shorter calibration cycles, improved workflow efficiency, and reduced operator intervention.

LIB industry chambers maintain stable conditions suitable for industrial verification and routine calibration, ensuring consistent test results.
To meet various application needs, LIB industry offers two humidity measurement methods:
Wet-bulb method (gauze type): Reliable and resistant to long-term drift.
Capacitive sensor: Fast response, low maintenance, and easy operation.
Users can choose the appropriate method depending on calibration requirements, maintenance preferences, and test standards.
LIB industry chambers feature advanced airflow systems to ensure:
Temperature uniformity: ≤ ±2.0°C
Humidity uniformity: ≤ ±2.5% RH
Result:
All hygrometers in the chamber experience uniform environmental conditions, ensuring consistent calibration results.
The intelligent controllers of LIB industry chambers enable:
Multi-step temperature and humidity programming
Automatic cycling and dwell time control
Real-time monitoring and data logging
Optional communication interfaces (RS485, Ethernet) allow integration with external data acquisition systems.
Benefits:
Highly repeatable test conditions
Reduced operator intervention
Improved calibration efficiency
LIB industry chambers support a broad operating range, allowing:
Low humidity: down to 20% RH (with optional dry air system)
High humidity: up to 98% RH
Combined temperature-humidity testing
This ensures calibration can cover multiple points across real operating environments, including extreme humidity conditions.
LIB industry chambers are designed for practical laboratory and industrial use, featuring:
Heated observation window to prevent condensation
Multiple cable ports (Ø50 mm / Ø100 mm optional) for sensor connections
Stainless steel interior for durability and easy cleaning
Touch-screen interface for intuitive operation
Advantage:
Easy setup for multiple hygrometers, simple connection to reference instruments, and real-time observation without disturbing test conditions.
