TADT-4G Portable Humidity Generator (2.3 L)
Introduction
Key Features
· Efficient Test Chamber Space
The test chamber offers a volume 3 to 5 times larger than comparable products.
· Test Chamber Compatibility
It is compatible with a wide range of immersion-type chilled mirror dew point sensor heads, allowing for convenient comparative calibrations.
· Sensor Port Design
Modular sensor ports accommodate temperature and humidity probes and transmitters of various diameters.
· Measurement Chamber Window and Lighting
A transparent observation window combined with an integrated lighting system facilitates easy reading of small-scale temperature and humidity instruments.
· Small Probe Calibration Capacity
Supports simultaneous calibration of 10 to 15 miniature temperature and humidity probes.
· Digital Meter Calibration Capacity
Supports simultaneous calibration of 3 to 5 standard-sized digital temperature and humidity meters.
· Test Chamber Temperature Accuracy
Ensures temperature uniformity of ≤ 0.1°C across the full calibration range of 5°C to 50°C.
· Working Status Monitoring
Real-time display of liquid level and desiccant status.
· External Signal Input
Equipped with four external signal input channels: 0~1 V, 0~5 V, 4~20 mA. (Applicable models: TADT-1G/TADT-2G)
· Humidity Conversion Function
Built-in humidity conversion software supports conversion between temperature, humidity and dew point temperature.
· Temperature & Humidity Trend Display
Equipped with a 7-inch color LCD touch screen, supports temperature and humidity curve display.
· Drying Cylinder Replacement Design
External-mounted drying cylinder allows online desiccant replacement when the instrument is powered on.
· Drying Cylinder Zone Function
Dual-zone design supports both molecular sieve and color-changing silica gel desiccants.
