Product Description
Product Overview
The NM-HWS temperature and humidity calibration box is a specialized calibration device used to test hair hygrometers, wet and dry bulb thermometers, digital hygrometers, digital temperature and humidity meters, and other types of temperature and humidity sensors.
The device accurately measures temperature and humidity through sensors and is controlled by an industrial programmable controller, allowing for automatic adjustment of the temperature and humidity within the calibration box, achieving high control and measurement precision, providing continuous and repeatable temperature and humidity measurements, and is also suitable for scientific research and product testing.
Technical Features
Designed with three observation windows based on the actual needs of calibrating hygrometers, it can simultaneously calibrate 10 hair hygrometers, achieving extremely high calibration efficiency.
The dual operation hole design on the box allows the calibrator to reach inside with both hands to directly adjust the tested instruments, greatly improving calibration efficiency.
The unique uniform thermal field design allows the box to achieve a uniform thermal field without relying on increased air flow, meeting the new regulations for calibrating wet and dry bulb thermometers with a wind speed of less than 0.2 m/s, while ensuring a temperature uniformity of less than 0.3℃.
Super thick insulation layer, five layers of vacuum glass for the observation window, preventing loss of cold and heat, ensuring rapid and stable temperature changes.
Automatic timed startup, allowing the device to automatically power on before work hours, enabling immediate readings after work starts, saving work time.
High-quality controller with an extended warranty period (two years warranty under normal usage conditions for the touchscreen and controller).
After installing the appropriate equipment, unattended fully automatic calibration can be achieved. The box operates automatically at various calibration points, and a digital camera automatically captures the instrument readings and generates reports.
