WKS-1200 Masks Respiratory Resistance Tester

The WKS-1200 Masks Respiratory Resistance Tester is designed to assess the inhalation and exhalation resistance of respirators and mask protective products under specified conditions. It is utilized for testing and inspection by national labor protection equipment inspection agencies or manufacturers. The tester complies with standards GB2626-2006 and GB/T32610-2016.

Specification:

• Flowmeter: 0 L/min to 100 L/min, Accuracy: ±2%
• Micromanometer Range: -1000Pa to 1000Pa, Accuracy: 1Pa
• Air Pumping Volume: No less than 100L/min
• Ventilation Constant: (85±1)L/min
• Dimension: 380*620*825mm (Head model specifications: 30, 25, 20)
• Power Supply: AC220V, 50Hz

Features:
The instrument includes an adjustable flow air source, a standard human head model, and a dual-pipeline system for inhalation and exhalation resistance measurement. The flow sensor is highly sensitive with minimal starting flow, utilizing a thermal mass flowmeter that negates the need for temperature and pressure compensation, ensuring precise measurements. Multiple sensors on a single chip enhance the sensor’s range ratio. It offers high stability, accuracy, excellent repeatability, low power consumption, low pressure loss, and fast response speed. The data logger features a graphic dot matrix LCD with a resolution of 128×64, supporting both English and Chinese interfaces for ease of operation.
