Temperature, humidity, and pressure difference tester

1、 Product Introduction
Yufeng Ruilin WH-1Temperature, humidity, and pressure difference testerIt is a multifunctional temperature and humidity meter and micro pressure gauge with high measurement accuracy, stable performance, and easy operation. The instrument adopts high-precision sensors to monitor the micro pressure difference between different environments, display the real-time differential pressure between two environments and the temperature and humidity of the instrument, and monitor the pressure difference and temperature and humidity between different levels of clean rooms. It can reflect pressure changes in real time based on the fluctuation of pressure sources, and is widely used for measuring positive, negative, and differential pressures of gases. It is used for testing and calibrating pressures in various environmental monitoring stations, laboratories, medical and health care, building air conditioning and heating, and purification rooms. It is also suitable for departments and units that frequently go out for testing, and is a commonly used instrument for pharmaceutical companies and quality supervision departments to implement GMP standards.
