The liquid particle counter of the photoresist method is mainly composed of a sampling system, a sensitive area, a counting system and the like. The particles enter the sensitive area, the optical path is blocked, the photoelectric intensity changes are received on the photoreceiver, and converted into voltage pulse signals, and the number of particles passing through different sizes is recorded through different voltage valves (or pulse height analyzer channels). According to the measurement purpose of the instrument, it can be divided into the measurement of solid particles in the oil phase and the aqueous phase medium; according to the measurement method of the instrument, it can be divided into three types: fixed particle size, settable particle size and no particle size. . Saddle wiper arms are typically used on windshields that are taller than they are wide - like tugs, fishing vessels, transit buses, etc. Saddle Wiper Arm,Windshield Wiper Arm,Universal Wiper Arm,Car Wiper Arm COMOTECH ASIA PACIFIC (HANGZHOU)CO.,LTD , https://www.capwiper.com
They have two parallel struts and move the Wiper Blade from side to side. They are structurally strong - to handle large wiper blades, and require larger, more powerful motors.
Unlike some competing models, both the drive and slave arms of these Wexco pantographs are strong, heavy duty struts (rather than a drive strut and a slave tube).
• All pantograph arms have saddle style blade attachments
• Heavy duty construction you can see and feel when you pick the arm up
• Black finish is black powder-coated stainless steel
• Silver finish is bare matte (shot peened) stainless steel
Measuring principle and classification of liquid particle counter by photoresist method
The photoresist particle counter is a measurement method developed along with cleanliness measurement and pollution degree monitoring. It is divided into two types according to the measurement object: one is a common name particle counter for measuring the size and quantity of particles in a gas, also called Dust counter; the other is the measurement of the size and quantity of particles in the liquid, called the photoresist particle counter.
