Introduction: GWJ-4A type particle detector is developed on the basis of GWJ-4 type particle detector. The laser light resistance method adopts imported high brightness laser light source and 6 channels. It can set 10 kinds of particle size, mainly for 2010 edition " Chinese Pharmacopoeia "size injection, infusion, high viscosity, colored and organic sample particles and particle size distribution detection of a new generation of particle detector. GWJ-4A-type micro-particle detector and imported similar equipment, compared with the same technical indicators and high cost. Features: 1 performance to fully meet and better than the 2010 edition, 2005 version of "Chinese Pharmacopoeia" requirements, set Pharmacopoeia testing, anesthesia apparatus, can be directly carried out a variety of loading of the injection, sterile powder, and medicine package materials, anesthesia equipment and other medical Detection of equipment particulate contamination; 2 high-precision laser sensor, stable performance, wide detection range (1 ~ 500um), not easy to plug; unique double closed-loop stabilized circuit design to ensure low light transmission, color sample detection accuracy; 3 using advanced syringe sampling system, sampling accuracy, speed stability; suction force, can be directly detected iodine and other high viscosity samples; 4 minimum sampling volume of 0.5ml, can be directly detected small injection; 5 sampling head automatically lift, and the sampling position can be arbitrarily set to facilitate a variety of packaging, loading sample sampling; 6 intelligent high degree of data processing, storage; dot matrix large screen LCD display, the entire Chinese menu interface, easy to operate; 7 external standard keyboard, you can easily enter the drug name, batch number, specifications and other information; 8 instrument using the international photoresist instrument common magnetic stirring method, compared with the propeller-type mixing method, with a uniform mixing, easy to produce bubbles (photoresist instrument susceptible to air bubbles interference), improve the detection accuracy and repeatability advantage; 9 full voltage 100 ~ 264V range design, can overcome the power grid fluctuations, the instrument without external power supply. 10 3Q file and 3Q authentication service according to user's requirement Technical indicators: Detection range: 1 ~ 500um; Detection channel: ≥ 2um, ≥ 5um, ≥ 8um, ≥ 10um, ≥ 12um, ≥ 15um, ≥ 20um, ≥ 25um, ≥ 50um, ≥ 100um; Pharmacopoeia channel: ≥ 10um, ≥ 25um Test range: 0 ~ 9999999 tablets Sampling volume: 0.5 ~ 1000ml Sampling speed: 5 ~ 80ml / min, can be set Accuracy: ± 10% Channel resolution: ≥80% Best test concentration: 0 ~ 10000 particles / ml (5% coincidence error) Relative standard deviation: RSD ≤ 2% (standard particles ≥ 1000 particles / ml) Mixing method: magnetic stirring Mixing speed: 0 ~ 2000 rev / min Take the way out: the sampling head automatically lift, adjustable position Display operation: dot matrix LCD screen, film button, can be connected to the standard keyboard Data output: embedded micro printer Power: 100 ~ 264V, 50 ~ 60Hz Ambient temperature: 10 ~ 40 ℃
