Features  

1.     The overall performance of this model meet and better than requirements of 2010 version of "Chinese Pharmacopoeia", set the pharmacopoeia detection, anesthesia equipment, may directly have a detection of particulate pollution directly in a variety of packs of injection, asepsis powder, drug packaging materials, anesthesia utensils, medical apparatus and so on.

2.     It adopted such a high precision laser sensor, stable performance, wide detection range(1~500μm), not easy to plug, Unique stable optical circuit design of the double-loop to ensure low transmittance light and accuracy of colored sample detection,  

3.     Advanced precision syringe sampling system,the sampling accuracy is high, stability of speed, Suction capacity is strong, You can directly detect iohexol, high viscosity samples and so on.

4.     Minimum sample volume is 0.5ml, small injections can be directly detected.

5.     Sampling head could go up and down automaticlly and the sampling position can be set at random, that take sampling easyin the various amount and packs of injection

6.     A high degree of intelligence, automatic data of processing and memory, A lattice of big-screen LCD, full menu interface, ease to operate.

7.     Add a standard keyboard, you can easily and flexibly enter the drug name, batch number, specifications and other information

8.     Selects magnetic stirrer mode which is used universally in international instruments of the light blockage method. Compared with propeller mixing, it can stir well and not easy to cause air bubble so as to improve detection accuracy and repeatability (It is easy to interfere with a equipment of laser blockage method by bubbles). It is the advantage that it improve the detection accuracy and repeatability.

9.      Voltage range: 100 ~ 264V, The instrument can overcome the power fluctuations,  no need external manostat.
