Power Meter TLD6070 series with a chip microcomputer control and the large-screen graphics LCD, it can provide precision measurement from 850 to 1625nm wavelength ranges and measuring range including -70 dBm to +6 dBm, -50 dBm to +26 dBm. Optical power meter can test the PM power to the light, light stability, insertion loss, optical transmittance, reflectance of light and so on. It widely used in optical fiber communications, CATV, Fiber Optical Sensors etc. It is indispensable for scientific research and engineering construction.

Introduce:Automatic seed counter, grain counter, nut counterAutomatic seed counter for the determination of the weight per thousand kernels of seeds and for the preparation of samples for germination and cultivation tests.for any grain sizes from 0.7 to 12 mm. Features:1. high counting speed2. precise count3. easy to use4. quiet operation5. adjustable size and speed6. low noise operation     The feed container is held in place by an electromagnet and vibration induced during counting. The material to be counted reaches the outlet and falls into the receptacle through a photoelectronic counter.     The Counter selects its counting speed automatically dependent on the size of the material to be counted. This guarantees optimum use of the counting capacity and reduces counting time to a minimum whilst maintaining count accuracy. Shortly before counting is completed the counter reduces its counting speed so that no more seeds are counted than have been preset. Counting speed may also be manually adjusted. The instrument can recognize when the receptacle or the feed container is absent, stops counting and reports the fact on the display so that no...
