Professional Exporter of Testing Machinery
Multi-functional nutrient tester instrument and drugs in one, it is equipped with the necessary provisions of the project necessary for the company's unique part of the equipment, in the township, village, mobile test service vehicles and other grass-roots service points for the determination.
(1)the use of microprocessor technology, digital lines, programmed design, single-chip control, touch-button, liquid crystal display.
(2)pay, straight (car) dual use.
(3)built-in thermal printer, store print test results.
(4)the use of filters as a light source, silicon semiconductors as a signal receiving system, life of up to 100,000 hours.
(5) the cartridge part of the use of more than two optical path design, to avoid the different channels of the system error.
(6)the work stability is better than the national standard JJG179-90 6 times the index, repeatability to achieve grating spectrophotometer indicators.
