YN-2000B Types Soil and fertilizer fast tester

Introduction of instrument：
It can test N,P,K.LCD display. direct calibration, direct reading, digit display,alternating and direct two usage, resolving power 0.01.the tester is a kind of microcomputer testing instrument and the testing items, fast property are all the same as type YN-1000 but resolving power is 0.01,linear error decreases one time than type YN-1000 and having capable extending function.capable extending and testing PH value and temperature
Technique parameter：
resolving power ：    0.001-9999
repeatability error：    ≤0.5（the liquor of potassium dichromate）
the stability of instrument：≤0.5(transparence measuring)
power：    ≤5W
linar error：≤3%(bluestone detecting)
test speed：testing one soil sample(N、P、K)≤one hour
Characteristics of instrument：
1.multitudinous functions：it can test N、P、K of soil、fertilizer、foliage；
soil（fertilizer）organic matter；soil moisture(use combustion method)、
neutral and micro element(boron、manganese、iron、cuprum、calcium、
magnesium、sulfur、chlorine、silicon、zinc etc.)、PH value、total nitrogen；
reductive sugar、total sugar of tobacco and so on.（you can purchase all
kinds of medicament)
2.the YN 2000B fast detecting instrument is the integration of medicine、implement、apparatus and convenient to take, it is similar to a small laboratory.it adapted the agriculture serving department to test soil and fertilize or differentiate the true and false of fertilizer.
3.easy-to-operating、fast speed，it adoped original uniting extractant (invention patent) which can finish extracting N、P、K in five minutes，the finished product medicament can be directly used when open the bottle and needn’t collocate.
4.credible capability：the work stability is six times of GB JJG179-90，
the repeatability reaches the guide line of grating spectrophotometer.
After service：
1.We have established the distributing and after-sale units in agriculture department and instrument company in 30 provinces (cities, municipality)all over the country.
2.We promise that we will repair our productions freely in five years and repair our productions lifelongly；we post the instruments to you freely and teach you how to use them freely.
3.There are many experts of plant protection,bio-chemistry,creature engineering,mechanism and electron etc.in our company and they can provide counseling freely to you all over the country.
