Y-Multifunctional Clay Fertilizer Fast
Tester
Product
introduction
Instrument description:
HWSJ Multifunctional Clay Fertilizer
Fast Tester can be rapid quantitative
detect ammonium, nitrate, urea nitrogen,
phosphorus, potassium and pesticide
residues of soil, fertilizer and water
quality.
Technical parameter:
1.
10 channels light system could
rapidly test ten samples at the same
time.
2.
Can be tested multi samples at
the same time. Each sample will be
controlled by system to word
individually without mutual
interference.
3.
Absorbance value scope: above
0.000-3.000
4.
Repeatability:
±0.1%(A)
5.
Repeatability error: absorbance
（A）≤0.003
6.
Stability: photoelectricity drift（A）±0.002
(three minutes)
7.
Absorbance accuracy:
±2.0%
8.
Linear error:
±1.0%
9.
Size: 360X300X125(mm)
10.
Adopt thermal printing technology
11.
It adopts new type structure design,
Small volume, easy to carry. No
mechanical moving parts, interference
resistance, vibration resistance, high
precision, long service life of
equipment.
12.
LCD display, the reading is
accurate, intuitive
13.
Interface mode: RS-232 / USB, convenient
for data storage and transmission and
use the RS232 or USB interface
connecting with PC
communications any time, and to reach
data searching, browsing, analysis,
statistics, printing and release
information.
14.
High intelligent: the tester can
do automatically diagnosis of the system
fault.
15.
Automatically store the testing results,
large storage, and
built-in embedded thermal printer could
print the testing results real time.
16.
The tester requires spare parts
in the testing process.
17.
Reagent form (multifunction box):
reagent 100 times,
pesticide residues 500 times.
