Soil moisture analyzer

Soil moisture analyzerModel No.: JC10-YN-2000JS

Soil moisture analyzerProduct Introduction

YN typeIntegrating instruments and drugs, it is equipped with all the necessary equipment for conducting prescribed laboratory tests and can independently conduct measurements in townships and villages.

（1） Microcomputer multifunctional nutrient rapid testing instrument

It is the main body of this instrument, including the host, filter, colorimetric dish and other accessories.

（2） Glassware category

There are mainly volumetric flasks, graduated straws, triangular flasks, funnels, distillation tubes, absorption bottles, etc.

（3） Tray scale

It is the weighing instrument of this instrument, with a sensitivity of 0.1g. In places where conditions permit, a balance with a sensitivity of 0.01g can be used to improve analysis accuracy.

（4） Drug category

This instrument is equipped with nearly 20 types of directly available finished drug solutions and powders, which can be used to analyze more than 100 soil samples. During use, except for distilled water and alcohol that need to be supplemented by oneself, all other drugs can meet the needs.

（5） Other

This instrument is also equipped with various small items such as a calculator, filter paper, ear wash ball, aluminum box, etc. It can independently complete the determination of specified items without any laboratory equipment at the grassroots level.

Performance indicators:

（1） Measurement project

1. Hydrolyzed nitrogen, ammonium nitrogen, nitrate nitrogen, * phosphorus, * potassium, organic matter, pH value in soil.

2. Determination of Soil Moisture

3. Nitrogen, phosphorus, potassium fertilizers and urea, ammonium nitrogen, nitrate nitrogen, * phosphorus, * potassium in compound fertilizers in Hefei.

4. Nitrate nitrogen, phosphorus, and potassium in crop plants.

（2） Main technical indicators

1. Power supply

DC can work with the 12V battery on the car.

AC 220V ± 22V works normally.

2. Range and Resolution

9999 μ g/mL resolution 1 μ g/mL (1 μ g/mL ≈ 1ppm ≈ Lmg/kg the same below)

999.9 μ g/mL resolution 0. L μ g/mL

99.99 μ g/mL resolution 0.01 μ g/mL

9.999 μ g/mL resolution 0.001 μ g/mL

3. Stability

After preheating the instrument for 20 minutes, the drift of the digital display value should not exceed 0.4% within three minutes (measured for transparency)

4. Repetitive error

The error of the standard solution of 2000 μ g/mL copper sulfate shall not exceed 0.4% (for transparency measurement)

5. Linear error

The linear errors were all less than 3% when tested with potassium dichromate solutions at concentrations of 30, 90, 150, 180 μ g/mL.

6. Power consumption: ≤ 5W

（3） External dimensions and weight

Medicine box: 410 × 320 × 180mm, weighing 4.7kg (including all medication).

Instrument box: 410 × 320 × 120 mm, weighing 3.1 kg.

（4） Speed measurement

Under normal proficiency, it takes about 1.0 hour to measure fertilizer, hydrolyzed nitrogen, or soil ammonium nitrogen, phosphorus, and potassium (including soil sample pretreatment and chemical preparation).
