土壤酸度水分仪

土壤酸度计又名便携式土壤酸碱度测量仪

介绍:

土壤酸碱度是限制作物生产及品质的重要因素, 该仪器使用简单方便, 可直接插入土壤.
技术参数:
PH 范围: 3-8 PH ; 水分范围: 1-8%
PH 精度: ±0.2PH ; 水分精度: ±1%
环境温度: 5-50℃
型号列表:

使用方法:

(1) 如果测定点的土壤太干燥或肥份过多, 无法测土壤的酸碱度时, 须先泼水在测定点位置上, 待 28分钟后再测定.
(2) 使用测定器前须先用研磨布, 在金属吸收板的部位, 完全的擦拭清洁, 以防影响测定值. 若是未使用新品, 金属板表层有保护油, 须先插入土壤数次, 磨净保护油层后再使用.
(3) 酸碱值测定时, 直接插入测试点土内, 金属板面必须全部入土, 约 10分钟所得的才是正确值. 土壤的密度, 湿度和肥份过多都可能影响测定值, 故必须在不同的位置测定数次, 以求平均值.
(4) 测定器在 10分钟后酸碱值很稳定, 此时按下侧边白色按钮, 湿度立即显现

NOTE:

Soil PH value is very important factor in the production of quality crops. Most crops cannot survive in soil that is to acid or to alkaline. Therefore the correct PH reading is essential to achieve optimum results.

Usage: To measure the PH and moisture value of different kinds of soil.

Range: PH=3-8 PH Moisture: 1-8 Resolution: 0.2PH

Accuracy:0.PH suitable for agricultural field and classroom experiments

Operating Temp: 5-50C (41-122 Degrees Fahrenheit)

Calibration: Remove oxidation from metal rings by light phlishing.

Instructions:

1. Remove any obstruction to the soil that requires testiong, such as surface soil, grass, leaves, pebbles, etc.If the soil is dry or contains too much fertilizer, sprinkle some water onto the soil and leave for 25-30 minutes before testing.

2. Before using the tester, be sure to thoroughly clean its metallic surface with a piece of whetting cloth. When using a brand -new tester, we advise you to insert it into the soil a few times before taking your reading, this is in order to remove any oily impurities from its metallic surface that may affect the accuracy of you soil PH or moisture reading.

3.Insert the meter directly into the soil that requires testing, embedding its metallic surface completely and tamping down the surrounding soil so that it adheres closely to the meter' s metallic electrode surface.

About ten minutes after inserting the meter in the soil, the pointer will indicate the correct value of PH or moisture.

The meter may sometimes register different values depending on the soil condition, adhesion to the meter' s metallic surface, moisture content, etc. Therefore it is advised you take an average of several measurements.

4. Press the white/green button and the pointer will indicate the correct moisture value.

5.After use, wipe the plates clean of soil or moisture.

Caution:

1. Do not leave the metal part of the tester in the soil for too long(no longer than one hour) or it will damage the metallic surface.

2.Make sure the metallic surface is clean and dry before storing.

3.Do not use the tester near magnetic objects, and keep it away from other metallic objects.

4.Do not measure liquid. This tester is not designed for measuring liquid.

5.Do not hold the tester with fingers on metallic surface. Fingerprints are greasy and re
