Technical parameters of soil acidity meter:
Scope: 3-8pH;
Humidity range: 10%-80%
Accuracy: + 0.2pH;
Ambient temperature: 5-50 degrees centigrade
Suitable for the measurement of the acidity and alkalinity of different surface
Matters needing attention:
1., the metal probe must ensure that it is fully contacted with the soil and compacted.
2., if the soil is too dry, it can be watered for 20 minutes.
3, when the instrument is inserted into the soil, it should be inserted clockwise.
4, when using for the first time, be careful to insert the soil several times, and polish the metal probe surface to protect the oil layer before using it.
5, when measuring, make sure that the metal surface is fully contacted with the soil and compacted, so that the measured data is more accurate.
6, when inserting soil, don't push it too hard. If you don't get stuck, don't blindly use brute force to cause damage.
7, when measuring humidity, we need to loose the soil, and the front probe can not pass the soil lightly, so that no G can use external force. Because there is a lot of water in the soil layer. If the soil is pressed, the water will overflow and concentrate on the surface of the probe. The measurement data is too large.
