Usage
1. Take off the protective cap from metal probe.
2. Press OFF/ON button. Tester displays 0.
3. Quick testing: Water the soil with distilled water before testing. Make sure the water can go 10 cm
deep the least. Best humidity is 70%-80%. Insert the metal probe into soil vertically and clockwisely, to
about 6-8 cm deep. Make sure the soil has thorough contact with metal probe. After about 6 seconds, the
tester will display the measured value.Tightness of soil will affect measuring result. Multiple tests at the
same and different points should be performed and take the average as final result.
‚accurate testing：Use a 200ml beaker container, mix dried soil with distilled water at the ,stir and make it into a mud form. Put the metal probe into the mud about 6-8CM deep. About 6 seconds, the tester will display the measured value.
4. Wipe the metal probe with towel or tissue paper after each test. Make it clean and dry, till the display shows 0.
1. Do not use the tester to measure liquid. Do not measure dry and hard soil. Do not leave the metal sensor
inthe wet soil long (take out immediately after each test) . Or it will damage the metal sensor and shorten the
lifespan. Wipe the metal sensor clean and dry after each test.
2. The tester is factory calibrated. No need for calibration for users.
3. If the display fades, jumps, power supply may be not enough. Replace the battery.
4. When store the tester, put the protective cap onto the metal probe. Avoid touching metal probe with
hands, avoid scratch with hard objects. Keep the tester in clean and dry environment. Keep it away from
magnetics.
5. Measuring units: 1mg/Kg = 1mg/l =1ug/ml=1ppm
