Description
The HI981030 Soil pH Tester is designed to measure the pH or acidity of the soil as a key factor in ensuring strong and healthy plant growth. It features a single button operation system and is easy to use. It has a compact and waterproof casing and automatic pH calibration at one or two points. All readings are automatically compensated for temperature variations with a built-in temperature sensor.
Direct Soil MeasurementDirect soil pH testing offers the benefit of not needing to take soil samples, as the pH is tested right in the ground.
- Inspect the pH probe to ensure the bridge electrolyte gel has not dried out. Refill if necessary.
- Calibrate the pH probe prior to measurement.
- Use an auger to make a hole down into the soil (app. 20 cm). The hole needs to be the same depth each time to avoid pH discrepancies.
- Add some distilled or deionized water to the hole; the soil should be damp but not saturated.
- Wash the electrode with tap water and insert into the hole.
- Allow for the reading to develop or stabilize.
- After measurement, gently wash off leftover soil (avoid using a cloth or a wipe).
Note: Direct soil pH testing is not recommended if the ground is stony or hardened as the electrode can be damaged. To prepare the soil prior to measurement, take a representative soil sample and add HI7051 Soil preparation solution.
