note:
1. The soil detector only tests soil and soil, etc. It is not applicable to dry flour, small stones, organic wood, wood with liquid, particles, etc.
2. When the detector probe is inserted into the soil, please try to keep it at a depth of 10CM and above (just inserting the probe will have no effect and will not move)
3. In order to improve the accuracy of the measurement results, please use the method of multi-point test and average value when measuring the value
4. When using, pay attention not to touch the stone when inserting the electrode, otherwise the force is too strong, otherwise it will easily damage the electrode
5. The detector should not be inserted in the soil for a long time, it is easy to oxidize and damage the probe
6. After use, please clean the detector probe, the probe should be kept dry and stored
7. The detector is suitable for detecting moist soil. If the soil is too dry, please moisten the soil first, as the humidity will be too high or too low to affect the pH value

A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS can tell you your overall water purity level,which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS is a great tool for drinking water,water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS is a rugged model that includes a protective carrying case. This is the worlds most popular handheld TDS meter for industry professionals. ts Ideal for Commercial Use Its Includes a Carrying Case with Belt Clip Hold Function: Saves Measurements for Convenient Reading and Recording Highly Efficient and Accurate Due to Its Advanced Microprocessor Technology Built-in Digital Thermometer, Display: Large and Easy-to-read LCD Screen. The AquaLutio Digital TDS Water Meter is ideal for testing applications such as hydroponics and gardening, pools and spas, aquariums and reef tanks, water ionizers, Water Filter. drinking water and more. TDS Water Meter is ideal for testing applications ideal drinking water, Water Filter, carbon filters, spring water, hard water, average tap water, Refrigerator Water Filter, Water Filter, brita filter, Reverse osmosis, reverse osmosis filter.
