Product Description

Let Sonkir MS02 Soil pH Tester Make You Become a Good Plant Carer !
3-IN-1 Design
This 3-in-1 soil moisture meter is designed to better know the condition of your plant, detect soil moisture, help you know the pH value of the soil, determine if plants get enough sunlight to keep plants grow healthier !
Scientific Data Monitoring
Help you control every detail and track all changes about your plants. Keep your plants in a healthy condition through scientific data monitoring !
Special Reminder:
1. The pH function of this soil tester can not be applied to test pH value of any other liquid.
2. Since soil most often is in/close to neutral state (with pH value of 7), it is highly likely that you find the needle in display window stay still (because the default pH value is set at somewhere between 7 and 8) when you use it to test the pH value of soil. Customers sometimes are misled by this appearance and hence regard the tester as a defective unit by mistake.

How to Use:
Step 1: Switch to moisture/pH/light position according to demand.
Step 2: Insert the probe into the soil about 6-7 inches.
Step 3: Check moisture/pH/light level in the dial after 10 minutes.
Step 4: Remove probe from soil and wipe clean after each use.
Kindly Note:
1. Do not force it into very hard soil or touch hard objects since it will be easy to damage the probe.
2. Do not use it to test pure water or other liquids. It can only be used to measure soil.
3. Do not leave the meter in the soil for a long time.
4. Please wipe and clean the probe after each use.
5. If the soil is too dry the indicator will not move, and water it before testing.

Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

Learn more how customers reviews work on AmazonCustomers say
Customers find the soil meter easy to use, taking the guesswork out of plant care, and report that their plants are thriving with its help. However, the functionality receives mixed feedback, with some saying it works well while others report it stops working during the growing season. Moreover, the meter accuracy and moisture level measurements are problematic, with customers noting imprecise pH readings and high moisture level readings. Additionally, durability is a concern as the probes bend and break at first use, and value for money opinions are divided between those who find it good for the price and those who consider it a waste of money.

- Reviewed in the United States on March 1, 2025If plants could talk, they'd probably say, "Hey, could you check my pH levels, please?" Enter the SONKIR Soil pH Meter, the gadget that lets you become the plant whisperer you always knew you could be.
Using this meter is like giving your plants a health check-up without the awkward small talk. It's a 3-in-1 wonder that measures moisture, light, and pH levels, so you can finally figure out why your fern looks like it’s auditioning for a role in a horror movie.
The best part? No batteries required! It's powered by pure gardening enthusiasm and possibly a sprinkle of magic. Just stick the probes into the soil, and voilà! Instant plant diagnostics. It's like having a stethoscope for your garden, minus the cold metal and awkward doctor visits.
Now, let's talk accuracy. While it might not be NASA-grade, it’s definitely enough to impress your neighbor who thinks their lawn is the pinnacle of horticultural achievement. And who knows, with this meter, you might just dethrone them in the neighborhood plant-off.
In conclusion, the SONKIR Soil pH Meter is the sidekick every gardener needs. It’s fun, functional, and might just save you from overwatering your cactus (again). So go ahead, channel your inner plant detective and give your green friends the care they deserve. Just be prepared for them to grow so well they start demanding more space!

- Reviewed in the United States on April 25, 2025For what it's worth it makes a great moisture indicator however, the ph indicator and light indicator are the two big flaws with this. I have followed all directions given but, the ph will not move. As for the light I have literally held it in front of a bright led light bulb(meant for plant growth) and it always says dark but, if I take it outside completely then it will move towards the light. I don't know if it's only meant to detect actual sun light or if it's just faulty.

5.0 out of 5 stars A Non-Green Thumbs Little helper!
Works amazing and has helped myself who is in no way shape or form a green thumb to keep on track with how to better care for my new leaf babies! No more stressing on killing everything green and floral that adore and bring home usually to die. I use online info, along with in store experts advice on how to care for the greenery I purchase, and once home alone I have this handy tool to make sure I don’t over water, under sunlight, or kill anything in too acidic or alkaline conditions. Great tool! Two thumbs up! :)

5.0 out of 5 stars Buen medidor
Necesitaba un medidor de pH para las plantas, ya que tengo que controlarles el pH de la tierra y éste me ha ido genial.
Es muy sencillo de manejar, tiene dos agujas que metes en la tierra de forma suave, sin hacer fuerza y luego tiene una pantalla con una aguja que te indica cómo está la tierra y qué está midiendo, escoges lo que quieres que te mida y ya está. También te vale para saber si el suelo está seco o mojado o si hay humedad o no.
Todo viene en inglés pero para mí no es problema.

5.0 out of 5 stars Value for money.
Good product at this price.
Don't use same day after watering. Better when top/surface is dry and you want to measure the situation half way through.
Calibration is good.

5.0 out of 5 stars Pro e contro
Funziona tutto, prodotto non al top altrimenti il prezzo sarebbe superiore infatti ho notato al primo utilizzo che il pH me lo dava sempre alcalino anche se a me non serviva ma con un pò di carta vetro sui sensori ho risolto il problema, spero di essere d'aiuto a qualcuno x quanto riguarda il ph. Per il resto top!!!!!!!!!!
