Quick verdict
A wired probe meter that reads soil electrical conductivity and temperature on a backlit LCD in ten to fifteen seconds, with an IP67 probe for wet soil. EC tells you how much salt and fertiliser is in the root zone, the number that explains burnt tips and stalled growth in containers and greenhouses. It is a budget instrument, so calibrate against known readings and treat trends as more reliable than absolutes.
Strengths
- Reads EC and temperature together in one probe
- Backlit LCD is far easier to read than dial meters
- IP67 waterproof probe for wet soil and hydroponic media
- Ten to fifteen second readings
- Low price for a digital EC instrument
Weaknesses
- Generic brand; accuracy should be checked against a reference
- Probe EC reads differently from a lab slurry test
- Battery-powered electronics need care around water

The Number Behind Overfeeding
Burnt leaf tips, stalled growth and white crust on the pot rim are all symptoms of salt build-up from fertiliser, and the way to see it before the plant does is soil electrical conductivity. EC rises with dissolved salts. TEKCOPLUS’s 2-in-1 meter reads EC and soil temperature from one wired probe onto a backlit LCD, with an IP67 probe for wet media, at a price that makes EC research accessible to container gardeners and greenhouse growers.
This review is based on the listing specifications and on how probe EC meters are used in horticulture generally. We have not used this meter ourselves and the brand is a generic importer.
What It Measures
Push the probe into moist soil, wait ten to fifteen seconds and read EC and temperature. Low EC means the medium is depleted and plants are hungry; high EC means salts have accumulated and roots are at risk. Temperature matters in itself, for germination and root growth, and because EC drifts with temperature, so reading both together makes the EC figure more meaningful.
Where It Is Most Useful
Containers and raised beds with soilless mixes, greenhouse crops and anything fed with soluble fertiliser. In these the root zone has little buffer and EC swings quickly. Owners use it to decide when to flush a pot with plain water and when to feed, and to compare pots to find the one that is struggling.
Accuracy and Calibration
Probe meters in soil read differently from laboratory slurry tests, and a generic instrument’s absolute accuracy is uncertain. The reliable use is relative: compare readings over time and between plants, and check the meter against a known standard solution if you need confidence. Treated that way it is genuinely informative.
Build
The probe is IP67 sealed and tolerates wet soil and hydroponic media. The handheld display unit is not, so keep it dry. The backlit screen is a real improvement over needle dials that are hard to read in a greenhouse.
Who Should Buy It
- Container and greenhouse growers feeding with soluble fertiliser.
- Anyone seeing salt burn or crust and wanting to know why.
- Hydroponic hobbyists checking media EC.
Common Owner Complaints
Readings that do not match lab tests and uncertainty about calibration. Both come with budget probe meters and are managed by using it for trends.
Alternatives to Consider
Bluelab and Hanna make calibrated EC meters for serious growers at several times the price. A pour-through test with a solution EC pen is the standard container method. Multi-function soil meters add pH and light but read EC coarsely.
Verdict
For the price, this meter puts a useful EC and temperature reading in the hands of anyone growing in pots or a greenhouse. Use it to track trends and compare plants, check it against a standard when it matters, and it will catch overfeeding before the leaves do.

TEKCOPLUS 2-in-1 Digital Soil EC and Temperature Meter FAQs
Electrical conductivity rises with dissolved salts, mostly fertiliser. Low EC means hungry plants; high EC means salt build-up that burns roots. It is the fastest way to see whether you are over or under feeding.
Labs test a soil-and-water slurry, which gives a different number from a probe in moist soil. Use the probe for trends and comparisons between pots, not for matching lab figures.
EC readings shift with temperature, and soil temperature itself matters for germination and root activity. The combined probe gives both in one insertion.
Read a known solution or compare pots you have fertilised identically. Consistent relative readings are what a budget meter can deliver.
