Yieryi 7-in-1 Soil & Water Tester

The product shown is a 7-in-1 Soil & Water Tester, a multifunctional digital gardening tool designed to measure soil pH, moisture, fertility (nutrients), sunlight intensity, soil temperature, air humidity, and ambient temperature. This specific design is widely associated with the brand Yieryi, which specializes in water and soil testing instruments for hobbyist and professional agriculture.

Originally developed by Chinese manufacturers like Shenzhen Yage Technology Co., Ltd. (the company behind the Yieryi brand), these devices are produced in industrial hubs in China. They are popular globally due to their portable, battery-operated design and clear backlit LCD displays. The brand is a prominent player in the electronic testing equipment market, often distributed through major online retailers and specialized gardening shops.

While the device is sold under several generic names and through various OEM distributors, Yieryi remains the primary brand identity for this specific 7-in-1 model. Ownership and manufacturing reside in China, where the technology was refined to combine multiple sensors into a single handheld probe for domestic and agricultural use.
