Waterproof Digital Thermometer with Display

Waterproof Digital Thermometer with Display provides a simple and economical solution for accurate temperature monitoring across wet or humid environments. Designed for greenhouses, aquariums, swimming pools, and refrigeration spaces, this compact temperature measurement device combines a clear digital screen with a durable waterproof probe for reliable readings. The sensor supports a wide measurement range from -50℃ to 110℃ and refreshes data every 1.5–2 seconds, enabling quick observation of environmental changes. A one‑meter probe cable allows flexible placement while the low‑power electronic thermometer operates for months using compact button batteries.

Note: This product does not contain batteries. Two button batteries (LR44/AG13) are required for normal operation and must be purchased separately.

Reliable Waterproof Probe for Liquid and Environmental Monitoring

A fully sealed temperature probe allows dependable operation in damp or submerged conditions. The stainless probe and one‑meter cable enable measurement inside fish tanks, water containers, refrigerators, or greenhouse soil environments without exposing the display unit to moisture. Continuous immersion up to one meter depth over extended periods supports aquatic monitoring scenarios where stable waterproof performance is essential.

Wide Temperature Range with Clear Digital Display

The digital sensing system measures temperatures from -50℃ to 110℃ with a resolution of 0.1℃ and an accuracy of ±1℃. Fast refresh intervals of approximately 1.5 to 2 seconds provide near‑real‑time feedback for environmental monitoring tasks. The integrated display panel presents readings clearly, enabling quick visual inspection without requiring additional equipment or complicated setup.

Ultra‑Low Power Operation for Long‑Term Monitoring

An energy‑efficient sensing circuit consumes a maximum operating current of only 4uA, enabling extended operation using two LR44/AG13 button cells. This low‑power temperature monitoring unit can run continuously for roughly half a year under typical conditions, making the module suitable for long‑term environmental observation in locations where frequent battery replacement would be inconvenient.
