DS18B20 Waterproof Temperature Probe — Stainless Steel 6×50mm, 100/200/300cm Cable

A heavy-duty waterproof temperature probe for demanding sensing applications. This DS18B20 stainless steel probe features a 6×50mm stainless steel sheath housing the DS18B20 sensor, connected via a flexible tinned-copper cable available in 100cm, 200cm, or 300cm lengths. The 30-strand tinned wire construction provides superior flexibility and oxidation resistance compared to standard DS18B20 cables — ideal for permanent installations in aquariums, soil, pipes, and industrial environments.
