Platinum thermal resistance is a kind of accurate, sensitive and stable temperature sensor. The temperature sensing element can be quite small so it can be made into all kinds of micro temperature sensor probe. Features: PT100 platinum resister waterproof temperature sensor temp probes. High measuring accuracy, stable performance. External insulated shielding and internal fiberglass insulation. Wide temperature range from -20 to 250. Small structure, wide use, good reliability and short thermal response time. Specifications: Type: Platinum thermal resistance waterproof Temperature Range: -20-250 Sensor Size: 4 x 30mm / 0.15 x 0.18" Cable Length: About 50cm / 19.68" External Shielding: Insulated shielding Internal Insulation: Fiberglass Quantity: 10pcs Weight: 37g(approx.)
