SSPRT provides an affordable alternative for precision temperature measurement and calibration in labs & fields. Metal Sheathed Semi Standard Platinum Resistance Thermometer is widely used as a reference to calibrate various temperature probes, particularly in secondary calibration laboratories. SSPRT is constructed with a 6 mm outer diameter metal sheath of high durability. Inside the sheath, the sensing element is protected to shield the sensor from contamination by free-floating metal ions found within the metal environment at high temperatures. The electrical configuration is a four-wire current potential hookup to eliminate the effect of lead wire resistance. A special powder mixture is filled into the sensor capsule to support the element wire to protect the element from mechanical shocks. The element is housed in a special protective Assembly to ensure minimum drift over long term use.
