Model: PI RTD

Any industrial installation has several electrical thermometers such as Thermocouples & RTDs. At a regular interval, these instruments are required to be checked against a ‘Standard Industrial RTD', which has accuracy to the level of 1/10th DIN. with its vast experience in design and manufacturing of precision instruments has developed ‘Standard PT100 Industrial RTD' which caters to such requirements of client.


These RTDs are traceable to National Physical Laboratory (NPL) and are either provided with Original Calibration Certificate from NPL with very low level of uncertainty or Internal Certificate traceable to National laboratory. These Standard PT100 Industrial RTDs are manufactured with 4 wire design to deliver highest performance.
