| PTL Temperature Measuring Board | |
| to measure the temperatures in the bases or in the fixing surfaces for appliances ａnd luminaries in operation |
| according to | IEC 60335-1 | :2006-09 § 11.2 ａnd § 11.3. |
| Standard Outfit: | |
| 1 | Plywood board, 20 mm thick, with frame on all sides ａnd with covering board at the lower side, together approx. 150 mm thick, with 4 feet, |
 | 1 | set Measuring Points consisting of: |
| | Copper Disks, diameter 15 mm, 1 mm thick, embedded at distances of 50 mm x 50 mm in the plywood board, |
| and Fine-wire Thermocouples nickelchromium-nickel (NiCr-Ni), soldered to the back of the copper disks, thermoelectric wires with a diameter of 0.3 mm, insulated with glass-silk or similar temperature resistant material, |
| 1 | set of change-over switches to ｓelect the lines resp. rows of the copper disks, to connect the selected copper disk with socket-outlet or temperature indicating instrument, |
| 1 | socket-outlet, two-pole, almost free of thermoelectric voltage, plug with cable of nickelchromium-nickel, length 1.5 m, for the connection of a external measuring instrument, |
| 1 | temperature indicating instrument supplied by battery, ａnd switch to ｓelect instrument or socket-outlet. |
