Palmer Wahl 440_Labels | Unmarked Security Micro Round Temp-Plate Labels | 4 points, 7.62 mm
The Palmer Wahl 440_Labels are special unmarked security Temp-Plate® labels in the micro round 7.62 mm (0.30 in) format. None of the four indicator positions is printed with a temperature; instead the customer selects any four available points between 37 and 176 °C (100 and 350 °F), and a legend packed in each box identifies them. Each position turns permanently black at its rating, so the label is well suited to spotting warranty-related overheating in electronics without revealing the trip points.
Key features
- Four customer-selected points, 37 to 176 °C (100 to 350 °F)
- Unmarked face; identification legend supplied with each box
- Round micro label, one of the smallest Temp-Plate formats
- ±1% NIST traceable accuracy; NIST calibration data available
- Self-adhesive mounting on most surfaces
- Recloseable box of 10 labels
Labels with any point at or below 43 °C (110 °F) are classed as low-temperature and should be refrigerated on receipt so they do not turn early.
