When the recorded temperature reached is a question of one point only, or space is at a minimum, Wahl Single-Position Temp-Plates provide history at a glance. Easy-to-read recording position is simply either "off" (light gray) or "on" (black) at one temperature point only. Perfect for warranties and critical process points. Labels are printed with either °F or °C. Temp-Plates are priced, sold, and shipped in reclosable storage boxes with labels of the same part number. The 210 Temp-Plate comes in boxes of 10 labels. Temp-Plate cover material is made of Mylar (clear) for ranges 100/350°F (38/176°C) and Kapton (amber) for ranges above 350°F (176°C). Please order by using base part number 210 with suffix identifying the desired temperature point in °F or °C. Example: 210-123C. Dimensions: 1" x .75" (25 x 19 mm).
