The large digital LCD display is easy-to-read and has a resolution of .1°F/°C. Recorders feature user selectable temperature ranges and recording times, zero point calibration, and flip up pen arms for easy chart and pen changes. Each recorder comes with a 4 ft flexible type K thermocouple bead wire that is suitable for most gas, liquids, and semi-solids up to 2000°F max. Units are encased in a durable ABS enclosure for protection in harsh environments and are portable or wall mountable with the rear panel keyhole slots.
