Charts are easy to read, duplicate, fax, scan, and file

Temperature chart recorders are for monitoring refrigerators, supply rooms, food storage, chemical warehouses, animal quarters, incubators, goods-in-transit, walk-in chambers, biological materials, and manufacturing plants. Single-use, disposable recorders display temperatures for 5, 10, or 40 days on a 91 cm (36") strip chart. A solid-state, battery-driven, quartz-crystal controlled motor turns the chart with an accuracy of better than ±1 second per day. The temperature sensor is bimetallic. Accuracy is ±1°C (2°F).

Each recorder is factory calibrated. A tamper-evident seal maintains the integrity of the unit and results. A four-part form on the front allows space to note start time and pertinent information. Shock-resistant ABS case is 13.3x9.8x6.4 cm (5¹/₄x3⁷/₈x2¹/₂").

They show temperature and time/day of occurrence.
