BeskrivelseThe CT87 Series Temperature Recorder is a precision instrument used to monitor and record temperature on a 152 mm (6") circular chart. The CT87 may be carried as as portable instrument or mounted in a fixed location. The CT87 offers a variety of features to meet any temperature recording requirement. A combination of three temperature ranges and three chart speeds provides a high degree of flexibility. In addition, the chart rotation may be set for single or continuous turn operation as required by a particular application. To protect the data being recorded, the CT87 uses an automatic battery backup to maintain operation during a mains power failure. Note: The unit has limitations on reading at the low end of the scale as a safety feature to keep the pen from hitting the chart hub.
