Remote-Reading Temperature, Relative Humidity, and Dew Point Paper-Chart Data Recorders with Audio/Visual Alarm

Image of Product. Front orientation. Data Recorders. Remote-Reading Temperature, Relative Humidity, and Dew Point Paper-Chart Data Recorders with Audio/Visual Alarm.

Remotely record temperature, humidity, and dew point up to 10 feet from the display and set the alarm to sound and flash the display if temperature readings rise above or fall below a set range. This recorder has a remote probe on a 10-ft. cable and a display that can be set to show current temperature, minimum/maximum temperature, or relative humidity and calculated dew point.
