Page 3: General Description
Humidity Cabinet 39-1300, 39-1601 General Description The cooled laboratory humidity cabinet provides the user with extremely accurate and safe temperature control over a wide temperature range. Heating Low wattage heaters are attached to the outer surface of the inner chamber in such a manner as to ensure even heating throughout the chamber. -
Page 4: Installation
Humidity Cabinet 39-1300, 39-1601 Humidity A wide range of fixed relative humidities can be maintained by adding a suitable saturated salt solution to the base of the chamber. See Section 4 for details. Installation Connect the 3-core cable to a 240V AC, 50Hz mains supply as follows:... - Page 5 Humidity Cabinet 39-1300, 39-1601 The JUMO dTRON 316 microprocessor temperature controller on your incubator has two LED displays. The upper display, which is red, represents the actual chamber temperature. The lower display, which is green, represents the target temperature. The controller has 4 buttons marked as follows;...
- Page 6 Humidity Cabinet 39-1300, 39-1601 Setting An Over Temperature Cut-Out Value If, for example, you would like to operate your incubator at +20.0°C, an over temperature cut-out value needs to be programmed into the cut-out. We recommend that the cut-out value is set to 2 degrees higher than your chamber temperature. In the example above, the over temperature cut-out set point needs to be set +22°C.

Page 7: Humidity Control
Humidity Cabinet 39-1300, 39-1601 Humidity Control A wide range of fixed and relative humidities can be achieved by adding a suitable saturated salt solution to the base of the chamber. The relative humidity of air in contact with saturated salt solutions reaches known equilibrium values at certain temperatures. - Page 8 Humidity Cabinet 39-1300, 39-1601 The chamber should be regularly de-frosted as a substantial build-up of ice in the air circulation duct will restrict the airflow and affect the incubators performance. It is recommended that the service ports on the right of the incubator remain sealed with the threaded red bungs supplied to reduce the tendency for humidity in the air to condense out in the chamber.

Humidity Cabinet 39-1300, 39-1601 APPENDIX A Digital Data Recorder (Temperature & Humidity) Introduction The Eurotherm nanodac Digital Data Recorder is a simple to use modern version of an analogue paper chart recorder. Data can be viewed on screen or downloaded for viewing on a computer. - Page 10 Humidity Cabinet 39-1300, 39-1601 Normal operating screen (°C) Normal operating screen (%RH) temperature humidity The screen changes automatically between every few seconds during normal operation. 9907X0093 Issue 3...
- Page 11 Humidity Cabinet 39-1300, 39-1601 Normal Operation The recorder starts recording data automatically. The screen shows a live animated graph (in real time) for both the temperature and the humidity. The screen changes between temperature humidity every few seconds. Large numbers in the top right corner of the...
- Page 12 Humidity Cabinet 39-1300, 39-1601 Control Panel Buttons It is not necessary to enter the menu or change any settings for normal operation. The recorder has been pre-configured to work optimally without any adjustment or input from the user. The buttons on the recorders control panel perform these functions:...
- Page 13 Humidity Cabinet 39-1300, 39-1601 Viewing Graph Data On Screen Historical graph data can be viewed on-screen without affecting the recording process. To view historical graph data: 1) Press the button. The following screen will appear: 2) Press the button and select History.
- Page 14 Humidity Cabinet 39-1300, 39-1601 5) Press the button to scroll FORWARD in time. 6) Press the button to change between temperature humidity screens. 7) When you have finished viewing the historic graph data, press the button. The following screen will appear:...
- Page 15 Humidity Cabinet 39-1300, 39-1601 USB Socket A panel mounted USB socket is included next to the recorder. The recorder does not need a USB flash drive inserted to record data - the data is recorded and stored inside the recorder as standard.
- Page 16 Humidity Cabinet 39-1300, 39-1601 Downloading Graph Data The recorder holds approximately 1 years’ worth of data internally before data is overwritten. The recorded data is stored in .csv format. Recorded data can be downloaded onto a USB flash drive when required. This can be done daily, weekly, or monthly.
- Page 17 Humidity Cabinet 39-1300, 39-1601 Viewing the Downloaded Graph Data On your computer, navigate to where the downloaded data has been stored on the USB flash drive. The normal data storage location will be on the flash drive in a folder called “history”.
