In the pharmaceutical industry, humidity chambers play a crucial role in assessing the stability of pharmaceutical products, particularly tablets, capsules, and powders, which are highly susceptible to changes in humidity. By subjecting these products to different humidity levels, these chambers ensure their effectiveness and safety.
3. Humidity chambers are also widely used in materials testing, where they prove to be invaluable tools for evaluating the durability and structural integrity of various materials such as polymers, composites, and metals. By subjecting these materials to diverse environmental conditions, these chambers provide valuable insights into their performance.
4. The automotive industry heavily relies on humidity chambers to evaluate the performance and longevity of automotive components. From electronics to interior materials, these components are exposed to a wide range of climatic conditions. By utilizing humidity chambers, manufacturers can ensure that their vehicles are more reliable and can withstand different environmental challenges.

Operation procedure of the Walk Stability Chamber
To operate the Walk-in Stability Chamber (25°C/60%RH), follow the steps below:
1. Switch on the main power in the control panel. The first line of the display will show the measured temperature in °C and measured humidity in %RH. The second line will display the set temperature and humidity, while the third line will display the current date or channel number and current time.
2. Set the temperature to 25°C (±2°C) through the control panel. To change the temperature, press the SET switch and enter the SET mode. Use the UP or DOWN keys to increase or decrease the temperature. The increment or decrement will be by a step of 0.1 degree for each press of the switch. If the switch is continuously pressed, the temperature will change by 0.1 degree for the first 10 steps, then by 1 degree for the next 10 steps. If the switch is released momentarily, the step size will restart from 0.1 degree.
3. Set the humidity to 60%RH through the control panel. After setting the temperature, press the SET switch again, and the second line will display “Set RH”. Use the UP or DOWN keys to set the desired humidity in %RH.
4. Set the print/recording interval through the control panel. After setting the humidity, press the SET key, and the second line will display “Prnt Intrvl:”. Set the desired print/recording interval (10 – 990 minutes) and then press the SET key.
5. Set the printing mode through the control panel. The second line of the display will show “P Mode:”. There are three printing modes available: Store Only, Store & Prnt, and Clr Memory. Select the desired mode.
6. Set the date and time. After selecting the printing mode, press the SET key. The second line will display “Set Date:”. Set the correct date and press the SET key. The display will then show “Set Time:”. Set the correct time and press the SET key. The SET mode will be terminated, and the second line will again display the set temperature and humidity.
7. Switch on the cooling system. To switch on the cooling system, press the COOL key on the front panel. The LED above the COOL key will turn on, indicating that the cooling system is on. Pressing the COOL key again will turn off the cooling system.
8. Print recorded readings. Connect the printer cable to the Centronic port and ensure that the printer is switched on with sufficient paper. Press the PRINT key, and the recorded readings will be printed, including the time, set temperature, measured temperature in °C, set humidity, and measured humidity in %RH.
9. Switching over to Boiler Heater 1 to Boiler Heater 2 / Switching over to Boiler Heater 2 to Boiler Heater 1. Turn the boiler heater selector switch from position 1 to position 2 or vice versa, as required.
10. Software operations. Verify the interface cable connection from the stability chamber to the computer. Switch on the computer and click on “Quality Loggers Data Acquisition System” with the password. Acquire data from the machine by clicking on “Data” in the menu bar and selecting the machine from which data needs to be acquired.
11. View acquired data. To view the acquired data, click on “File” in the menu bar and select “Open Log”. The Log Data window will open, and you can select the machine to view the logged data. For graphical representation, click on the “Graph” button. You can also generate the Mean Kinetic Temperature of the displayed readings by clicking on “Generate Mean Kinetic Temperature”.
12. Save the readings as a history file. To save the readings as a history file, click on the “Save as History file” button. Enter a valid file name and click OK. The data from the log file will be transferred to the history file.
13. Acquiring trend data from the history file. If a file with the same name already exists, the software will ask whether to append or overwrite the file. It is recommended to give the same file name and append the file to calculate the Mean Kinetic Temperature of recorded data. It is advised to store the log data as a history file every month and give the same name while appending the history data for a year.
14. Real-time data. To view real-time data, click on “Data” in the menu bar and select “Real Time”. You can see the real-time data of up to four machines at a time.
15. Troubleshooting. For troubleshooting, refer to the manual provided by the manufacturer, ‘Newtronic’.
Remember to lock the incubator, and the keys shall be available with the QA Officer/Executive/Manager. If the temperature exceeds the specified limits, inform the Engineering department for corrective action. If the chamber is likely to remain out of order for more than 12 hours, make alternate arrangements for storing the material. Calibration of the incubator shall be arranged by the Engineering department yearly.
