Benetech GM1365 for Clean Room Temperature & Humidity Monitoring Malaysia
Benetech GM1365 for Clean Room Temperature & Humidity Monitoring Malaysia
Temperature and relative humidity are important environmental parameters in many clean room and controlled-environment applications.
Even when a clean room appears stable during normal working hours, conditions can change because of HVAC operation, production load, occupancy, door opening and differences between daytime and nighttime operating schedules.
The Benetech GM1365 Temperature & Humidity Data Logger provides automatic recording of temperature and relative humidity over time. This makes it a useful instrument for general environmental investigation, HVAC troubleshooting and preliminary monitoring where its specifications meet the application's requirements.
Why Monitor Temperature and Humidity in a Clean Room?
A clean room is usually associated with airborne particle control, but environmental conditions may involve several parameters.
Depending on the facility, these can include:
Temperature
Relative humidity
Differential pressure
Air velocity
Airflow
Airborne particle concentration
The GM1365 specifically monitors:
Temperature + Relative Humidity
It does not replace instruments required for the other clean-room parameters.
Spot Checking Can Miss Environmental Changes
Suppose a clean room operator checks conditions three times per day:
9:00 AM → Normal
1:00 PM → Normal
5:00 PM → Normal
Everything appears stable.
However, what happens after production stops?
A logger may reveal:
7:00 PM → HVAC operating mode changes
10:00 PM → Temperature begins increasing
2:00 AM → Humidity increases
6:00 AM → HVAC returns to daytime operation
8:30 AM → Conditions normal again
Manual daytime checks would not reveal this pattern.
Why Historical Data Matters
A handheld temperature and humidity meter answers:
“What are the conditions now?”
A data logger helps answer:
“Were the conditions stable throughout the monitoring period?”
This is useful when investigating intermittent environmental problems.
Instead of relying on staff observations, users can review recorded measurements.
GM1365 for HVAC Troubleshooting
HVAC performance is closely connected with temperature and humidity control.
A data logger can help investigate questions such as:
Does temperature increase after working hours?
Does humidity rise overnight?
Are conditions different during weekends?
Does production equipment increase room temperature?
How quickly does the room recover after a door is opened?
Are some areas less stable than others?
The recorded data provides useful information for facility and HVAC teams.
Compare Different Clean Room Locations
Environmental conditions may not be identical throughout a room.
Potential differences can occur:
Near Supply Air → Different temperature
Near Return Air → Different conditions
Near Door → Greater influence from adjacent areas
Near Equipment → Additional heat
Room Corner → Different airflow
Main Working Area → Different load and occupancy
Multiple data loggers can be used for preliminary comparison.
Example Monitoring Setup
For troubleshooting, a facility might deploy:
Logger A → Main Work Area
Logger B → Near Equipment
Logger C → Near Entrance
Logger D → Opposite Side of Room
The recorded data can then be compared.
If Logger B consistently records a higher temperature than the other locations, facility personnel have a specific area to investigate.
Production Equipment Can Affect Temperature
Manufacturing equipment can generate heat.
The environmental load may therefore change when production starts.
A data logger can help compare:
Before Production
vs
During Production
vs
After Production
This can provide useful information when determining whether HVAC capacity or airflow requires further investigation.
Humidity Monitoring in Controlled Environments
Relative humidity may be relevant to certain:
Electronic processes
Manufacturing materials
Laboratory activities
Packaging operations
Storage conditions
However, acceptable humidity limits depend on the specific process and facility.
A data logger records the actual condition; the user must compare those measurements with the required environmental limits.
GM1365 for Preliminary Clean Room Investigation
GM1365 can be particularly useful as a portable troubleshooting instrument.
For example, if staff report:
“Humidity becomes unstable every morning.”
A logger can record conditions for several days.
Instead of sending a technician to observe the room continuously, the recorded data can reveal when the change begins and whether it repeats.
This makes environmental troubleshooting more efficient.
Is GM1365 a Clean Room Validation Instrument?
Not by itself.
Formal clean room qualification or validation may require specialised instruments, procedures and documentation.
Depending on the applicable standard and facility requirements, testing may involve:
Airborne particle counters
Differential pressure meters
Air velocity meters
Airflow measurement
Temperature and humidity measurement
HEPA filter integrity testing
Recovery testing
GM1365 is a temperature and humidity data logger, not a complete clean-room validation system.
Calibration Requirements
If temperature and humidity records are used as part of a formal quality system, users should determine the required calibration and traceability.
Consider:
Required accuracy
Calibration points
Calibration interval
Traceability requirements
Certificate requirements
Internal SOP
Customer requirements
A general-purpose logger should not automatically be assumed suitable for regulated applications solely because it measures the required parameters.
Clean Room Data Logger vs Permanent Monitoring System
These solutions serve different purposes.
Portable Data Logger
Useful for:
Temporary investigations
HVAC troubleshooting
Environmental surveys
Comparing different areas
Short- or medium-term trend recording
Permanent Monitoring System
More appropriate when the facility requires:
Continuous central monitoring
Remote access
Real-time alarms
Automatic notifications
Permanent sensors
Centralised historical records
For some facilities, both systems can be useful.
Other Instruments May Be Needed
If the objective is a broader clean-room environmental assessment, additional instruments may be required.
For example:
Temperature & Humidity → Data Logger
Air Velocity → Anemometer
Differential Pressure → Pressure Meter
Airborne Particles → Particle Counter
This is why MTM Precision focuses on the customer's measurement problem, not simply one instrument model.
Who Can Use GM1365?
Potential users include:
Electronics factories
Semiconductor-related facilities
Pharmaceutical facilities
Laboratories
Medical-device manufacturers
Precision manufacturing
QA/QC departments
Facility-management teams
HVAC contractors
Suitability should always be checked against the specific monitoring requirement.
