TASI TA622C Temperature Humidity Meter for Electronics Manufacturing Malaysia
Temperature and humidity can be important environmental parameters in electronics manufacturing, PCB assembly, electronic component storage, production rooms and QA/QC areas.
Electronic components, materials and manufacturing processes may be sensitive to environmental conditions. Temperature and relative humidity can also affect worker comfort, storage conditions, condensation risk and electrostatic control procedures.
The TASI TA622C Digital Thermo-Hygrometer measures temperature, relative humidity, dew point and wet bulb temperature and uses a separate measurement probe, making it useful for portable environmental inspection in electronics manufacturing facilities in Malaysia.
Why Monitor Temperature and Humidity in Electronics Manufacturing?
Environmental conditions inside a factory can vary from one location to another.
Possible causes include:
Air-conditioning distribution
Production equipment generating heat
Opening of doors
Outdoor humidity
Different production zones
Airflow restrictions
Storage conditions
Changes in occupancy
HVAC system performance
A fixed environmental sensor provides useful continuous information, but it measures conditions only at its installed location.
A portable temperature and humidity meter allows technicians to investigate individual production areas and compare environmental conditions between different locations.
What Can the TASI TA622C Measure?
The TASI TA622C provides four environmental measurements:
Temperature
Relative Humidity (RH)
Dew Point Temperature
Wet Bulb Temperature
The specified temperature measurement range is -40°C to 80°C.
Relative humidity measurement covers 0 to 100%RH.
Temperature accuracy is specified at ±0.5°C, while humidity accuracy is ±3%RH within 10–90%RH.
This allows technicians to evaluate both thermal and moisture conditions using one handheld instrument.
Temperature & Humidity Checks on the Production Floor
Electronics manufacturing facilities may contain several production and support areas.
The TA622C can be used to compare conditions around:
PCB assembly areas
Production lines
Component storage
QA/QC rooms
Testing areas
Packing areas
Equipment rooms
Air-conditioning outlets
Material storage areas
Measurements taken at several locations can help determine whether environmental conditions are reasonably consistent across the facility.
Separate Probe for Flexible Measurement
The TASI TA622C uses a separate temperature and humidity probe.
This configuration allows the sensing probe to be positioned close to a specific measurement point while the user keeps the display in a convenient viewing position.
It can be useful for checking:
Between production equipment
Near electronic component storage
Different heights
HVAC outlets
Restricted areas
Equipment cabinets
Specific work zones
This provides more flexibility than relying only on a sensor built directly into the meter body.
Relative Humidity and Electronics
Relative humidity can be an important parameter in electronics manufacturing and storage.
Environmental conditions may be relevant to:
Electronic components
PCB materials
Packaging
Moisture-sensitive materials
Storage areas
ESD control procedures
Production processes
However, acceptable humidity limits depend on the specific process, component, facility requirements and applicable standards.
The TA622C provides the measurement information, while the user should compare the readings against the appropriate internal or industry requirements.
Temperature & Humidity for ESD-Controlled Areas
Electrostatic discharge is an important consideration in many electronics manufacturing environments.
Humidity can influence electrostatic behaviour, but humidity measurement alone does not confirm whether an ESD control programme is compliant or effective.
The TASI TA622C can provide environmental temperature and RH measurements as part of a wider ESD control programme.
Other appropriate ESD testing instruments and procedures may still be required depending on the facility's requirements.
Dew Point Measurement
The TA622C also displays dew point temperature.
Dew point can be useful when investigating conditions associated with condensation.
This may be relevant around:
Cold equipment surfaces
Air-conditioning systems
Metal components
Storage areas
Temperature transition zones
Cooling equipment
When surface temperature approaches the dew point of the surrounding air, condensation may become more likely.
Having dew point information available directly on the meter can assist technicians during environmental troubleshooting.
Wet Bulb Temperature
The TASI TA622C provides wet bulb temperature in addition to standard temperature and relative humidity.
Wet bulb information can assist HVAC and facility personnel when evaluating air-conditioning and environmental conditions.
This means one instrument can provide several useful environmental parameters for production, maintenance and facility teams.
Data Recording for Factory Environmental Investigation
Factory environmental conditions may change during different production periods.
For example, temperature and humidity may change because of:
Equipment operation
Increased production activity
Shift changes
Door opening
HVAC cycling
Outdoor weather conditions
The TASI TA622C provides data recording capability and USB PC communication.
Recorded measurements can help investigate questions such as:
Does temperature rise during production?
Does humidity change between shifts?
Are some production areas consistently warmer?
Does opening a loading door affect RH?
Did environmental conditions improve after HVAC maintenance?
This provides more information than relying on a single instantaneous reading.
MAX / MIN / AVG Functions
The TA622C provides MAX / MIN / AVG functions.
These allow users to review maximum, minimum and average readings during a measurement period.
High and low limit alarm functions can also help users identify measurements that exceed predetermined limits.
Who Can Use the TASI TA622C?
The TA622C can be considered for:
Electronics manufacturers
PCB manufacturers
EMS companies
Semiconductor-related facilities
Electronic component warehouses
QA/QC departments
Production engineers
Facility management teams
Maintenance departments
HVAC contractors
The same instrument can also be used in laboratories, warehouses, server rooms and other controlled indoor environments.
TASI TA622C vs Basic Hygrometer for Factory Use
A basic digital hygrometer can display current temperature and humidity at one location.
The TA622C provides additional professional functions including:
Separate measurement probe
Temperature measurement
Relative humidity measurement
Dew point
Wet bulb temperature
MAX / MIN / AVG
High / low limit alarm
Data recording
USB PC communication
This makes the TA622C more suitable for technicians who need to investigate and compare environmental conditions at multiple locations.
TASI TA622C vs Fixed Factory Environmental Monitor
A fixed monitoring system is normally more suitable when the requirement is:
Continuous 24/7 monitoring
Multiple permanent sensors
Automatic alarms
Remote monitoring
Long-term records
The TASI TA622C is particularly useful for portable inspection and troubleshooting.
For example, when a fixed sensor indicates abnormal humidity, a technician can use the TA622C to investigate different locations around the production floor.
The two types of instruments can therefore complement each other.
Is TASI TA622C Suitable for Electronics Manufacturing?
Yes.
Its combination of temperature, relative humidity, dew point, wet bulb, separate probe and data recording makes the TA622C useful for portable environmental inspection in electronics manufacturing facilities.
For specialised ESD, cleanroom or regulated process monitoring, additional instruments and appropriate procedures may still be required.
