TASI TA622C Temperature Humidity Meter for Food Storage & Cold Room Monitoring Malaysia
Temperature and humidity are important environmental parameters in food storage areas, cold rooms, food processing facilities, warehouses and distribution centres.
Temperature receives most of the attention in food storage, but relative humidity can also influence storage conditions, packaging, condensation and moisture behaviour.
The TASI TA622C Digital Thermo-Hygrometer provides temperature, relative humidity, dew point and wet bulb measurements with a separate probe, making it useful for portable environmental inspection in food storage and cold room applications in Malaysia.
Why Monitor Temperature and Humidity in Food Storage Areas?
Environmental conditions can vary between different parts of a storage facility.
Possible causes include:
Frequent door opening
Warm air entering from outside
Refrigeration system operation
Airflow differences
Product loading
Different storage rack positions
Defrost cycles
Poor ventilation
Location of cooling outlets
A reading taken at only one location may therefore not represent the entire storage area.
Portable measurement allows personnel to check conditions at different points and investigate unusual environmental conditions.
What Can the TASI TA622C Measure?
The TASI TA622C measures and displays:
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 relative humidity accuracy is ±3%RH within 10–90%RH.
This allows one handheld instrument to provide several useful environmental parameters.
Why Is Humidity Important in Food Storage?
Food storage requirements vary depending on the product.
Some products and packaging can be affected by high humidity, while others may be affected by excessively dry conditions.
Humidity may also be relevant when investigating:
Condensation
Moisture on packaging
Damp storage areas
Changes in product storage conditions
Environmental differences between zones
Moisture entering when doors are opened
The required temperature and humidity conditions should always follow the particular product's storage specifications and applicable food safety procedures.
Check Different Cold Room Locations
Conditions inside a cold room may not be identical everywhere.
Personnel can use a portable thermo-hygrometer to compare measurements at:
Near the cold room door
Centre of the room
Upper storage racks
Lower storage racks
Near cooling outlets
Corners
Between storage areas
Near return air locations
This can help identify areas where environmental conditions differ from the rest of the room.
Remote Probe Advantage
The TASI TA622C uses a separate temperature and humidity probe.
This can be particularly useful for food storage and cold room inspection because the probe can be positioned at the required measurement location while the meter remains in the operator's hand.
The probe can be used to investigate:
Storage racks
Restricted spaces
Cooling outlets
Areas between stored goods
Different heights
Corners
Specific environmental zones
This is more flexible than measuring only at the location of the instrument body.
Dew Point and Condensation
Condensation can become an issue when warm humid air enters a cooler environment.
Dew point provides useful information when investigating these conditions.
When a surface temperature approaches or falls below the dew point of the surrounding air, condensation may occur.
This can be relevant around:
Cold room doors
Cooling equipment
Metal surfaces
Pipes
Storage racks
Packaging
Transition areas between cold and warm environments
The TA622C displays dew point directly, allowing personnel to obtain additional information when investigating condensation.
Wet Bulb Temperature Measurement
The TA622C also provides wet bulb temperature.
Wet bulb measurement reflects the relationship between temperature and moisture in the air and can provide useful information for environmental and HVAC assessment.
Together with temperature, RH and dew point, it gives technicians a more complete view of environmental conditions.
Data Recording for Cold Room Investigation
Cold room conditions can change throughout the day.
For example, environmental readings may change when:
Doors are opened frequently
New products are loaded
Refrigeration equipment cycles
Defrost occurs
Staff enter and leave
Outdoor conditions change
The TASI TA622C provides data recording capability and USB PC communication.
This can help personnel investigate questions such as:
How much does temperature change when the door opens?
Does humidity increase during loading?
How quickly does the room recover?
Are environmental conditions stable during operation?
Are some periods more humid than others?
Recorded measurements can provide more information than a single spot reading.
MAX / MIN / AVG for Storage Inspection
The TA622C provides MAX / MIN / AVG functions.
These functions allow users to review maximum, minimum and average readings during an inspection period.
High and low limit alarm functions are also available, allowing users to identify when measurements exceed predetermined limits.
Who Can Use the TASI TA622C?
The TA622C can be considered for:
Food manufacturers
Food warehouses
Cold room operators
Restaurants
Hotels
Supermarkets
Food distributors
Logistics companies
QA/QC departments
Facility management teams
Refrigeration contractors
HVAC contractors
It can also be used in other temperature and humidity inspection applications within the same facility.
TASI TA622C vs Temperature-Only Thermometer
A temperature-only thermometer answers one question: What is the temperature?
The TA622C provides additional environmental information:
Relative humidity
Dew point
Wet bulb temperature
MAX / MIN / AVG
High / low alarm
Data recording
USB PC communication
Separate probe
This makes it more suitable when the user needs to investigate both temperature and moisture conditions.
TASI TA622C vs Permanent Cold Room Data Logger
The two instruments serve different purposes.
A permanent cold room data logger or monitoring system is more suitable when continuous unattended monitoring, automatic alarms, compliance records or remote access are required.
The TASI TA622C is particularly useful for portable inspection and troubleshooting.
For example, if a fixed logger reports unusual conditions, a technician can use a handheld instrument to investigate different areas of the room.
Therefore, portable and permanent monitoring instruments can complement each other.
Is TASI TA622C Suitable for Cold Room Monitoring?
Yes, for portable environmental inspection within its specified measurement range.
Its temperature, relative humidity, dew point and wet bulb functions allow personnel to investigate more than temperature alone.
However, applications requiring continuous food safety records or regulatory monitoring should use an appropriate dedicated monitoring system according to the facility's requirements.
Frequently Asked Questions
Can TASI TA622C be used in a cold room?
Yes, provided the measurement conditions are within the instrument's specified operating and measurement requirements.
What is the TA622C temperature measurement range?
The specified temperature range is -40°C to 80°C.
Does TA622C measure humidity?
Yes. It measures relative humidity from 0 to 100%RH.
Can it measure dew point?
Yes. TA622C displays dew point temperature.
