Temperature and humidity are important environmental parameters in data centres, server rooms, network rooms and IT equipment rooms.

 

Servers, switches, UPS systems and other electrical equipment continuously generate heat. At the same time, excessive humidity may increase the risk of condensation, while very dry conditions may contribute to electrostatic discharge concerns.

 

For maintenance teams, facility managers and HVAC technicians, a portable instrument such as the TASI TA622C Digital Thermo-Hygrometer provides a practical way to investigate temperature and humidity conditions at different locations.

 

Why Monitor Temperature and Humidity in a Data Centre?

 

Data centre environmental conditions are not always uniform.

 

Even when the room air-conditioning system appears to be operating normally, different temperatures may exist between:

 

Server racks

 

Hot aisles

 

Cold aisles

 

Rack inlet areas

 

Rack exhaust areas

 

CRAC / CRAH outlets

 

Raised-floor air outlets

 

UPS rooms

 

Network rooms

 

Electrical rooms

 

A single wall-mounted temperature sensor may not reveal these local differences.

 

Portable measurement allows technicians to investigate specific areas and identify potential hot spots or unusual humidity conditions.

 

What Can the TASI TA622C Measure?

 

The TASI TA622C provides four important environmental measurements:

 

Temperature

 

Relative Humidity (RH)

 

Dew Point Temperature

 

Wet Bulb Temperature

 

The specified temperature measurement range is -40°C to 80°C, while relative humidity measurement covers 0 to 100%RH.

 

Temperature accuracy is specified at ±0.5°C, with humidity accuracy of ±3%RH within 10–90%RH.

 

This combination makes the TA622C useful for professional environmental inspection rather than simple room temperature checking.

 

Check Server Rack Inlet Temperature

 

One useful application is measuring the temperature of air entering server racks.

 

Instead of measuring only the general room temperature, technicians can position the TA622C probe near different rack inlet locations.

 

For example, measurements can be compared between:

 

Bottom of the rack

 

Middle of the rack

 

Top of the rack

 

Different racks

 

Different cold aisles

 

If one area is consistently warmer than another, further investigation of airflow, cooling distribution or equipment loading may be required.

 

Identify Hot Spots Around IT Equipment

 

A data centre may have acceptable average room temperature while still containing localised hot spots.

 

These may be caused by:

 

High equipment density

 

Poor airflow

 

Blocked ventilation

 

Incorrect floor tile arrangement

 

Cooling imbalance

 

Air recirculation

 

Rack configuration

 

Changes in IT load

 

The portable TA622C allows technicians to take measurements at multiple points rather than assuming one reading represents the entire room.

 

Why Is the TA622C Remote Probe Useful?

 

The TA622C uses a separate temperature and humidity probe, which is particularly useful for data centre inspection.

 

The sensing probe can be positioned close to the required measurement location while the operator keeps the main display in a convenient viewing position.

 

Possible measurement locations include:

 

Server rack inlet

 

Rack exhaust

 

Between adjacent racks

 

Air-conditioning outlet

 

Raised-floor outlet

 

Equipment cabinet

 

Network cabinet

 

Restricted spaces

 

This provides greater flexibility compared with a meter where the environmental sensor is integrated directly into the instrument body.

 

Relative Humidity Monitoring

 

Temperature alone does not provide a complete picture of the environmental condition.

 

Relative humidity should also be considered.

 

The TASI TA622C allows technicians to check both temperature and RH using one handheld instrument.

 

This can be useful during:

 

Routine facility inspection

 

HVAC maintenance

 

Cooling system troubleshooting

 

Server room commissioning

 

Environmental investigation

 

Preventive maintenance

 

If unusual conditions are detected, technicians can investigate the HVAC or environmental control system further.

 

Dew Point Measurement

 

The dew point temperature provides additional information about the moisture condition of the air.

 

This is useful when technicians need to assess potential condensation conditions around cooled surfaces, air-conditioning equipment, piping or other areas.

 

Because the TA622C displays dew point directly, users can obtain this information without carrying out a separate manual calculation.

 

Wet Bulb Temperature

 

TA622C also provides wet bulb temperature measurement.

 

Wet bulb information can be useful for HVAC technicians when evaluating air-conditioning and environmental conditions.

 

Having temperature, RH, dew point and wet bulb information available from one instrument makes the TA622C useful for broader HVAC and facility troubleshooting.

 

Data Recording and USB PC Communication

 

Environmental conditions can change over time.

 

A reading taken at 9:00 AM may be different from conditions later in the afternoon when IT equipment loading or cooling demand changes.

 

The TASI TA622C provides data recording capability and supports USB PC communication.

 

This can help technicians investigate questions such as:

 

Does server room temperature increase during peak operating periods?

 

Which area experiences the highest temperature?

 

Does humidity change significantly during the day?

 

What happens when cooling equipment cycles?

 

Are conditions stable after HVAC maintenance?

 

Recorded data can provide a clearer picture than relying only on a single spot measurement.

 

MAX / MIN / AVG for Environmental Inspection

 

The TA622C provides MAX / MIN / AVG functions.

 

These can be useful during an inspection because technicians can observe maximum, minimum and average environmental readings over a measurement period.

 

High and low limit alarm functions can also assist users when checking against predetermined measurement limits.

 

TA622C vs Fixed Data Centre Environmental Monitoring

 

The TA622C should not be confused with a permanent data centre monitoring system.

 

A fixed monitoring system is normally preferred when the requirement includes:

 

Continuous 24/7 monitoring

 

Multiple permanent sensors

 

Remote notifications

 

Network connectivity

 

Centralised dashboards

 

Long-term unattended monitoring

 

The TASI TA622C is a portable inspection instrument.

 

It is particularly useful when a technician needs to physically investigate a location, compare multiple measurement points or troubleshoot an abnormal environmental condition.

 

The two solutions can therefore complement each other.

 

Who Can Use the TASI TA622C?

 

The TA622C can be considered by:

 

Data centre facility teams

 

Server room operators

 

IT departments

 

Facility management companies

 

HVAC contractors

 

M&E contractors

 

Maintenance technicians

 

Electrical contractors

 

Network infrastructure companies

 

Building maintenance teams

 

Is TASI TA622C Suitable for Data Centre Inspection?

 

Yes.

 

For portable environmental inspection, the combination of temperature, relative humidity, dew point, wet bulb, remote probe and data recording makes the TA622C a useful instrument for data centre and server room applications.

 

It allows technicians to investigate environmental conditions at specific locations instead of depending entirely on the room’s fixed sensors.

 

For critical facilities requiring permanent remote environmental monitoring, however, a dedicated fixed monitoring system should also be considered.
