Authorised Vaisala Distributor in Malaysia
Seacom is an authorised Vaisala distributor in Malaysia for industrial measurement instruments and continuous monitoring systems. We supply humidity and temperature sensors, dew point meters and transmitters, CO₂ instruments, pressure instruments, moisture-in-oil probes, biogas instruments, weather and wind sensors and continuous monitoring systems related products.
Choosing an instrument starts with understanding the application. Apart from the measuring range, we need to consider the operating conditions, installation and connection to your existing system. Our team can help you check these details and select a suitable model.
If you are replacing an existing instrument, send us a clear photo of the model label and the complete order code. For a new installation, share your application or project specification so we can review the requirements with you.
Our Vaisala Range and Local Support
We support customers across Malaysia in pharmaceutical manufacturing, semiconductor production, battery manufacturing, data centres, HVAC and general industry. Some enquiries involve a single replacement probe; others involve instruments and monitoring points for a complete facility. In either case, the selection should match the actual site requirements.

Vaisala Products and Instrument Families
The categories below cover our main Vaisala instruments. Click the heading to view the products, or send us your requirements if you need help comparing the models.
Dew point
For compressed air, dryers, dry rooms and process gases, the required dew point is an important starting point. We also need to check the line pressure and sampling arrangement. Use a fixed transmitter for continuous measurement or a portable meter for checks at several points.
Product families: DMP probes and DMT transmitters, with the model selected for the measuring range and installation conditions.

Continuous monitoring
Vaisala viewLinc brings readings, alarms and historical records into one monitoring system. For GxP applications, involve QA when defining the records, access permissions and qualification requirements. These should be agreed as part of the system scope.
System components: viewLinc software, RFL100 loggers, AP10 access points, VDL200 PoE loggers and CAB100 cabinets, selected according to the monitoring points and connections required.

Portable measurement
A portable instrument is useful for commissioning, maintenance checks and investigating unusual readings. The probe and accessories are as important as the handheld unit, particularly when measuring compressed air or taking readings at difficult locations.
Portable options: Indigo80 with compatible humidity, dew point or CO₂ probes. For an existing meter, provide the instrument and probe model numbers so compatibility can be checked.

Gas measurement
Ventilation systems, incubators, bio-decontamination equipment and biogas processes require different gas measurements. Confirm the gas, concentration range and operating conditions before selecting the probe.
Product families: GMP CO₂ probes, HPP hydrogen peroxide probes and MGP biogas probes. The parameters measured depend on the selected model.

Pressure
Barometric pressure and differential pressure serve different applications. For cleanroom pressure monitoring, check the pressure relationship and range between the two spaces. For atmospheric pressure, select a suitable barometer.
Product families: PTB barometers and PDT differential-pressure transmitters for suitable weather, laboratory, cleanroom and HVAC applications.

Moisture in oil
Moisture-in-oil measurement helps track the condition of compatible oils during operation. Instrument selection depends on the oil type, temperature, pressure and available connection. These details should be checked before deciding on the probe.
Product families: MMP moisture-in-oil probes and suitable portable configurations. Confirm compatibility with the oil and the measurement required.

Weather and wind
For outdoor installations, consider both the weather parameters and the conditions at the mounting point. Exposure, mounting position and the connection to your system should be reviewed together with the instrument selection.
Product families: WXT530 Series weather transmitters and WMT700 ultrasonic wind sensors.

Vaisala Applications in Malaysia
The same measurement parameter can serve different purposes from one site to another. These application guides explain where the instruments are used and what to check during selection.
local_hospital
Pharmaceutical — GxP Environmental and Process Monitoring
Measure environmental and process conditions in cleanrooms, production areas, storage and equipment. Define what each transmitter will measure, then review the records and alarms required from viewLinc CMS. The GxP scope should be agreed with the engineering and QA teams.
memory
Semiconductor — Critical Moisture and Process Measurement
Critical moisture measurement may be required in dry gases, drying processes and production equipment, alongside cleanroom humidity, temperature and pressure. Select low-dew-point instruments according to the process limits, pressure and installation arrangement.
battery_charging_full
Battery Manufacturing — Dry Rooms and Drying Processes
Dry rooms and drying processes need measurements that cover the specified moisture limits. Select suitable dew point instruments, and review the monitoring locations together with temperature and pressure requirements.
dns
Data Centres — Air and Cooling Measurement
Measure air conditions in server rooms, aisles and ventilation systems using suitable humidity and temperature instruments. Vaisala options also include differential-pressure measurement and TMI110 for cooling-water temperature. Select each instrument for its part of the air or cooling system.
ac_unit
HVAC — Room, Duct and Building Measurement
Room and duct instruments provide the readings used by the building control system. Choose HVAC humidity instruments, temperature sensors, CO₂ transmitters and pressure instruments according to the location, required accuracy and BMS interface.
settings_input_component
Compressed Air — Dew Point and Dryer Monitoring
Dew point measurement helps the maintenance team check air dryness and dryer performance. Consider the dryer type, working pressure and required dew point when selecting the instrument. Our portable dew point measurement guide covers checks at different points in the system.
invert_colors
Oil Moisture — Maintenance and Process Measurement
Use suitable moisture-in-oil instruments to follow dissolved moisture and temperature in compatible lubrication, hydraulic or transformer oils. Review the readings against the equipment conditions and maintenance requirements.
nature
Biogas and Biomethane Measurement
Raw-biogas measurement and methane-slip measurement in upgrading offgas require different probe capabilities. Confirm the gas composition, concentration range and process conditions before selecting the instrument.
wb_sunny
Weather and Wind Monitoring
For exposed sites, the mounting position and installation conditions affect the measurement. Select suitable weather and wind instruments for the parameters required, and review how the readings will reach the monitoring system.
Portable Meter or Permanent Transmitter?
The choice depends on how often you need the reading and what you will do with it.
settings
Permanent Transmitter
A fixed transmitter remains at the measurement point and sends readings to a suitable control or monitoring system. Choose this arrangement when the process needs continuous measurement. Recording and alarms depend on the connected equipment and configuration.
work
Portable Meter
A portable meter is suitable for periodic checks, commissioning and troubleshooting at several locations. Select the probe and sampling accessories for the application, and allow the reading to stabilise before making a comparison.

Replacing an Existing Vaisala Instrument
When replacing an older Vaisala instrument, check more than the model series. The measuring range, output, power supply, process connection and probe dimensions all need to suit the existing installation.
For example, DMT153 can be considered when reviewing a DMT152 replacement. An older DMT340-series installation may require a suitable DMP probe with a compatible Indigo transmitter. The replacement arrangement depends on the complete model code and configuration.
Send us a clear photo of the instrument label and, if available, the existing specification or wiring details. This helps us check the suitable replacement and identify any installation changes before you order.
