Heat Stress Monitors

Absolute Instrument supplies WBGT heat stress monitors for Singapore worksites, construction projects, shipyards, process industries, factories, training academies and outdoor teams that need practical heat-stress monitoring. Our range supports MOM heat-stress management with portable WBGT meters, real-time monitoring systems and site-ready solutions for workplace safety teams.

AISYS real-time WBGT monitoring systems

The AISYS WBGT Heat Stress Monitoring System is our key differentiator for worksites that need continuous visibility, large displays, alerts and remote monitoring. It can support integrated environmental monitoring workflows where heat stress, noise, TSS, dust and other site conditions need to be managed together.

Portable and fixed WBGT monitor options

Use portable WBGT meters for inspections, audits, mobile safety teams and spot checks. Use fixed or real-time WBGT monitoring when a site needs continuous records, alerts, display panels or remote visibility. Absolute Instrument can help compare AISYS, KestrelMet, TSI QuestTemp and LSI Heat Shield options for your workplace requirements.

WBGT monitoring for MOM heat-stress measures

Singapore heat-stress guidance highlights WBGT monitoring for outdoor work, especially during hotter parts of the day. For higher-risk workplaces such as construction sites, shipyards and process-industry environments, a suitable WBGT meter or fixed monitoring system helps safety teams monitor site conditions and implement work-rest, hydration and shade measures.

Frequently asked questions

What does WBGT measure?

WBGT means wet bulb globe temperature. It combines environmental factors such as air temperature, humidity, radiant heat and air movement into a practical heat-stress index for workplace safety teams.

Who needs WBGT monitoring in Singapore?

WBGT monitoring is especially relevant for outdoor work, construction sites, shipyards, process-industry workplaces, factories, training academies and teams managing heat-stress risk.

Should we use a portable or fixed WBGT monitor?

Portable WBGT meters are useful for inspections, audits and mobile work teams. Fixed or real-time systems are better when a site needs continuous monitoring, alerts, display panels or remote visibility across the workday.

How often should WBGT be measured?

MOM guidance refers to hourly WBGT monitoring during work hours, especially during hotter periods of the day. Workplaces should check the latest MOM/WSH guidance and their own risk assessment requirements.

Do WBGT meters need calibration?

Yes. WBGT meters should be maintained and calibrated according to manufacturer requirements, or annually if the manufacturer does not specify a calibration interval.
