1. Measurement Contexts
- Relative Humidity Meters for handheld checks of ambient humidity and temperature — rooms, HVAC systems, storage areas and building surveys — where sensor accuracy, response time and probe options drive the choice.
- Humidity & Temperature Transmitters when the reading has to run continuously into a BMS, PLC or logger, with measuring range, communication interface and mounting format to weigh up.
- Dew Point Meters on coating, drying and surface-preparation work, where the surface-to-dew-point margin decides whether the job can go ahead, in handheld and logging models.
- Infrared Surface Thermometers for quick non-contact surface-temperature checks in food safety, maintenance and process inspection, judged on emissivity setting, distance-to-spot ratio and temperature range.
For the dry-film thickness of a coating and the wider surface-preparation inspection the dew-point check feeds into, continue under Coating Inspection.
