Supported Applications

The Omega OS418-LS-Series is a non-contact handheld infrared thermometer designed to measure surface temperature and relative humidity. As indicated by its series title, the instrument combines IR thermal sensing with humidity measurement capabilities for field applications.

Operating Conditions & Performance

This product bundle contains attribute-level data only; specific performance specifications such as measurement ranges, accuracy classes, response times, or operating temperature limits are not provided in the source documentation. Consequently, no quantitative values can be asserted regarding the series' operational envelope.

Measurement Technologies

  • Infrared (IR) non-contact surface temperature sensing
  • Relative humidity measurement

The device is configured as a handheld unit with a pistol-grip form factor, intended for portable use.

Configuration Options

The series includes the OS418-LS model. The available configuration features:

  • Housing Style: Pistol grip design optimized for handheld operation
  • Sensor Types: Integrated infrared sensor and relative humidity sensor

No additional options, output signal types, process connections, or material specifications are documented in the current bundle.

Key Product Differences

The OS418-LS-Series is represented by a single enabled variant (OS418-LS). No alternative models, housing styles, sensor elements, or output configurations are listed within this series data. Distinctions between sub-models cannot be described due to the absence of comparative specification data.

What is the maximum distance you can get a temperature?

Asked by: Rob123
It depends on the dimensions of what you are measuring. In this case, if the item is 1 inch wide, then you would have a maximum distance of 12 inches. Hence, the field of view is 12:1 ratio. (As long as you fill the field of view).
