• Designed specifically for glass, plastics, or metals applications Specialty infrared thermometers have optimized spectral responses for glass, plastics, or metals applications. The glass model is designed for use in glass manufacturing. Use the plastics models in thin film (under 0.4 mm) plastics applications such as lamination and film orientation. The metals models are ideal for forging, forming, and extruding operations. Note: The metals models are not recommended for use with aluminum. |Each model provides a precise sighting system. The glass model 39800-40 and metals model 39800-46 feature scope sighting. They have a through-the-lens optical system and a circular reticle to precisely define target area. The plastics models 39800-42 and -43 and metals models 39800-47 and -48 feature single lasers that indicate the center of the area you are measuring. |Choose from two laser types-class IIIa laser models for maximum brightness, or class II models where regulations require use of low-power lasers. |Lock the trigger for long-term monitoring. Store up to 100 temperature readings at selectable time intervals with built-in clatalogger. Configure output as either RS-232 or as a one millivolt per degree analog output (cables and software sold separately below). |Thermometers display minimum, maximum, differential temperature, and average temperature in °F or °C and feature adjustable emissivity and memory recall. Other features include backlit display and an audible and visual alarm that signals overrange and underrange temperature conditions. |Each thermometer includes four AA batteries, padded nylon carrying case, shoulder strap, and instructions. Adapters for 115 or 230 VAC operation are availableâ€order below. Shpg wt 5.0 lb (2.3 kg).
