• Feature adjustable emissivity, recall, HI\/LO alarms, MIN, MAX, DIF, AVG, and data output • Take temperature measurements in both bright-light and low-light areas with new model 39800-35 These infrared thermometers offer a variety of aiming systems to fit your exact requirements. Scope models feature a through-the-lens optical system and a circular reticle to precisely define the target area. |Use a laser sighting model to determine the center of the area you are measuring. Laser spots on the target indicate the approximate diameter. Use single-laser models for longrange measurements. Dual and crossed laser models have lasers that are aligned with the thermometer's optics. New model 39800-35 offers both scope and laser sighting. |Choose from two laser types-class IIIa laser models for maximum brightness, or class II models where regulations require use of lowpower 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. Other features include adjustable emissivity, recall, backlit display, and an audible and visual alarm. | 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).
