Waterproof, shockproof. Stainless steel probe. Each unit is calibrated and supplied with a certificate of calibration traceable to NIST. Stainless-steel probe is resistant to most laboratory chemicals. Wide range covers 99 percent of the lab’s routine temperature measurements: –58 to 572°F and –50 to 300°C. Resolution is 0.1° from –20 to 200°; 1° outside this range. Reading updates every second. Accuracy ±1°C Records minimum/maximum reading At the touch of a button, memory recalls highest and lowest temperature readings over any time period. Reading is updated every second. Solid-state construction eliminates dangers inherent in breakable glass and toxic mercury thermometers. All-weather compatible Operates without fail in any lab condition—outdoors too. Waterproof construction is ideal for wet labs, wash-down areas, and virtually all field applications. Engineered to be shockproof in drop tests up to 5 feet. Bright 1/4-inch-high display is easy to view.
