Monitor temperatures using two probes. Dual display simultaneously shows temperature of both probes or temperature of one probe and the difference between probes (T1-T2). With two separate sensors you can note temperature variations in an incubator/oven or temperature gradations in a water bath. Sense changes between inlet and outlet temperatures in any system. HOLD switch allows the display to be frozen to capture readings. Temperature ranges are –50.0 to 1999°F and –50.0 to 1230°C. Resolution is 0.1° under 200° and 1° above 200. Meter only accuracy is 0.3% plus 1°C. Extra-large, 3/4-inch-high display is readable from 15 feet. Uses all Type-K thermocouple probes. Ideal for quality control, measuring temperatures in wastewater, petroleum products, and biotechnology applications. Rugged case is chemical and shock-resistant ABS plastic. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from the manufacturer’s ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Supplied with 9-volt alkaline battery and two fast-response, Type-K beaded probes, which indicate temperature changes in less than one second. Cable length is 4 feet. Measures 3 x 7 x 1-1/4 inches and weight is 9 ounces. Replacement battery Cat. No. CON1112.
