Traceable® Products Traceable® Dual-Channel Thermometer Model 4029

Thermometer shows two probe readings and the difference between readings 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 range to 1999°F 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. Chemical and shock-resistant case Ideal for quality control, measuring temperatures in wastewater, petroleum products, and biotechnology applications. Rugged case is chemical and shock-resistant ABS plastic. Traceable to NIST for accuracy To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Comes ready to use 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. 1112.
