K-Type Thermometer Probe-Style Temperature Meter for Industrial Furnaces, Temperature Probes for Solder Baths, Molten Aluminum, Flames, and Air Ovens Measurement Range: -200°C to 1,350°C; -328°F to 2,498°F (This is the instrument’s display range. The standard thermocouple cable included with the thermometer has a measurement range of -50°C to 250°C. The actual measurement range depends on the probe. If you need to measure high temperatures, liquids, or surface temperatures, please select the appropriate probe.) Operating Voltage: 5.2 V–6.2 V (4 AA batteries) Current Consumption: 7.5 mA (measurement mode); 12 mA (control output mode); 30 µA (off mode) Resolution: “0.1” and “1.0” °C/°F Sampling Rate: 10 times per second Measurement Accuracy: -200°C to 1,370°C: ±(0.2% + 1°C); -328°F to 2,498°F: ±(0.2% + 2°F); Note: This error does not include probe (sensor) error Operating Environment: Temperature 27°C, humidity less than 70% RH Battery: 1.5V
