Showing Results for Fluke 2190A

The Fluke 2190A digital thermometer is a portable, stackable, five digit thermocouple thermometer capable of temperature measurements over a range of ‑252°C to +2471°C (-486°F to +4480°F) with a resolution of 0.1°. 

• Thermocouple types: Type depends on microcomputer type:
  • Microcomputer type 1: J, K, T, C, R thermocouple types
  • Microcomputer type 2: J, K, E, S, R thermocouple types
  • Microcomputer type 3: JDIN, K, TDIN, B, R thermocouple types
• Resolution is 0.1°C or °F
• Input connection: Two wires on screw terminal isothermal block
• Measurement methods: Dual-slope integration under microcomputer control, 100 ms integration period, three reading per second
• Digital linearization (microcomputer controlled) of the thermocouple inputs
• Common mode rejection: ≥160 dB at dc, 50, 60, and 400 Hz ±0.1%, with 100 Ω unbalance at input
• Input impedance: 1000 MΩ at dc
• Maximum source impedance: 2 kΩ
• Automatic reference-junction compensation, eliminating the requirement for an ice bath reference-junction
• Front panel switch selection of Fahrenheit or Celcius readings
• Switch selectable thermocouple inputs
• Overrange detection: Flashing display
• Open circuit detection: Source impedance of 3 kΩ or more causes a flashing "OC"
• Bright, high resolution LED display
• Leading zero compression 
• Switch selectable input line voltage  
• Can be run from ac line power or external 12 Vdc for field portability
