The Fluke 50 Series II contact thermometers offer high accuracy with fast response times to quickly capture your measurement and show trends. Choose one of the four models to get functionality, thermocouple support and data logging you need.
• Laboratory accuracy: ±(0.05% + 0.3°C)
• Large, backlit dual display for easy reading
• MIN, MAX, and AVG -with time references- captures major events
• Electronic Offset function allows compensation of thermocouple errors to maximize overall accuracy
• Supports a wide range of thermocouple types
• Readout in ºC, ºF, or Kelvin (K)
• Splash and dust resistant case protected by impact absorbing holster
• Sleep mode increases battery life; typical 1000-hour battery life
• Battery door allows easy battery replacement without breaking the calibration seal
