World’s smallest, lightest and most portable dry-wells
• Smallest dry-wells in the world
• Ranges from –10°C to 375°C
• Accuracy to ±0.25°C, stability of ±0.05°C at 0°C
• RS-232 interface

Fluke Calibration's line of portable dry-wells is incredible. They’re the smallest, lightest, and most portable dry-wells in the world. And now they're better than ever!

• Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected

• Continuous self-test so you always know it’s working

• Voltage detection range for wide application use - 90 V to 1000 V AC or 200 V to 1000 V AC

• Audible/Silent mode for added convenience

Key features
• Highly accurate, easy-to-use thermocouple temperature calibrator
• Measures and simulates 17 thermocouple types and millivolts
• Measures 4 to 20 mA signals while sourcing a temperature signal
• Comes with a magnetic hanger for convenient hands-free operation
• Features configurable source settings for quick linearity checks

A versatile and rugged tool for high current applications



Confidently take reliable readings with true-rms, Fluke 355 and 353 digital clamp meters; the tool of choice for high current clamp-on amp meter sizes up to 2000 A. The extra wide jaws easily clamp around large conductors, which are typically found in high current applications. The extra robust design and CAT IV 600 V, CAT III 1000 V ratings add an extra element of user protection when performing high power measures.



Accurate peak measurements are possible using the in-rush inrush mode, ideal for motor and inductive loads. The 355 also measures voltage and resistance, making it an ideal clamp meter for utility, electrical contractors and industrial service technicians.
