With the compact temperature measuring instrument testo 925 (1 TC Type K probe, Class 1 included), you have the versatile solution for simple, fast and precise temperature measurements in industry and trade. The testo Smart App supports you with useful functions such as configuration, display (also as second screen) and storage as well as documentation of the measured values directly in the App.

Your advantages
• Easy, fast and precise temperature measurement with thermocouple Type K probe (1 TC Type K probe, Class 1, included)
• Fast in-app configuration, graph history, second screen and measurement data memory in the testo Smart App
• Wide range of applications due to large measuring range from -50 °C to 1000 °C
• Large probe selection optional and compatible with commercially available TC Type K sensors

The Fluke 1550C performs digital insulation testing up to 5 kV, and makes data collection easy through the Fluke Connect™ wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. It’s the perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur. And it comes with a three-year warranty and CAT IV 600 V safety rating.
Other useful features
• Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup
• Guard system eliminates the effect of surface leakage current on high-resistance measurements
• Selectable test voltages in 50 V steps from 250 V to 1000 V, and 100 V steps above 1000 V
• CAT III 1000 V, CAT IV 600 V safety rating
• Warning function alerts the user that line voltage is present and gives the voltage reading up to 600 V AC or DC for increased user safety
• Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall
• Long battery life gives the user over 750 tests between charges
• Large digital/analog LCD for easy viewing
• Capacitance and leakage current measurement
• Ramp function for breakdown testing
• Resistance measurements up to 2 TΩ
• Timer settings up to 99 minutes for timed tests
• 3-year warranty

Key Features
• Quickly configure, start and stop tests remotely, a safe distance away from any operating, energized equipment, using Fluke Connect® and a smart phone
• Real time trending gives you easy-to-see visual cues
• Report creation using Fluke Connect desktop saves time and makes test results easier to understand
• Fluke Connect saves test results to the cloud for analysis and preventive maintenance
