At the BePositive trade fair, Testo will be introducing its two latest measuring instruments to professionals: testo 860i and testo 558s

This major event brings together all professionals involved in the energy transition. At this event, the manufacturer will unveil its latest innovations designed for climate engineering experts, including the testo 860i connected mini thermal imaging camera and the testo 558s electronic manifold, equipped with a 4-way valve block and an intuitive touchscreen.

Small but extremely practical, the new testo 860i connected thermal imager for smartphones with connection to the testo Smart App perfectly meets the needs of professionals in the heating, air conditioning, sanitation, building and maintenance sectors for carrying out spot checks (heating inspection, leak location, hot spot identification, humidity visualization, etc.).

It provides all the information needed to easily determine the delta T (temperature difference) in the thermal image precisely and quickly thanks to the application-specific measuring functions: . DeltaHeat for evaluating the difference between the flow and return temperatures of radiators, . DeltaCool for indicating the differential temperature of refrigeration and air conditioning systems.

The "Thermography" measurement function quickly and easily displays hotspots and delta T for maintenance, while the "Humidity Mode" helps assess the risk of mold growth in rooms. Thanks to the camera's high infrared resolution (256 x 192 pixels) and thermal sensitivity (50 mK), the images are very sharp.

The testo 860i smart camera is operated, the thermal image and differential temperature are displayed, and documentation is carried out simply and intelligently on a smartphone or tablet via the testo Smart App. The testo Smart App allows you to export images and create and send reports in PDF format.

The testo 860i offers flexible operation either via one-handed operation with direct attachment to the smartphone or tablet, or separately up to 10 m from the mobile device. Finally, its robustness (IP 54 and fall protection up to 1,5 m) and the rechargeable LI battery with long battery life make the testo 860i a reliable tool that is easy to use in everyday life.
 

testo 558s, the electronic manifold with 4-way valve block and intuitive touchscreen

The latest generation of the manufacturer's electronic refrigeration pressure gauges, the testo 558s, boasts new features that allow air conditioning and refrigeration engineers to work intuitively from a smartphone or tablet via the testo Smart app. Combining precision, connectivity, and ergonomics, it has been designed for all demanding refrigeration professionals.

Thanks to the touchscreen and the large color display with clearly structured visualization of the measured values, the testo 558s can be set up, operated, and documented quickly and easily. The instrument can be fully operated via the testo Smart App or via the glove-friendly keys for precise operation.
To facilitate everyday use of the testo 558s, measurement results are displayed in clear graphs and now as 30-minute trend curves. Guided menus guide the user step by step through the measurement process and enable the automatic determination of all important system parameters such as superheat, pressure drop monitoring, vacuum, etc. All data and measurement results are centralized in the testo Smart App for easy documentation and reporting by email.

The testo 558s electronic manifold connects via Bluetooth to the entire range of refrigeration devices (testo Smart Probes, current clamp, vacuum pump and fluid scale) to control them from the numerous menus installed on the device.

With over 96 refrigerants included and automatically updated, compatible with the increasingly widely used flammable refrigerants of classes A3 and A2L, the testo 4s electronic manifold with 558-way valve block guarantees maximum safety.

The high measuring accuracy of 0,25% full scale (60 bar) and the integrated temperature compensation guarantee maximum precision even at low pressure.

Finally, the testo 558s is always ready for use thanks to the hybrid charging system comprising an accumulator (ISB-C) and batteries.
