0560 7351 735-1 Compact Pro Thermometer by Testo

The robust and compact measuring instrument with a probe socket for highly accurate Pt100 probes and two sockets for fast-action thermocouple probes. Readings from up to three additional temperature probes can be shown on the instrument's clear display; measurement data transmission is by radio i.e. wireless. A total of six channels can be collected in this way by the instrument. Using the highly accurate, plug-in Pt100 immersion/penetration probe, a system accuracy of 0.05 °C with a resolution of 0.001 °C is reached. The measurement system is therefore ideally suited for use as a working standard. Data measured by testo 735-1 can be transmitted by infrared to the Testo printer for documentation purposes. If cyclical printing is used, it is also possible to print data on the printer once every minute, for example.

• System accuracy up to 0.05 °C
• Testo printer prints measurement data on site (optional)
• Cyclical printing of readings once every minute, for example
• Displays, saves and prints Delta T, min, max and mean values
• Audible alarm when limit values are exceeded
• Protection class IP65
• Accuracy over the entire measurement range thanks to system adjustment

0555 6442 Compressed Air Flow Transmitter (1" line) by Testo

The compressed air counters testo 6441 to testo 6444 are designed for the measurement, monitoring and recording of compressed air consumption, and therefore also for the determination of leakages in compressed air systems, consumption-based allocation of costs and the implementation of peak load management. Using the compressed air counters testo 6441 to testo 6444, transparency of consumption is created for compressed air, similarly as for the media current, water or gas, thus increasing the motivation of those responsible for the process regarding cost reduction measures and energy savings. The compressed air counters testo 6441 to testo 6444 record norm volume flow according to the calorimetric principle, which means the measurement procedure is independent of the process pressure and does not cause a permanent pressure drop. While the thermal, glass-coated ceramic sensor offers a high level of robustness and fast response times, the integrated inflow and outflow pipes ensure optimum accuracy.

• Measurement of norm volume flow in the measuring range 0.25 to 700 m³/h (DN15 to DN50 or 1/2"-2"); consumption quantity in m³; media temperature in °C
• Highest flexibility thanks to different signal outputs: Analog output 4 to 20 mA (4-wire), Pulse output, 2 switch outputs (parameterizable: consumption or volume flow-dependent, opener, closer, hysteresis, window)
• Built-in totalizer, even without additional analysis unit
• Operating menu with LED display
