Special climate meters

Laboratory kit with Pt100 probe for reliable and precise temperature measurement and documentation. Particularly suitable for use in corrosive media due to the laboratory probe, whose coating is made of the tried-and-tested DURAN^®laboratory glass. The testo 440 air velocity & IAQ measuring instrument automatically detects the connected probes, and the stored, structured measurement menus makes work considerably easier in a wide variety of applications. For example it can be used to optimally adjust air conditioning and ventilation systems.

• Structured measurement menu for long-term measurements
• Internal data storage and USB port for flexible data export
• Parallel connection of up to three probes possible: one Bluetooth^® probe, one wired probe and one temperature probe with thermocouple type K connection
• Versatile, expandable with an extensive selection of digital probes

Scope of supply: Climate measuring instruments, 3x AA batteries, USB cable and calibration protocol, glass-coated digital Pt100 laboratory probe, basic case for testo 440 and 1 probe
