The Nano SPY U is the all-rounder in the Nano SPY range. The data logger has a universal input for Pt-100 (3-wire), current (4...20 mA / 0...20mA), voltage (0...1V), pulse, or dry contact / potential-free contact. This makes it possible to also read in 'foreign manufactured' transmitters, for example. Think of pressure transmitters (for clean rooms), CO2 sensors for incubators or an alarm contact of a filling robot.
See the manual for the various connections. The logger is equipped with internal display and 3 alarm LEDs (green, blue, red). The Nano SPY works +/- 6 years on one lithium battery and has a memory for 10,000 measurement points. Optionally available with a COFRAC (primary ISO 17025 certificate) or traceable calibration.
