Measuring Instruments ALMEMO® V7 Data logger ALMEMO® 202-S and ALMEMO® 204 ALMEMO® data logger Professional measuring instrument of the latest V7 generation. Two or four measuring inputs for all digital ALMEMO® D6 and D7 sensors, for ALMEMO® standard sensors with the DIGI measuring range. ALMEMO ® devices can be used for a variety of applications, examples: Monitoring the indoor climate conditions: temperature, air humidity, CO2 level, air flow. Measuring the illumination and the UV exposure at the workplace: illuminance in lux, UV index. Mobile measurements in ventilation systems: air velocity, temperature, air humidity. Meteorological station with meteo multi sensor and radiation sensors: air velocity, wind direction, temperature, air humidity, atmospheric pressure, global radiation, UV radiation, UV index. Monitoring temperatures in test stands and in industrial processes: temperature, non-contact measurement (infrared sensor). Mobile test measurement in heating furnaces and climatic chambers: temperature, air humidity, dew point, absolute humidity. Measuring the quality of deionized process water (ultrapure water): electrical conductivity in the lower range of few µS/cm. Test measurement of process water and waste water in industry (i.a. chemistry, pharmacy, paper, food): pH value, redox value, electrical conductivity, temperature. Test measurements in compressed air systems: fast pressure measurement (up to 500 mops), dew point measurement (residual moisture). Measuring AC and DC voltage signals with high galvanic isolation: voltage/power/output DC (up to 1000 mops), true RMS value AC.

Data logger of the latest V7 generation The professional measuring instrument ALMEMO® 202-S and ALMEMO® 204 provides numerous outstanding functions for special applications using digital ALMEMO® D6 sensors and the latest ALMEMO® D7 sensors. Two or four measuring inputs for all digital ALMEMO® D6 and D7 sensors All new digital ALMEMO® D6 and D7 sensors for a wide variety of measurable variables can be connected and evaluated. ALMEMO® standard sensors with the DIGI measuring range can also be used, e.g. for crossflow turbines and high-voltage modules for thermocouples, and DC and AC voltages. The ALMEMO® 202-S and ALMEMO® 204 supports all ALMEMO® functions. New digital ALMEMO D7 sensors With these digital ALMEMO® D7 sensors the ALMEMO® system is enhanced by many new functions and applications. ALMEMO® D7 sensors operate via an all-digital interface to the ALMEMO® 202-S and ALMEMO® 204 data logger ensuring high-speed serial transmission of all measured values. The measuring ranges of ALMEMO® D7 plugs are independent of the ALMEMO® measuring instrument being used and can be ® expanded as and when required for new applications. Measured values can be displayed with up to 8 digits (depending on range) and the units with up to 6 characters. Sensor designation and information can be up to 20 characters. Each ALMEMO® D7 sensor has its own processor. They all work in parallel at their own sensor-specific sampling rate. D7 sensors thus attain very high measuring speeds in dynamic measuring operations. The ALMEMO® D7 plug can process up to 10 channels for measured values and function values. This includes new applications, especially for multi-purpose sensors (e.g. Meteo sensors) and for linking up to complex third-party devices (e.g. chemical analysers, power analysers). Digitize and calibrate the existing sensor technology Using the ALMEMO® D7 input plugs the existing sensor technology can easily be digitized. For digital sensors the overall accuracy of the measurement is independent from the ALMEMO® V7 display device / data logger. The complete measuring chain, consisting of sensor and connected ALMEMO® D7 measurement plug, can be calibrated. The accuracy during the calibration process can be increased by usi
