Data logger for temperature and humidity for indicative measurement / Adjustable alarm limits / Micro USB interface / Measuring range 0 ... 1000 µg/m³ / Mass concentration / Approx. 9 hours of battery life / 3.2'' color display / Carrying case / 1/4'' tripod connection The data logger for temperature and humidity is used in offices, workshops or in laboratories to carry out indicative measurements of the environmental conditions. In addition to the number of particles, the particle counter determines the mass concentration of PM2.5 and PM10 in the measuring range 0 … 1000 µg/m³. In addition, the temperature and the ambient humidity are measured. With the alarm limit function, limit values for PM2.5 can be set on the particle counter. During a measurement it is possible to record the measured values with the data logger for temperature and humidity. A memory with a storage capacity of approx. 12 measurement runs, each with 999 measurement points, is available for the particle counter. The interval can be set at different times on the particle counter. After recording, the measurement data recorded by the particle counter can be transferred to a computer. The particle counter is connected to any computer via the micro USB interface to transmit the measurement data. Since the particle counter is recognized as a mass data storage device by the computer, the particle counter is independent of the operating system. The measurement data saved by the particle counter are saved in PDF. In addition to data transfer, the 8 Wh battery can also be charged via the micro USB interface. The battery used in the data logger for temperature and humidity enables an operating time of approx. 9 hours. Thus, the particle counter can carry out measurements over an entire working day before it has to be recharged. Since the battery is not permanently installed in the particle counter, it can be easily replaced. - Data storage for data logging - Adjustable alarm when limit value is exceeded - Transport case for safe transport - Suitable for indicative measurements - Measuring range 0 ... 1000 µm/m³ - Micro USB interface Specifications Mass concentration Measurable particle sizes PM2.5 / PM10 Measuring range PM 2.5 0 ... 1000 µg/m³ Resolution 1 µm Accuracy PM 2.5 0 ... 100 µg/m³: ±10 µg/m³ 101 ... 1000 µg/m³: ±10% of measured value Particle counter Measurable particle sizes 0.3 / 0.5 / 1.0 / 2.5 / 5.0 and 10 µm Resolution 1 µm Accuracy reference measurement Number of maximum particles 2,000,000 particles/L Temperature Measuring range -10 ... 60 °C, 14 ... 140 °F Resolution 0.01 °C, °F Accuracy ±2 °C, ±3.6 °F Humidity (RH) Measuring range 0 ... 100 % Resolution 0.01 % Accuracy ±3 % Further specifications Response time 1 second Warm up 10 seconds Mounting connection 1/4'' tripod connection Dimensions intake outside: Ø13 mm / 0.51'' inside: Ø7 mm / 0.27'' height: 35 mm / 1.37'' Display 3.2'' LC color display Power supply (mains adapter) primary: 100 ... 240 V AC, 50 / 60 Hz, 0.3 A secondary: 5 V DC, 2 A Power supply (battery) 3.7 V, 8.14 Wh, 18650 Battery life ca. 9 hours Interface Micro USB for charging and for data transfer to a PC Auto power off turned off 15, 30, 45 minutes 1, 2, 4, 8 hours Data memory flash memory for approx. 12 measurement runs a measurement run contains 999 measurement points Storage interval 10, 30 seconds 1, 5, 10, 30, 60 minutes Dimensions 222 x 80 x 46 mm / 8.7 x 3.1 x 1.8'' Weight 320 g / 11.2 oz
