Measuring system

Open measuring system without absorbent parts and with two parallel arranged electrodes for simultaneous recording of negatively- and positively-charged air ions

Measuring scope

Air ions with a ion mobility of 1.3 cm²/Vs (small ions) and more. Air ions with lower mobility are partially detected.

Ion polarity

Positively charged air ions and negatively charged air ions at the same time

Flow rate of sample air

24.5 l/min per channel, via integrated fan

Measuring ranges

Eight measuring ranges from 0 ... 1000 ions/cm³ up to 0 ... 40,000,000 ions/cm³, automatic measuring range switchover

Zero-offset adjustment

Automatic zero-offset adjustment via servo-driven lock, configurable after switching on and in freely definable time intervals

Starting time

Min. 30 seconds, typically: 15 minutes

Ambient temp.

Operation: 0 ... 40 °C,
storage temperature: -10 ... 0 ... 50 °C

Display of measured value

Numeric display on backlit LCD display (240 x 128 pixels)

Temperature / humidity

Optional detection of temperature and humidity with integrated sensor in the air channel

Storage of measured values

In CSV format (date, time, max., min., and floating mean of each polarity) on an internal SD memory card (256 MB), starting time, duration and storage interval all freely definable. Recording of measured values via integrated FTP server and PC software (included in delivery)

Self-monitoring

Battery voltage, fan speed; optical and acoustic (switchable) fault message

Analogue outputs

One output per channel 0...10 VDC / 0 ... 20 mA, lower and upper limiting value definable, both outputs are galvanically separated by the measurement device.
Voltage output: min. input resistance of the follow-on device: 10 kOhm
Current output: max load resistance of the follow-on device: 400 Ohm

Battery operation

Integrated NiMH battery pack, 12 V / 3 Ah, for 6 hours operation with charged batteries

Charger

Super-fast charger 1.8 A with an input voltage of 100 to 240 VAC inc. Euro power cable, charging time: approx. 3 hours

Mains operations

With plug-in power supply 12V DC / 800 mA with an input voltage of 100 to 240 VAC inc. plug adapter for EU, USA, UK and Australia

Device connections

Recessed on rear of device:
Charger / power supply: 2.1 mm low voltage plug (positive terminal on the centre tip),
Serial port: 9-pin SubMinD socket,
Analogue outputs: 9-pin SubMinD plug,
Network: 8-pin RJ45 socket
Charge balance: 4 mm socket for discharging possibly linked fields and electrical charges

Device configuration

Partially directly via 5 touch keys, otherwise with PC software (included in delivery) for Microsoft Windows via serial interface, German and English operator guidance

Housing

Anodised aluminium profile housing, 2 tripod sockets UNC 1/4 inch (photo) and UNC 3/8 inch (microphone)
