Continous measurement of gases, that exhibit the properties of absorbing infrared energy (e.g. carbon dioxide)
Typically used for the measurement of carbon dioxide over the range of 0–5000 ppm to 0–100 Vol. %.
Processes, in which the moisture content in the gas can be as high as 95% rel. humidity, for example:
Monitoring composting processes in environmental technology
Process gas monitoring in the food and provisions industry
Food storage houses
Monitoring fermentative processes in fruit processing
Laboratories
and many more
features:
-section keyboard and illuminated 4-line LC-Display for displaying actual values, half-hourly average values and fault messages in cleartext
Operation, fault and alarm indications on LED's
Menu-assisted setting of the equipment parameters via the 6-section keyboard
Three separate alarm thresholds, referred to average value or instantaneous value; adjustable hysteresis
Data memory for alarm and fault messages
3 floating relay contacts for alarm signalling
Floating change-over contacts for faults, acoustic (horn) and optical warning (warning banners)
RS 232 / RS 485 connection for communication with
a PC or for controlling a printer
4-20 mA current interface
Plastic wall housing IP54 / straightforward installation
Extremely reliable, easy maintenance. Washable measurement chamber with replaceable dust filter
Available with an integrated test gas feed pump (optional)
External unterruptible power supply (optional
