Measurement range VOC:	0-100% (good / bad air quality, referring to the calibration gas)
Scales:	0-200/500/1000 ppm
Accuracy:	CO: ±5 ppm + max. ±5% f. mv VOC: ±15% FS; Humidity: ±3% r.H. (30...70% r.H., else ±5% r.H.); Temperature: 0,5 K (15...35°C, else ±1 K); Air pressure: ±5 mbar; all specifications at 20°C, 45% r.H. 1013 mbar, auto-calibration ON;
Temperature dependency:	CO: ±5 ppm / K, Humidity: ±0,04% r.H. / K; Temperature: ±0,1°C / 10 K
Long term stability:	±1% FS/year
Sensor:	CO: electrochemical sensor; VOC: metal oxide sensor; Humidity/Temperature: capacitive humidity sensor
Sensor protection:	sinter filter, mounted inside housing
Supply voltage:	24 V AC/DC (±5%)
Current consumption at 0-10 V:	Ø 100 mA
Current consumption at 4-20 mA:	ca. 200 mA
Analogue output 0-10 V:	3-wire connection
Analogue output 4-20 mA:	3-wire connection
Alarm output:	1 x potential-free change-over contact, 48 V, 1 A
Switching Hysteresis Relay:	0,02
Electrical connection:	screw terminals max. 1,5 mm²
Display:	LCD display with backlight
Automatic calibration:	To ensure an excellent long-term stability, in the interval of ca. 20 days (VOC) starts an automatic recalibration. Through this automatic calibration possible drifts are compensated. This feature can be disabled on the device by DIP switch.
Initial operation:	After switch-on of the device follows a self-test and the tempering, which takes ca. 10 minutes depending on the environmental conditions. At this time the analogue output drifts from the actual measurement value.
Cable gland:	M16x1,5 high-strength cable gland with strain relief
Housing:	ABS housing with hinge closure, colour light grey like RAL 7024
Dimensions:	Housing: L 150 x W 80 x H 62 mm
Protection type:	IP65 (housing), IP54 (probe)
Protection class:	III
Working range r.H.:	0...98% r.H. in contaminant-free, non-condensing air
Working temperature:	0...+50°C
Manual calibration:	The manual calibration of the output signal to 1 V (VOC zero point) will be started by pushing the button on the circuit board (push ca. 5 s until "CAL" appears in the display). Before this it is to ensure a non-stop operating of min. 10 minutes on fresh air. After successful calibration "CAL" disappears from the display.
Storage temperature:	-20...+50°C
Installation:	screw fastening
Approvals:	CE, EAC, RoHS
