7 Technical data

Ambient conditions:

During operation –20 to 55 °C, for short periods up to 60 °C.
Between 55 and 60 °C the lifetime of the
EC sensors is reduced and the measuring
error is higher.
700 to 1300 hPa, 10 to 95 % r. h.
recommended ambient storage conditions for the device,
accessories and spare parts: 0 to 30 °C; 30 to 80 % r. h.
Degree of Protection IP 67 (with sensor membrane)
IP 54 (no sensor membrane)
Operating times at 25 °C in measuring mode:
with NiMH power pack up to 27 h with 3 EC sensors
4.8 V / 3.0 Ah up to 13 h with 3 EC sensors and 1 CAT
sensor
up to 9 h with 3 EC sensors, 1 CAT and
1 IR sensor or 1 PID sensor
typically more than than 7 h with 3 EC,
1 CAT and 1 IR sensor or 1 PID sensor in
pumped mode
with NiMH power pack up to 54 h with 3 EC sensors
4.8 V / 6.0 Ah up to 26 h with 3 EC sensors and 1 CAT
sensor
up to 18 h with 3 EC sensors, 1 CAT and
1 IR sensor or 1 PID sensor
typically more than 14 h with 3 EC, 1 CAT
and 1 IR sensor or 1 PID sensor in
pumped mode
54
with alkaline power up to 33 h with 3 EC sensors
up to 16 h with 3 EC sensors and 1 CAT

pack
sensor
up to 12 h with 3 EC sensors, 1 CAT and
1 IR sensor or 1 PID sensor
Required frequency of charging:
NiMH power pack 4.8 V / Every 3 weeks
3.0 Ah
NiMH power pack 4.8 V / Every 5 weeks
6.0 Ah
Alarm:
Setting range for alarm A1 > 10 ppb and A1 < A2
A2 > A1 and A2 < full scale value
Exception: For LEL-based units (%UEG,
%LEL, %LIE), A2  must be 60 %LEL
For the measuring range 0 to 5 Vol.-%
methane, A2  is 3 Vol.-
Acoustic alarm Multi-frequency tone
Volume >90 dB A (at a distance of 30 cm)
Pumped mode:
Maximum hose length 30 m for hose with an internal diameter of
4 mm; additional down time more than 12 s
45 m for hose with an internal diameter of
5 mm; additional down time more than 27 s
Volume flow max. 0.6 l/min
min. 0.2 l/min
