FEATURES
①It can be used in 24 hours continuous online monitoring of single
field gas concentration
and the types for detection are more than 500 types.
②There are 7 gas units to display, and the units can be switched
freely.
Units that can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb,
mg/l.
1.7-inch high-definition color screen, display the real-time
concentration, and alarm state.
①It is possible for the real-time monitoring via the wired or
remote wireless transmission, and network transmission.
②Three-wire system 4 ~ 20mA standard signal and standard bus RS485
(modbus-RTU) simultaneous output.
③It is possible to select frequency output 200-1000Hz, Hart
protocol signal, 1 ~ 5V output,
two-wire system 4 ~ 20mA, SMS alarm, wireless transmission (2 ~5 km
or unlimited distance).
④It is compatible with secondary instrument, data acquisition
module, PLC, DCS system,
and it is possible to drive the related equipment.
①Multiple alarm modes
Alarm types include: concentration alarm, and failure alarm.
Multiple alarm mode settings: low alarm, high alarm, interval
alarm, and weighted average alarm.
②Zero-point automatic tracking; long-term use will not be affected
by the zero drift.
③Multi-level calibration for target points, can ensure the
linearity and accuracy of the measurements.
④Log recording Record the calibration logs, repair logs, failure
history, failure countermeasure solutions,
sensor service life due reminder, and function of reminder for the
time of next concentration calibration.
⑤Data recovery function; in case of mis-operation, it is possible
to select partial or full recovery.
Standard configuration includes the infrared remote control, it is
possible for one-key operation via infrared remote
control function key, which can achieve the operation without
opening the cover under hazardous situations.
such as: the functions like modification of the alarm point,
density calibration, zero-point calibration, noise reduction,
restoring the factory setting, and so on.
■Integrated sound & light alarming device, split-type sound & light
alarming device,
■Wireless transmission
①It is possible to transfer data wirelessly to the cell phone,
remote monitoring center,
monitoring computers and other monitoring equipment, which will
utilize the upper-level host to realize
the functions of data analysis, storage, printing or the like on
the computer.
■ Pretreatment system
①Room temperature and high humidity pretreatment system
②High temperature and high humidity pretreatment system
③High temperature and high humidity and high dust pretreatment
system
■Installation type accessories
①wall mounting bracket;
②mounting clips for fixation on the pipes (1/2", 3/4" pipe);
③stainless steel threaded welding seat or flange to be installed on
the pipeline
(it is necessary to mark the flange or pipe size, such as DN50,
DN15 ...);
④Rain cover;
⑤24VDC or 220AC sampling pump (sampling distance is 10 m);
⑥vacuum pump (sampling distance is greater than 40 m);
⑦24V switching power supply;
⑧pressure reducing valve;
⑨flow meters.
APPLICATION
All the cases which requires the fixed installation, and online
detection of gas concentrations such as petroleum, chemical,
pharmaceutical, environmental protection, combustion gas
distribution, warehousing, smoke gas analysis, air governance, and
so on.
