Model:
HA-98CO
Real time
monitoring CO level with range from 0 to 1000ppm
LCD can display CO, temperature and humidity at
the same time.Full time monitoring CO level,
even the slightest leak can be detected.Can only
working as transmitter of CO, but also working
as the controller of CO.Providing 0～10V analog
signal and 2 relay dry-contact outputs.Analog
output with two alternatives: linearized over
full range output or PID control output.Preset
the first, second CO alarm points
Semiconductor sensor technology with long
lifetime
RS – 485-communication interface, 15 KV
antistatic protection, independent address setup
PC/ABS top grade flame retardant housing |

0~20000ppm .LCD can display LPG concentration
with temperature and humidity at the same
time.Real time monitor LPG in detecting area in
all day, even light leakage
Also as concentration transmitter of LPG or as
the controller of LPG, fire and alarm.RS-485
communication interface, 15KV antistatic
protection, independent base address setting.
PC/ABS flame retardant housing.Providing 0～10V
analog signal and 2 branches relay dry-contact
output.Analog output of linearized relevant to
LPG level .Optional one relay which can be
adjustable trip point according to second alarm
point

Model: HA-98D CO2 and toxic
gas detector
Multiple functions, high performance, low
price, make it praiseworthily.Real-time
detecting and LCD displaying CO2 concentration,
temperature and %RH .Non-Dispersive Infrared
Detector (NDIR)15 years lifetime of CO2 sensor
.Also as transducer of CO2 or as the controller
of CO2, temperature and humidity.Microprocessor
control and programmable logical control.RS-485
communication interface, 15KV antistatic
protection, independent base address.Providing
0~10V analog signal and relay dry-contact
output. Analog output with two alternatives:
linearized over full range output or PID control
output.Optional on board relay with field
adjustable trip point according to CO2,
temperature or humidity (programmable
selection).
Locale adjustable range CO2: 0~20,000 ppm or
0~50,000ppm； temperature: 5~45℃；humidity：5～95％RH
ABC Logic with patented Self Calibration
Algorithm makes end users use it for 15 years
without calibration amending. That is suitable
for where concentrations will drop to outside
ambient conditions (about 400ppm) at least 3
times in a 14 day period
