Product overview
YA-D400 series point type gas detectors are widely used in
chemical, petroleum, metallurgy, liquefied gas stations, painting
operations, gas transmission and distribution and other toxic,
combustible gas generation, storage, use and other indoor and
outdoor easy to leak dangerous places.
YA-D400 series point type gas detector is a practical and easy to
operate gas detector developed by our company. It can be combined
with our gasalarm controller YA-K series to form an industrial gas
alarm system.The product adopts wall-mounted (can also hold the
tube type, scaffolding type, ceiling type) installation, through
the use of the controller, and through the controller single chip
microcomputer to upload the data of the gas detector for a variety
of data processing, and finally complete the data display, output
control and other functions.
Functions
1. Displays the concentration of the detected gas.
2. Fault alarm, high and low alarm.
3. Field screen display, including backlight, the word is larger
and clearer, and the backlight turns red when the device alarms.
4. Infrared remote control input, no open cover operation, more
convenient.
5. Support three different sound and light output, corresponding to
fault, low report, high report.
6. Zero, calibrate, test function.
7. Output DC4-20mA standard signal.
8. Support RS485, two buses, LoRa, flexible communication mode.
9. High performance ARM microprocessor for easy operation.
10. Three relay (250V 5A) output, automatically open the fan and
solenoid valve.
11. Can store 40 high and low alarm records.
12. Toxic gas detector can achieve mg/m³ and μmol/mol conversion.
