field audio and visible alarm

simple installation

excellent reliability & high stability

self test fuction,Auto-reset

Durable sensor head.

less affected by other organic solvent.

high accuracy.

Low-battery indicator:

one "chrip" every 30 seconds with green LED flashing and "Lb" on the LCD.

Mal-function indicator

one "chrip" every 30 seconds with green LED being out and "Err" on the LCD

CO sensitivity & alarm time:  300ppm→ alarm within 3 mins.

100ppm→ alarm wihtin 10-40 minss

                            50ppm→ alarm within 60-90 mins

(Note:CO density is 30-999ppm,the LCD will show its actual concentration, or "999ppm" after exceeding 999ppm.)

Memory feature:

if the unit ever alarms,pressing the button,green LED flashes and peak co figures on the LCD.

(Tips:3 minutes preheating to enter into work mode after connecting with battery.)

advantage:

1. memory function               

2.LCD displayer show actual co concentration

3.Test & reset button

4.sensor: 5 years life

5.CE & EN50291
