Product Description

BH-90A portable single gas detector can make continuous detection to combustible and toxic gases. It is suitable for combustible and toxic gas leakage detection in underground pipe or mines, and keeps the workers safe, prevents the facilities from being destroyed.The detector, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and reproducibility. The detector adopts embedded MCU controller, easy to operate. The shell adopts special high strength material and anti-smooth rubber, with the characters of water-proof and dust-proof.

Main Function:

Alarm method:

1.Low alarm:Short slow alarm tone;The alarm indication is yellow;The red alarm light flashes;Device vibrates .

2.High alarm:Abnormal harsh alarm tone;The alarm indication is red;The red alarm light flashes;Device vibrates.

3.Low battery alarm:

When the device is in low battery, it will give slow short alarm every minute to remind user.

Alarm Record:Enter alarm record interface, display date and max alarm value, it save the max alarm value every 3 minutes.Zero function setting:it is to ensure that the operation is carried out in clean air, otherwise the concentration of the reaction gas in the environment will affect the accuracy.Gas calibration setting:Input the standard gas value.inject standard gas, once the value is stable after 2 minutes,press “SAVE” calibration is done. The rate of flow 500ml/min is recommended.Time setting:After set year,month, date, hour, minute,Press“SAVE”to complete the time set.Unit set:Enter “Unit set” choose the unit(PPM/mg/m3)and save it.

Feature:

Advanced MCU control with low power consumption;Adjustable low and high alarm level;Adjustable calibrating level;High concentration protection;Self test for the gas sensor;Low battery indication;Self- adjustment function;

Visual,audible and vibration alarm;Advanced self-examination and self-renovation function;Password management to avoid wrong operation;Explosive proof housing.
