PN4500 hydrogen sulfide concentrationanalyzer

* High precision imported technology sensor
* Sensitive sense of smell and fast response speed

1Overview
PN4500The series hydrogen sulfide gas analyzer has many advantages such as fast response speed, good stability, high sensitivity, small size, light weight, and easy portability. Simultaneously equipped with a gas sampling pump, the measurement results are faster and more accurate. Widely used in fields such as environmental sanitation, industrial production, smoke and exhaust environmental monitoring, sewage treatment, biopharmaceuticals, home environmental protection, laboratories, etc.

Multiple functional interfaces ＆ Faster measurement

2Function Description:

* The sensor adopts imported brand gas sensors with world-class level (including infrared principle, photoionization principle, electrochemical principle, catalytic principle, etc.)
*Safety reminder: The lighting and alarm sound can reach up to 90 decibels, and the linked alarm switch output is available
* Using large capacity lithium rechargeable batteries, it can be charged for 1 hour and work for 8 hours, and can work continuously for a long time
*Large screen digital LCD backlit display, human-computer interactive dialogue operation, simple and intuitive, more convenient.
*The upper and lower limit alarm values can be set arbitrarily, with built-in zero and target point calibration functions, outstanding audio and sound alarms, ensuring that dangerous gas concentrations can be detected even in extremely unfavorable working environments and prompt operators to take preventive measures in a timely manner
*The shell is made of special materials and processes, which are not easy to wear and tear, easy to clean, and bright as new after long-term use
* Equipped with standby power-saving mode, flexible control of sampling pump start stop operation, achieving ultra long standby.
