Product Description

Diffusion Type LCD Display Portable Ozone O3 Gas Detector


Portable Multi Gas Detector

1--4 Toxic Gas Detector




·It can be used in: rapid detection of a variety of gas concentration and measurement of environmental
temperature and humidity, if the measurement exceeded the limit value, the alarm will emit sound & light vibration as alarm.

·Adopted 2.31-inch high-definition color screen for real-time display, adopted the gas sensors of industrially well-known brands.

·The main detection principles include: electrochemical, infrared, catalytic combustion, thermal conductivity, PID
photoionization, and so on.

·Advanced electric circuit design, mature kernel algorithm processing, unique external appearance
design, had achieved a number of patents about the software works, external appearance, and so on.

·Suitable for detecting the concentrations of gases in the atmosphere environment in the pipeline or confined space.

·The purity of the gas leakage and various high concentration single gases with the background gas as nitrogen gas or oxygen gas. The types of gases for detection are more than 500 types.

1. Multi-gas made simple, easy to wear, slim and compact
It is possible to simultaneously detect 1 ~ 4 types of gases, and the units can be switched freely .
Units that can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/l.

2. Compact design, easy to use
Handy and durable, the MS104 is intuitive to operate single-handedly using three function keys.
The easy-to-read color display clearly lays out all the information for you. Thanks to its compact and robust construction, the device can withstand even the harshest conditions.

3. Large Data Storage Management, release and documentation in no time
Standard configuration is the data storage capacity for 100, 000 entries.
Real-time storage and fixed time storage are supported, or only the data of the alarm concentration will be stored.
It is supported to use the local host to view, and delete data, and upload the data via USB interface to the computer for data analysis or printing.RS485 communication is an optional configuration.

4. Clear signaling design
The signal system of the MS104K is based on a clear color code: sound & light alarm, vibration alarm, display screen visual alarm.These are also documented in the data logger.

5. Economical Calibration Management
The deviation of the concentration which was detected out by the instrument from the standard gas concentration can be corrected by calibrating the concentration or changing the display coefficients.

6. Inductive charging protects against wear and tear
The MS104K features inductive charging.
This makes it easier to operate and increases the lifespan of the device.
Issues like corrosion and contact problems in the charging cradle are a thing of the past. You can charge (outside of explosion-hazard zones) and measure at the same time.
