01 / Product explorer

Six models.
One place to compare.

Filter by the sensing method shown in MANORSHI’s current catalog, then open a model page or email the team about it.

Need a datasheet? Start an inquiry ↗

Only specifications visible in the live product titles and listing appear here. Electrical, environmental and performance details require the current datasheet.

Clearer selection. Better inquiry.

The right question today makes the right sensor easier to find tomorrow.

02 / Selection path

Turn your requirement
into a model discussion.

Use these three inputs to make the first conversation specific enough for engineering and purchasing.

STEP 01

Target gas

Choose from CO2, CH4, CO, H2S, O3 or Cl2. Ask about O2 or another gas if it is not listed.

STEP 02

Measurement range

State the normal and maximum concentration in ppm, % volume or % LEL.

STEP 03

Integration context

Share output, supply, environment, size, quantity and the equipment using the sensor.

03 / Gas sensor applications

Gas sensor applications

Start with the gas, then describe where and how the sensor will operate. These application illustrations are selection examples; confirm model suitability against the current datasheet.

CO2

HVAC and indoor air quality

Define the ventilation control range, installation point and output interface.

Illustration of methane monitoring around an industrial gas pipeline
CH4

Combustible gas detection

Share the gas type, LEL range, alarm threshold and installation environment.

04 / Questions

Before you send the RFQ.

Which target gases are listed?

MANORSHI’s current category page lists CO2, CH4, CO, H2S, O3 and Cl2 models.

What do NDIR and electrochemical mean?

NDIR senses infrared absorption. Electrochemical sensors use a reaction at electrodes. The target gas and operating conditions guide the choice.

How do I decide on the detection range?

Provide the normal operating level and the highest concentration your device must measure. Confirm the chosen range against the model datasheet.

Which outputs are available?

The MNS-QT331 methane listing specifies UART. Request current datasheets for the other models and tell the team your required interface.

Can I request a sample?

Include the model, intended test, project stage and quantity in the inquiry so the team can confirm availability.

Can specifications be adapted for OEM use?

Describe the range, interface, housing, connector or calibration requirement. MANORSHI can confirm what is supported for the selected model.

Is O2 available?

An O2 model is not listed on the current category page. Send the target range and application to ask about availability.

What should a quote request include?

Include target gas, range, application, quantity, company and contact information. Output and environmental details help further.
