Instrument Overview:

This instrument is capable of monitoring O2, CO, H2S, and combustible gases in various toxic and enclosed environments.

The highly tactile shell is made of high-strength impact resistant composite materials and can be used in various harsh environments. Meanwhile, the casing is resistant to electromagnetic interference and radio frequency interference. The simple and intuitive 4-point operation and calibration, as well as the 5-second shutdown function, can prevent accidental shutdown. The compact size and affordable price make it an ideal choice for personal testing devices.

In addition, the instrument also has vibration alarm, lithium-ion rechargeable battery, peak reading, large LCD screen display, 75 hour data recording and back clip. The optional gas sampling pump can achieve long-distance sampling, with a sampling distance of up to 50 feet.

Characteristics:

● Simultaneously detect 4 types of gases

Lithium batteries can work continuously for 18 hours

● Large LCD display

75 hour data recording, 50 foot remote sampling

Performance parameters:

Sensor configuration: M40 has 1, 2, 3 or 4 gas configurations to choose from, including oxygen, hydrogen sulfide, carbon monoxide (electrochemical sensors), combustible gas/hydrocarbons (catalytic combustion sensors)

Range:

Display: The large LCD screen can simultaneously display the concentration readings of four gases. Large fonts, high contrast characters, graphic symbols, and unique amber background lights provide clear visibility in low light environments.

Alarm device: vibration alarm, 90 decibel and super bright indicator light sound and light alarm. High/low concentration alarm, short-term exposure limit alarm, time weighted average alarm, and low battery level alarm. When used in conjunction with the SP40 pump (optional), a flow alarm indicator is also provided.
