Mounted with the new R sensors, which are long-term consistence sensors

GX-3R mounted with the new R sensor series, which have dramatically improved the performance from the previous sensors. The sensors have 5-year warranty*.
*Option.

Wide range of safety functions

Combustible gas conversion function

Eliminates the need for complex calculations.
Allows direct readout of 26 different combustible gas types.

Lunch break

Enabling this function retains the TWA and peak values and allows integrating measurement whether power is on or off.

Alarm setpoints can be freely adjusted

You can now adjust alarm setpoints on the main unit.
Allows monitoring based on the customer’s own standards.

Cal. Limit

Indicates the number of days until recommended regular maintenance when the power is turned on.
Reminds the user to perform maintenance on the product to ensure safe use.

Confirmation beep

This function provides audible notification that the device is functioning correctly.
Buzzer sounds at preset intervals while measurement is underway.
