Intrinsically safe Non-Contact Temperature Meters Ex-MX2 / Ex-MX4 BT

For non-contact temperature measurement and monitoring of temperature processes
in Ex-hazardous areas.

The Ex-MX2 and Ex-MX4 BT are the first choice for monitoring temperatures on objects which are difficult to access or for moving materials. The precise and robust measuring instruments measure the temperature without contact, even in Zone 0.

Operation could not be easier: sight on the object, press the measurement button and read the measured value. The sighted measuring area can be very clearly recognised using the 3-point measuring area marking, and the device can be adjusted and matched to the most diverse materials using the emissivity setting (in 0.01 increments). An exact measurement result is obtained in this way. The device has a ‚High' (the Ex-MX4 BT also a ‚Low') alarm function which signals the exceeding or falling below of a pre-set value
threshold.

Only Ex-MX4 BT:
The values determined can be stored internally (space for 100 measuring spots) and called up on the display afterwards by pressing a button.

Using the integrated Bluetooth function, the data can be transmitted to an intrinsically safe PDA directly in the ex-hazardous area and/or to a PC with integrated Bluetooth interface outside the ex-hazardous area.

The user can select settings such as minimum and maximum value display and difference and average value calculation using the menu buttons.

If the emissivity of a material is unknown, it can be determined using the included measuring sensor. However, this function is only allowed outside the ex-hazardous
area!
