Intrinsically Safe Temperature Meter for Zone 1 & DIV 2 - Ex-MX4 BT
The precise and robust measuring device measures the temperature in a non-contact manner, even in Zone 0.
The sighted measuring area can be very clearly recognized 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.

Product Description
Operation could not be easier: sight on the object, press the measurement button and read the measured value. Measuring data can be stored directly in the device or transferred to a PDA.
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!
