| Ex-MX4 BT - Intrinsically Safe Thermometer
For contactless temperature monitoring and data storage in the device afterwards, or rather transmission to a PDA using the integrated Bluetooth function.
Features:
- Quick response time: 250 ms
- Laser circuitry provides measurement mark diameter
- Up to 100 measured values can be stored
- Data can be transmitted to a PC using the integrated Bluetooth interface
- Measure from Zone 1 into Zone 0
The Ex-MX4 BT is the first choice for monitoring temperatures on objects which are difficult to access or for moving materials. The precise and robust measuring instrument measures 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 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. Furthermore, the device has a High / Low alarm function which signalises exceeding or falling below a measured value threshold acoustically or visually.
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!
