Anton Parr DMA 35 EX portable density and concentration meter
DMA 35 is a portable density and concentration meter that you can take along for quick quality checks directly on-site.
The intrinsically safe DMA 35 Ex is suitable for measuring the density or concentration of flammable or explosive chemicals in hazardous areas. The instrument with Ex-marking II 2 G Ex ib IIC T4 considerably contributes to a safe working environment.
Your sample is filled directly from the sample container into the measuring cell using the built-in hand pump. Within seconds your DMA 35 shows the measured result on the large display.
Via the integrated RFID (Radio Frequency Identification) interface, samples are identified wirelessly within a second. By scanning an RFID tag attached to the respective sample container, the sample name and measurement settings are automatically changed for the following measurement.
With its robust housing, DMA 35 is built to withstand the knocks and spills of outdoor use.
DMA 35 EX Features:
- Explosion-proof design – Secure handling of explosive and flammable samples: The product version DMA 35 Ex is intrinsically safe.
- Quick sample identification via RFID – The DMA 35 Ex identifies samples wirelessly via radio.
- Reliable technology from the market leader – More than 45 years of experience in digital density measurement based on the oscillating U-tube principle are packed into the heart of your DMA 35.
- Built-in convenience – DMA 35: measures, calculates and corrects the temperature influence. You: read the final result off the large screen.
- Intuitive operation – As soon as you hold DMA 35 in your hands, you will know how to operate it, without any explanation.
- Wireless data transfer (IrDA) – No more cable tangles – printouts and data exports are performed wirelessly via infrared.
