AFA sarl : Tous Echantillonneurs manuels de liquides / A complete range of manual sampling devices for liquids 

 

 
The DMA 35N portable density meter measures the density of liquids in g/cm3 or kg/cm3 according to the U-tube principle. 

The sample is inserted into the measuring cell using the built-in pump or a syringe. 

A temperature sensor measures the temperature of the sample in the measuring cell. The temperature is displayed on the read-out panel and at the same time used in the automatic calculation of density measurement as a function of temperature. 

Once the calculator is activated, the measured density value is immediately converted into density at the reference temperature (15°C). 

The DMA density meter has a storage capacity of 1024 measurement results, including temperature values.

The TP-7 has been developed for ease of use with its reel-case design. In addition to the case, the TP-7 is designed to provide very high reliability, less maintenance, an extended temperature range, and high accuracy without a higher price. This has been achieved by utilizing a platinum RTD temperature sensor, using low power programmable electronics, improving the packaging and integrating field proven components. Other hardware items include the stretch cord grounding assembly and reel locking mechanism.

To endure the environment, the TP-7 is manufactured of materials which are both immune to petrochemicals and are non-sparking. The enclosure is made of high impact plastic which dissipates static electricity and has proven to be tolerant to most petrochemicals, caustics or acids. As with all ThermoProbe instruments, the probe assembly is constructed with a very flexible static-dissipating, non-stick cable and stainless steel sensor components. To ensure longevity of the user interface the faceplate is fabricated of engraved aluminum plate, a scratch resistant polycarbonate window and an O-Ring sealed switch.

Operational Attributes:

Easily replaceable 9V Battery, provides an average of 50 hours operation. If probe assembly replacement is necessary, the terminals allow simple connection of the wires. Circuit logic automatically indicates low battery condition, shows readout integrity before each operation, automatically shuts off after two minutes and displays error codes for failure determination. The low power backlight for night operation is photo sensor controlled for convenience and battery conservation. Celsius or Fahrenheit units with C/F indication can be easily chosen by an internal selector without recalibration.
