VACUUBRAND ME 4C NT Chemistry Diaphragm Pump Ultimate Vacuum 70 mbar (52 torr) Maximum Pumping Spee (more)d 2.6 cfm at 60Hz Number of Heads/Stages 2/1 Features - Outstanding chemical resistance - High performance even at low vacuum levels - Whisper quiet - Low vibration - Long diaphragm life, maintenance-free drive system Chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors. The one-stage construction provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. All major parts in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms increase reliability and extend operating life. The NT-series features further improved performance data, higher tolerance for condensates and simplified maintenance. The ME 4C NT is also available as chemistry vacuum system ME 4C NT +2AK with inlet separator to protect the pump against particles and liquid droplets, plus outlet separator to collect condensate. One-stage chemistry-design diaphragm pumps are an excellent choice for applications with corrosive gases and vapors which do not require very deep vacuum levels. They do not consume water and therefore do not produce any contaminated waste water. Typical applications are filtration as well as concentration of solvents with low boiling points. The ME 4C NT is recommended for processes which require higher flow rates. The chemistry vacuum system ME 4C NT +2AK with inlet separator and condensate catchpot is an excellent choice for rugged applications and for collecting condensates at the exhaust of the pump.INCLUDED: The VACUUBRAND ME 4C NT Chemistry Diaphragm Pump includes: - Power Cord - Operator's Manual - Manufacturer's Documentation - 2 Year Manufacturer's Warranty

The HX5.EX scale is a modern weighing instrument assuring fast and reliable measurement in hazardous (more) areas classified as zones 1/21 and 2/22. To ensure precision and excellent measurement repeatability, high quality electronic components are used. The weighing platforms offered in wide range of dimensions and maximum capacities, this combined with excellent metrological parameters enables easy selection of an instrument that meets the most demanding requirements. Standard version of the scale is equipped with 2 serial, intrinsically safe RS232 communication interfaces, and with one RS485 interface. They facilitate cooperation with equipment intended for operation in hazardous areas. Possibility to add digital inputs/outputs extends the range of instruments compatible with the indicator by automatic elements compliant with ATEX directive. More demanding customers can use the IM01.EX module, installed in the safe area, which extends the available connectors by Ethernet, USB, 4-20mA/0- 10V analog outputs, Profibus DP and additional digital inputs/outputs. This enables cooperation with external devices: barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. Scale operation requires use of a dedicated PM01.EX power supply, which is not a standard scale component. To operate the scale, order a selected type of the dedicated intrinsically safe power supply. Power supply types: PM01.EX-1 - power supply for operation in ATEX area. Used when it is required to connect the power supply to voltage source placed in hazardous area. PM01.EX-2 - power supply for operation outside ATEX area. Used when power supply connection to voltage source is carried out outside hazardous area. Complex software enables carrying out many tasks connected with mass measurement, e.g. parts counting, checkweighing and statistics. The scales feature user-friendly graphic interface, which can be customized using widgets. This and the large colour display of high resolution guarantee easy and clear transmission of data on current process. Colour bar graph significantly influences performance by signalling whether the weighing result is within declared thresholds or not. The frame for recessing (foundation) is part of the set – you will receive it with the ordered scale.
