Finger Print Test Chamber

The fingerprint testing chambers from Weiber are designed to accelerate ninhydrin, DFO, and other fingerprint development processes for faster detection of fingerprints. They provide optimum conditions of high temperature and high relative humidity for accelerated fingerprint development processes, while maintaining astonishing clarity and higher throughput. Unlike the conventional methods that may even require days before processing of results, the Weiber Finger Print Development Chamber are capable of processing fingerprints quite rapidly and the results can be obtained within a few minutes. These equipments offer a wide temperature and humidity range and use microprocessor based controllers for highly precise control of operating parameters for highly accurate and stable working conditions, ensuring reliable and repeatable results. The unit ideally operates at 80�C and 65% RH for fingerprint detection using ninhydrin and at 100�C for detection using DFO. Both ninhydrin and DFO work by reacting with the amino acids present in the fingerprints and are commonly employed for fingerprint detection on porous surfaces such as unpainted wood and paper.

The Weiber Finger Print Test Chamber are available as both independent floor standing models as well as smaller bench top models. They are available in various capacities to accommodate a wide range of samples and usually come equipped with a flexible shelving system to allow simultaneous processing of large batches of samples.

Features:

• Speed of development and accuracy of controlled conditions:. The controlled conditions of high temperature combined with high relative humidity accelerate the Ninhydrin process, yielding excellent clarity in just three minutes
• High quality steam generator for active humidification and faster heating
• Vertical LED light strip to provide an illumination area, allowing visual monitoring of the fingerprint development process.
• Designed to maintain a vertical airflow, preventing condensation on the surfaces and accumulation of moisture that can adversely affect the quality of prints.
• The exhaust air and vapours are vented outside through the top mounted exhaust unit or the fume hood.
• Equipped with a steam generator that ensures faster heating of the chamber while maintaining the humidity levels for quick ramp-up time and rapid recovery upon door openings.
• Further options: A water recirculation system can be fitted to the FDC for users who require a demineralized water supply.
• Colour touch panel.
• HMI+PLC in one unit
• Door open and Door close alarm system.
• Inbuilt calibration system.
• Separate Inbuilt printer for printing graphs(optional).
• Cfc Free Refrigeration Unit:
• Less use of Electrical and Mechanical Components on the Top and Bottom of Chamber - Provides easy maintenance of chamber, increases durability because of proper air circulation; cooling systems kept at bottom of the chamber to provide proper environment for compressor.
• Full opening door with silicone gaskets and hinged on left side - Allows ease of complete access to the chamber and opening of door with less force; durable silicon gasket reduces temperature loss.
• Heated Vewing Window - Heated viewing window allows viewing fog generated and proper viewing of the test sample.
• Circulation Fan with Variable Speed -
  
  • Electrical efficiency
    Variable speed motor saves money by reducing energy bills, as it consumes less electricity than conventional motor.
  • Cooling Efficiency
    Variable speed enables gaining air conditioning efficiency or SEER.
