Product Overview

H Series: H500 / H1000 

The H Series H500 & H1000 are saturated humidity cabinets which are designed to be simple and reliable to operate for your product testing.

The Alpha+ range by Ascott is designed for ease of use, simple operation and reliability. Easy to install with a minimal number of external service connections. Simple to operate due to intuitive touch screen interface. Reliable and uncomplicated design backed by 25 years manufacturing experience.

Design features:

  • Manufactured from a robust glass reinforced plastic (GRP) construction, combined with other non-corroding materials, to guarantee a trouble free long life.
  • Visually striking, transparent domed roof providing unimpeded 360 degree viewing of the cabinet interior.
  • Latching roof stay for ease of loading.
  • Self-regenerating water trap seal, preventing salt fog escaping during operation.
  • Ergonomically positioned menu driven touch screen programmer for comfortable and intuitive control.
  • Timed stop facility and hours run counter.
  • Maximised cross-sectional load area, enabling many samples to be tested at any one time, without compromising ergonomics.
  • Supplied with complimentary corrosion proof sample holders.
  • Platform available as an optional accessory for large/heavy objects to be located in the base of the cabinet.

International Standards Compliance:

The Alpha+ range complies with the most popular international standards for corrosion testing, including:

  • Salt spray standards
  • ASTM B117
  • ISO 9227
  • DIN 50 021
  • JIS Z 2371
  • Humidity standards
  • DIN 50 017-KK
  • DIN 50 017-KFW
  • DIN 50 017-KTW
  • ISO 6270-2
  • VDA 621-421
  • ASTM D2247
  • BS 3900 Part F2
  • All cabinets are CE marked as your assurance of their quality and compliance with European directives.



Key Features

  • Precise temperature controlled, high humidity environment. Water held in a sump located in the cabinet base is heated by an immersion heater to generate water vapour.
  • As water vapour evaporates, it saturates the cabinet atmosphere with moisture. Test samples in the cabinet, below the dew-point temperature of the saturated air, will develop surface condensation.
  • By careful design, the high humidity environment is achieved without the need for a circulation fan, which would otherwise have to endure the hostile, high humidity environment.
  • Safety cut-outs ensure the immersion heater is automatically isolated if the water reservoir runs dry.
  • The user can program either a single set temperature, or automatically cycle the cabinet temperature between two different temperatures for user defined periods of time.
  • Automatic filling and topping up of the humidity water reservoir if connected to a pressurised water supply.
