Memmert Humidity Chamber HCP50, 56 l, +18 to +90 °C, 20 to 95 % rh

With 56 litres of internal volume, the Memmert Humidity Chamber HCP50 is the smallest of the four HCP sizes. Internally it measures 400 x 425 x 330 mm (W x H x D, the depth is reduced by 35 mm for the fan), externally 559 x 795 x 521 mm plus 56 mm door handle. It actively controls temperature and relative humidity, in the setting temperature range from +18 to +90 °C and at 20 to 95 % rh, and there is also the rh-Off setting. Both control loops run via the ControlCOCKPIT TwinDISPLAY with two TFT colour graphic displays.

Humidifying, dehumidifying, supplying water

The water comes from an external container, and a self-priming pump delivers it into the chamber. An integrated germ barrier works with hot steam generation, and dehumidification is via a sterile filter. A water canister with connection hose is part of the scope of delivery. Only demineralised or fully deionised water with a conductivity of 5 to 10 µS/cm and a pH value between 5 and 7 is permissible. Anyone who wants to connect the chamber to the domestic water supply orders a central water supply with or without filter cartridges as an accessory, and the product information on it is available on request.

The setting accuracy is 0.1 °C for temperature and 0.5 % rh for humidity. Against condensate, all-round heating on six sides provides protection, plus the heated door and the heated rear wall.

Loading and housing

A stainless steel perforated sheet is in the interior from the factory, which is made of stainless steel 1.4301 (ASTM 304). Up to five shelves fit in, 15 kg per shelf are permitted and 75 kg for the whole unit. The net weight is approx. 55 kg, and the chamber is transported upright. A silicone feedthrough with 40 mm inner diameter sits in the rear wall (centre left), is humidity-tight and can be closed with a silicone plug.

Programs, timer and interfaces

Programs are programmed, managed and transferred via Ethernet or USB with the AtmoCONTROL software. The countdown clock with target time indication runs from 1 minute to 99 days. SetpointWAIT starts the process time only when the setpoint temperature has been reached. Three freely selectable values each can be calibrated for temperature and humidity. The temperature is displayed in Celsius or Fahrenheit, and the user interface is available in nine languages from German to Chinese. The chamber saves the program sequence in the event of a power failure.

Two sensors, AutoSAFETY and installation

Two Pt100 sensors of DIN class A measure in 4-wire technology. They monitor each other, and in the event of a fault each takes over the function of the other. The additional over- and under-temperature monitoring AutoSAFETY follows the setpoint at a freely selectable interval, reports deviations visually and acoustically and switches the heating off when exceeded. A self-diagnosis system helps with troubleshooting of the temperature and humidity control.

The HCP50 may be installed at 10 to 30 °C ambient temperature and a maximum of 70 % rel. humidity, non-condensing, up to 2,000 m above sea level. At least 15 cm distance to the rear wall is provided, 20 cm to the ceiling, and at least 5 cm at the sides to a wall or neighbouring unit.

Which size fits

Five shelves and 75 kg total load are the limits of the HCP50. If more is needed, the HCP105 with 107 l, six shelves and 90 kg is the next size. The HCP50 works from 7 °C above room temperature. If cooling or work below 20 % rh is needed, a different series helps: the ICH110 climate chamber with 108 l has a setting temperature range of -10 to +60 °C and controls humidity from 10 to 80 % rh in the range +10 to +60 °C. In return, it ends at +60 °C, whereas the HCP50 goes up to +90 °C and 95 % rh.

Typical applications

The HCP series is intended for these applications:

• Environmental testing
• Environmental simulations
• Accelerated lifetime tests
• 85/85 tests according to IEC 60068-2-67 and IEC 60068-2-78

Technical details

Other sizes in the series

The HCP series has four sizes with the same temperature and humidity range, sorted by internal volume:

Scope of delivery

• 1x Memmert Humidity Chamber HCP50
• 1x stainless steel perforated sheet
• Factory calibration certificate (measuring room centre of usable space) for 60 °C at 75 % rh
• Additional heated inner glass door
• Fully insulated stainless steel door with 2-point locking (compression door closure)
• Silicone feedthrough, 40 mm inner diameter, in the rear wall
• Water canister with connection hose

Regulatory information

The unit is an electrical device within the meaning of the German Electrical and Electronic Equipment Act (ElektroG). The WEEE registration number of the manufacturer Memmert GmbH + Co. KG is DE 66812464. Notes on returning old devices can be found on our page Environment and disposal.

Individual requirements and procurement service

Available as factory options for the HCP50 when ordering are, among others, 115 V connection voltage, lateral feedthroughs with 23 mm inner diameter left or right, 4-20 mA current interfaces for the actual value of temperature or humidity, a lockable door, a potential-free contact for fault messages and the SMS alarm MobileALERT. MobileALERT requires the alarm contact. Accessories include stainless steel perforated sheets and grid shelves, the central water supply, a USB-Ethernet adapter, a USB user ID stick, the FDA licence for AtmoCONTROL FDA, a stacking kit, base frames with 130 mm height or 622 mm levellable, and an external measuring device for temperature and humidity. Factory and DAkkS calibrations, IQ/OQ documents and short on-site training are also available. For individual requirements, we will advise you personally.
