test

Augmentation of the speed of temperature change to 2 °C/min in the temperature range of 0 °C to +80 °C.

Humidity Options

For all applications requiring an exact setting of the air humidity, the ultrasonic atomization in combination with the dehumidification methods is the best choice. The ultrasonic dehumidifier is separated from the explosion-proof test room by means of a zone separation valve. The desired humidity can be preselected by means of the electronic PID-controller, which is integrated in the Control2015 touch. Dehumidification is realized by condensation at a special plate heat-exchanger.

The dehumidification is realized by condensation or freezing of the water vapour contained in the air at a plate heat-exchanger of stainless steel in special design. Periodical hot gas defrosting thaws the frozen water, which will be dripping into the condensate drain.

Extension of the minimum humidity range to 10 % relative humidity up to a minimum temperature of +20 °C.

Extension of the minimum humidity range to 10 % relative humidity up to a minimum temperature of +20 °C by means of dried compressed air of the customer.

Ion exchanger for direct connection to the drinking water pipe, if demineralized water supply is not available.

Canister for water supply at installation places without water connection.

Light Options

LED lighting of the test room by two vertically arranged LED bars. Individual mixing of the red and blue components of the spectrum is possible by means of the option multichannel light control.

Appliances with LED lighting in several levels are the best choice for plants with low growth height. They distinguish by optimum economy of space.

The multi-channel light control allows control and dimming in groups of LEDs of different lighting levels and light spectra. Program-controlled change of the light spectrum is possible.

CO2 Gassing

As 4th module, the CO2 gassing allows examination of the short- and long-term effects of the so-called "CO2 manuring effect" on plants of categories C3 or C4. The CO2 sensor is equipped with a multi-position CO2 and temperature adjustment, which is a guarantee for outstanding measurement accuracy. Due to the NDIR two-beam method, the sensor is insensitive to soiling, and ageing effects are compensated automatically. Furthermore, the CO2 sensor has an excellent long-term stability and auto-calibration.

Optional Accessories

Their maximum carrying capacity is up to 25 kg.

The reinforced stainless-steel grid shelves are recommendable for building material testing or beer forced-ageing tests. Their maximum carrying capacity is up to 50 kg.

The triple glazed glass panel door always ensures an optimum view into the test room. A pane heating avoids formation of condensate.

Another option: the internal glass door. When the appliance door is open, it allows a visual check of the specimen - without any unnecessary disturbance of the climate in the test room.

The stainless-steel plate evaporator is always recommendable, whenever acid resistance is required, such as for Drosophila cultivation.

A 45 mm duct in the lateral panel allows insertion of measuring lines and hoses into the test room. Delivery including cover.

Gas-tight closing plug, matching to the tubular port. The gasket system with a flexibility in the range of 4 mm to 23 mm is based on a rubber module with removable skins and can be adapted to the cables, tubes etc. in different sizes.

2 Fresh air rosettes, air flow rate adjustable, located in the upper and lower area of the test room, ensure the fresh air supply into the test room. Application: Plants, test animals

Mobile version of the test cabinet with 4 steering rollers, 2 of them lock-type with brake.

Test room socket for connection of shakers, magnetic mixers etc. in the test room. Switching-on times can be freely programmed by means of the CONTROL2015 touch.

Electromagnetic door release by means of the CONTROL2015 touch. Door unlocking only after successful authorization with entry in the logbook (name, date, time).

Collecting pan for dew water or condensate. It can be easily withdrawn to the front.

Convenient application: A self-controlling heating rod ensures automatic evaporation of the condensate. Thus, periodical emptying is not required.

Export execution for power supply 110 V/60 Hz.
