High Performance Temperature & Humidity Test Chambers

High Performance Temperature & Humidity Test Chambers

Product Description

High Performance Temperature & Humidity Test Chambers are suitable for both constant temperature / humidity and temperature / humidity cycling applications. Special attention has been given to achieving an evenly distributed airflow. This ensures consistent conditions throughout the chamber volume and therefore more meaningful test results. Standard chambers are available with two temperature ranges, using single stage or cascade cooling plant, and with the choice to increase ramp rates through boost heating and cooling
options. The Touch Screen Programmer makes it easy to set-up and monitor the chamber conditions, and is particularly useful for simplifying the programming of complex cycles. The chambers are attractively styled to blend in with modern production and laboratory equipment and available sizes cover a volume range from 216 to 1500 litres.

Humidity Control

The High Performance Temperature & Humidity Test chamber is designed to accept a wide range of humidity control options to enable a variety of steady state and cyclic damp heat tests to be performed. Close control of temperature/humidity conditions is achieved by means of an electronic microprocessor controlled dual loop programmer. An elechumidity charttronic capacitive humidity probe is fitted as standard for high reliability and minimum maintenance. Humidity generation requires a supply of de-ionised water. This may be supplied from a local reservoir or automatically from a mains supply, where available, via an optional de-ioniser unit. Chamber condensate is normally re-circulated to minimise water consumption,
but may be drained at programmable intervals if required.

Construction

The inner chamber is fabricated from high grade stainless steel for corrosion resistance and easy cleaning. All internal joints are seam welded to ensure a vapour tight construction. The mild steel outer cabinet is attractively styled and has an easy to clean epoxy paint finish. Dense mineral wool insulation blankets the entire chamber to ensure energy efficient operation. Full access to the interior is gained through the hinged front door. This has a double sealing arrangement, pressurised by the door catch, to prevent moisture ingress at low temperatures.
Powerful fan(s) are used to ensure low thermal gradients and uniform testing of products. The fan motors are mounted outside the chamber for maximum reliability.The refrigeration plant consists of a single stage or cascade system (depending on temperature range), and is generously sized for long term reliability. Anti-vibration mounts and vibration eliminators minimise noise and vibration.

Touch Screen Programmer

All High Performance Temperature & Humidity Test Chambers now come with our latest Touch Screen Programmer at no extra cost. The Touch Screen Programmer enables the temperature (and humidity where fitted) to be easily programmed and displayed on the test chambers. The touch-screen window gives a clear, user-friendly interface with a constantly updated display of the current set and actual values for temperature and humidity. Touch Screen Programmer uses only commercially available components to ensure low cost of ownership over the lifetime of the chamber.
