Soil Drying Ovens
Laboratory Ovens
UTEST Laboratory Ovens have been designed for the drying asphalt, soil, rock, concrete, aggregate or similar materials. Various litre capacity models are available. The ovens have a temperature range of ambient to 250°C. The interior of the ovens is manufactured from stainless steel and the exterior has been created from sheet steel and finished in powder coated paint.
All models are fan circulated (forced convection), fitted with a direct reading digital control unit and equipped with an analogue over-temperature protection thermostat. All ovens are supplied with 2, 3, 4 or 5 shelves, according to the capacity.

Muffle Furnaces
The UTD Series Muffle Furnaces are used for determining various properties of construction materials. The various furnaces cover a temperature range of 1100°C to 1600°C. They are all front loading for easy operation and have been designed with a double skin to provide a cool outer case.
The furnaces include a PID digital control system which allows for temperature control. The vertical counter balanced door opens in an upward movement and has been designed that way to avoid the hot insulation reaching the operator. When the door is opened, the power is isolated by the safety switch.

Freezing and Thawing Chamber
UTD-1440
The Freezing and Thawing Chamber is used to measure the resistance to freezing and thawing.
A sensor is placed either in the sample, in the water which the sample is placed into or, in the salty water solution placed on the sample before starting the test. The temperature of the chamber is then controlled by the sensor. The calibration of the sensor can be carried out using the user friendly menu.
An integral fan is used to distribute the temperature within the cabinet.
The chamber is equipped with a user defined program including 10 steps. Time can be adjusted to 999 minutes for each step of the program. The temperate in the cabinet can range from -30°C to +30°C.
Data can be monitored during tests, and data transfer to a computer is achievable through software supplied with the cabinet. The data can be converted to an excel report or to a graph.
The condenser of the cabinet is fitted with an air cooled hermetic cooler. The gas used for the cooler does not include CFC’s.
The control unit is electronic and equipped with digital display with 0.1°C temperature resolution. The temperature distribution accuracy in the cabinet is not higher than 2°C.
The user can preset the time of each ramp and the number of each set by using the control unit.
