KASTE - Real estate humidity measuring and leakage control

Isn’t water there where it should be ? Do you want your property to remain dry and avoid mold at your building?

KASTE – humidity measuring and leakage control system detects when water is going to a wrong place.

Indoor air problems are commonplace in new and old buildings. The origin of the problem is often mold fungi which lives at moist structures. Moisture can enter the building in many ways: the roof can leak, drainage ditches flood, water pipes may leak and bathroom fixtures break. Even in new houses moisture can remain in the building materials during the assembly or concrete floor does not dry out because of a construction error.

The KASTE system includes two kinds of humidity sensors. The system has two types of humidity sensors: KASTE, in which all sensors are wired to the same network and LOGGER-KASTE, in which humidity sensor also includes an independent, battery-powered data logger. It provides 1000 measurements with a standard 9V battery (PP3) and saves sensor data to SD memory card at user specified time interval for later analysis with a computer. KASTE - measurement system monitors the humidity level of your property and gives alarm signal, if necessary. System humidity sensors measure air relative humidity of the concrete floor, external walls, ceilings etc.

Alternatively we offer LEAK-KASTE which monitors leakage problems. Leak sensors indicate water leaks, for example, below a dishwasher and washing machine. The LEAK-KASTE and KASTE sensors are wired to the same network in series, which makes it very reliable in comparison with systems operating in battery power - and wiring costs are minimized at the same time.

In the control program each sensor has been given a moisture limit, above which the main unit triggers the alarm sound while a relay switches on an alarm in the building automation system. At the same time a signal lamp turns on at the corresponding sensor on a touch screen. Additional options include a 3G connection, SMS alert and internet software that enables the measurement to be followed on any internet-connected computer or mobile device.
