The new ALMEMO 2470 series meter are a real high - tech - all rounder and can be used for numerous applications, i.e. as climate or laboratory instrument data logger or display device for alarm monitoring. The units are available with or without data logging facility. When digital sensors are connected they will provide highly accurate measurements, i.e. for temperature, humidity, pressure and carbon dioxide. The calibrated sensors can be exchanged on any of the devices. Sensor extensions have very high noise immunity. There are no additional errors in the transmission of measured values, as may be the case with analogue signals. High precision Factory or DKD calibrations of the sensor elements can also be performed independently of cable or instrument. Accurate correction of the readings can be made against the reference values. Therefore highly accurate measurement can be made with zero error. The measured values are clearly displayed on a colour display. The units offer features such as Max - Min , alarms, zero setting, sensor display, sensor correction, data logger functions, and other parameters such as cycles, real time clock or sleep mode. A dual display is available for the simultaneous display of two measured values or measured value and alarm value.
