Time Selector Unit for Continuous Flow Injection Techniques ( TSUCFIT)

The presented unit aims to use previously chosen by the researcher time setting(seconds or minutes ) that can be controlled for the purpose of what  is going to record of signals or responses from instruments output used for the purpose of scientific researcher or applied industrial scientific uses; apart from the of the use of the presented unit in automation processes i.e.; performing many automatic process in one go. The unit does not uses any kind of detector or probes  whatever the kind is , but it uses many resistances and one single capacitance fixed in a way to have the specified timing that unit gives .As there are five preselected timing (95,126,181,231, and 318 seconds ) chosen by the researcher and by the use of a selector . In addition to the five timing selections there is OFF position that will separate electronically the unit from the attached instrument that were in an ON position for the purpose of adjustment of attached instruments. The unit can be loaded by 5-12 amperes. The attached instruments e.g.; chemiluminescence ,fluorescence  and absorption spectrophotometer will be as low as 1 ampere for example 0.125A for the x-t potentiometric recorder .The presented unit characterized by the presence of PUSH bottom with the capability of repeating the previously selected timing by the researcher without any numerical timing , only a press on the push button and the design will ensure that.
