Abstract

The invention provides a continuous indicator strip 10 having a multiplicity of separate individual sequential test sections 12 along the surface thereof, wherein a plurality of said test sections are impregnated with the same indicator enabling the utilization of said strip for sequential repetitive testing of samples, said strip being provided with at least 20 such test sections.

Claims

AMENDED CLAIMS received by the International Bureau on 17 MAY 2006 (17.05.06)
1. A device for automated monitoring of the chemical characteristics of a body of water, said device comprising a housing containing: a) a continuous indicator strip having a multiplicity of separate individual sequential test sections along the surface thereof, wherein a plurality of said test sections are impregnated with the same indicator enabling the utilization of said strip for sequential repetitive testing of samples, said strip being provided with at least 20 such test sections in combination with a dispenser for holding and feeding said strip; b) a take-up spool electrically driven for drawing said strip from said dispenser; c) a liquid feed outlet above the path of said strip in combination with a solenoid-operated valve for sequentially dispensing drops of sample liquid from said body of water onto said indicator strip; d) an electro-optical sensor positioned to detect color changes in said test sections occurring as a result of contact with a. drop of said sample liquid; e) a controller unit connected to said sensor for noting and recording said changes, and f) a fluid circuit having an inlet positioned within the water of said body of water, a minor outlet connected to an inlet of said solenoid-operated valve, a major outlet, and pumping means to circulate said liquid in said circuit.
2. A dispenser for use in a device according to claim 1 containing a plurality of continuous indicator strips each having a multiplicity of separate individual sequential test sections along the surface thereof, wherein a plurality of said test sections are impregnated with the same indicator enabling the utilization of said strip for sequential repetitive testing of samples, said strip being provided with at least 20 such test sections, and adapted to simultaneously hold and feed said plurality of strips adjacent to each other in a path below said liquid feed outlet in order to enable the utilization of said plurality of strips for sequential repetitive testing for various chemicals contained in a 11
plurality of drops simultaneously delivered on each of said plurality of adjacent strips.
3. A device according to claim 1 wherein said strip is provided with at least 20 such test sections, wherein a plurality of columns of said test sections are provided side by side, each column being impregnated with a different indicator enabling the utilization of said strip for sequential repetitive testing for various chemicals contained in a plurality of samples delivered at each of said test sections.
