An input device is operated for importing at least a quantity of the fluid from a source. A filling device is instructed for filling a vial with a pre-determined amount of the imported fluid. A drawing device is operated for drawing a pre-determined amount of a reagent. The drawing device is activated for adding the pre-determined amount of the reagent to the vial. An output of a photocolorimeter is read. The output indicates a reaction of the pre-determined amount of the imported fluid and the pre-determined amount of the reagent. A result of the test is transmitted to a second computing system. ## Claims ### Claim 1 A method of testing a fluid sample comprising the steps of: receiving at least one instruction from a first computing system to schedule a test of a fluid; operating an input device for importing at least a quantity of the fluid from a source; filling a vial with a pre-determined amount of the imported fluid; operating a drawing device for drawing a pre-determined amount of a reagent; activating the drawing device for adding the pre-determined amount of the reagent to the vial; mixing the fluid and reagent in the vial; reading an output of a photocolorimeter, the output indicating a result of the reaction of the pre-determined amount of the imported fluid and the pre-determined amount of the reagent; transmitting the result of the reaction to a second computing system; and sending an order to another device to dose and correct for a missing chemical. ### Claim 2 (depends on 1) The method as recited in claim 1, further comprising the step of flushing the vial with a portion of the quantity of the imported fluid, before adding the reagent. ### Claim 3 (depends on 1) The method as recited in claim 1, further comprising calibrating the photocolorimeter. ### Claim 4 (depends on 1) The method as recited in claim 1, further comprising the step of activating a stirring device for mixing the pre-determined amount of the imported fluid and the pre-determined amount of the reagent. ### Claim 5 (depends on 1) The method as recited in claim 1, further comprising the step of transmitting the result of the photocolorimetric reading to a cloud server. ### Claim 6 (depends on 1) The method as recited in claim 1, wherein said reading occurs at a pre-determined time after mixing of the pre-determined amount of the imported fluid and the pre-determined amount of the reagent. ### Claim 7 A computer-implemented system for testing a fluid sample, comprising: a fluid testing input device for testing fluids, including: a system controller; a vial; a reagent dispenser; a mixer(s), and a photocolorimeter, a system controller configured to implement a test schedule receiving module, a communication module, a voice input module, a visual input/output module, a test method selection module, a reagent selection module, a reagent amount determination module, a wash cycle determination module, a rest time determination module, a data analysis module, a result generating module, an interface module and a heuristic module; a user device configured to communicate with the fluid testing input device over a communication network; a server device configured to communicate with the fluid testing input device and the user device over the communication network; wherein the fluid testing input device adapted to: receive a fluid sample into the vial from a predetermined source; dispense a reagent and mix the fluid sample and the reagent; test the mixed fluid sample and reagent in the photocolorimeter; generate a signal in/by the photocolorimeter for transmitting to the user device; wherein the user device is configured to, upon receiving the signal from the photocolorimeter, generate electronic instructions including pre-determined parameters pertaining to the fluid testing device, and transmit the instructions to the server; wherein the server device is configured to process the instruction received from the user device and send a control signal to the fluid testing device, thereby controlling the operation of the fluid testing input device based on the instructions from the user device. ### Claim 8 (depends on 7) The system of claim 7 further configured for operating a flushing device for flushing the vial with a pre-determined amount of the imported fluid. ### Claim 9 (depends on 7) The system of claim 7 further configured for calibrating the photocolorimeter. ### Claim 10 (depends on 7) The system of claim 7 further configured to activate a stirring device for mixing the imported fluid and the reagent. ### Claim 11 (depends on 8) The system of claim 8 further configured to initiate a photocolorimetric reading according to pre-determined time and time intervals.
