Pesticide residues Speed ??Tester pesticide residue pesticide prices detector detector manufacturers Ou Keqi OK-C6 + microcomputer pesticide residues Speed ??Tester according to organophosphate and carbamate pesticides can inhibit the central and peripheral nervous systems of insects active enzyme acetylcholine , resulting in the accumulation of neurotransmitter acetylcholine, affecting the normal conduction, this insect insect toxicology poisoning principle, be used in the detection of pesticide residues. If the extract does not contain vegetable or lower organophosphorus or carbamate pesticide residues, the enzyme activity is not inhibited, the test substrate was added to produce enzymatic hydrolysis, the hydrolysis products of color developing agent reacted with added color. Conversely, if the vegetable extract contains a certain amount of organic phosphorus or carbamate pesticide enzyme activity is suppressed or partially suppressed, the test can not be added to the enzymatic hydrolysis of the substrate are partially hydrolyzed or less, so as not to little change in the color or color, absorbance was measured using a spectrophotometer to calculate the inhibition rate changes over time, you can determine vegetables contain residues case organophosphorus or carbamate pesticides. Features a multi-channel testing technology, Ke simultaneous detection of multiple samples. 2, using a large-screen LCD backlit display, Chinese boot operation. 3, AC and DC [automotive and lithium battery (optional)] dual,? Built-in high-capacity battery, can work for four hours in a row in the absence of an external power supply. 4, LED lamp as a light source, a silicon semiconductor as a signal receiving system, long life of 100,000 hours. 5, built-in thermal printer, store print? Test results. 6, with the test results are automatically saved and can save the query records. 7, with a response time setting and the eligibility criteria set. The host can automatically determine whether the test results were satisfactory. 8, can be connected to a computer can also be used alone, can send data and reports data sharing through the Internet or a local area network, and has storage, collection, processing and evaluation functions. 9, built-in water bath, automatic control incubation time and temperature. 10, through GPRS module, the data wirelessly to your phone and computer network (optional).
