Portable speed measuring instrument pesticide residues genuine sea orientin Hing rapid detection of fruits and vegetables canteen hotels

Hangzhou Lu Hengsheng Technology Co., Ltd. is a research and development, production, marketing and related reagents water quality testing equipment business, based in Zhejiang University Huajiachi, has four-set. We have been in China water testing industry leader, our aim is to provide customers the most efficient, fastest, most affordable and most convenient testing services! This portable speed measuring instrument pesticide residue is based on the national standard method --- speed test card method (disk diffusion method) and specially designed equipment. Mainly for fruit, vegetables, tea, food, water, and soil organic phosphorus and carbamate pesticides rapid detection, especially for food safety inspection agencies at all levels of law enforcement to use the site, but can also be used tea production base and fruit and vegetable farmers wholesale market scene detection, and other security-speed measurement restaurants, canteens, before family fruit and vegetable processing. First, the instrument detection principle: SCM parameters of temperature and time control, with biochemical reactions to organophosphate and carbamate pesticides vegetables, fruits and other food products for semi-quantitative detection. Biochemical reaction principle: speed test card cholinesterase (white tablets) catalyzes the indophenol acetate (red tablets) hydrolyzed to acetic acid and indophenol, as organophosphate and carbamate pesticides on cholinesterase Inhibitory activity that catalyzes the hydrolysis of the color change after. Thus, according to the results of the color depth, you can determine the residual cases in the sample organophosphate or carbamate pesticides. Second, the technical parameters: 1, measuring the number of channels: 12 channels 2, constant temperature: 38 ℃ optional range: 25-45 ℃ 3, reaction time: 10 minutes Optional range: 0-99 minutes 4, coloration time: 3 min selectable range: 0-99 minutes Third, the instrument features: 1,12 channel, while rapid detection. 2, the equipment is small, light weight, without accessories, easy to carry. 3, quick operation, especially for field use. 4, built-in rechargeable battery, portable instrument to detect steps: 1. Press and hold the panel's power  key for about 2 s, instrument boot; press  button LCD display "temperature", when the preheating temperature After reaching 38 ℃, you can begin testing. 2, the installation speed test card and then fold unfold, tear the cover film, inserted into the channel under the heating platen rib plate (note the red pills end at the top, at the bottom end of white pills). 3, select a representative sample of leaves or fruit leather tip 5 g, placed in a small beaker with scissors about 1cm square pieces, add 10 ml of buffer or pure water, while doing a buffer or pure water blank control. Test on a sample with a pipette take 80ul was added speed measurement card of white pills. 4. Test Press  key, the reaction started the countdown 10min, [reaction] indicator light (note the instrument cover during the reaction should remain open); when you hear the instrument sends short beep tone close the cover, which was color automatically start the countdown 3min, [color] indicator light; the instrument is once again ease beep tone, then open the instrument cover, the result of determination. 5, and determines Compared with the control card, white tablet or slightly bluish discoloration results are positive, the same blue as the strongly positive results, indicating a higher pesticide residues, which was light blue weakly positive result, indicating the relatively low amount of pesticide residues. White pills into sky blue or with the control card the same negative result. The default configuration list: aluminum boxes, host adapters, certification, warranty cards, brochures, dropper, bottle, scissors, tweezers, speed test card HHX-SJ12NC portable speed measuring instrument pesticide residues steps a, power: The instrument-specific power adapter into 220V AC power outlet, the back of the instrument switch to the "on" state to boot, the interface displays the current temperature of the instrument. Tip: Press the "mode" button, point the reaction temperature , reaction time 10min, chromogenic time 3min] Second, the instrument to warm up: instrument is heated to a set temperature, a "bit" When prompted noise (usually beeps twice) Preheat complete, you can start the test. (Hint: ① instrument should be preheated open the front cover; ② prepare the sample) Third, install speed test card: the speed test card along the center line of the fold at the opened end of white pills transparent membrane, is inserted from the top of the instrument layering, then tear transparent film, check-speed measurement card is placed correctly. Tip: ① speed test card in the middle of the dotted line (broken line) should be aligned with the layering; ② red pills should be at the top; ③ white tablet should lie flat on the measuring tank heater; ④ the same way to install another piece of speed measurement card, as a blank matching] four, added: extraction test sample droplets join white tablet, then dropped in the blank with pure water or eluent white tablet (blank card by the reaction after blue color is showing no pesticide control standard color). Fifth, start measurement: Press the "start" button, the instrument displays and automatically begin the countdown time "10:00" reactive mind. [Note: At this point you can not close the front cover] Six color reaction: When the reaction time (reaction time 10 minutes), instruments issued a "bit" alert tone, then close the front cover instrument will display "3:00 "chromogenic timer and automatically start the countdown. Seven Results found: After the color of time (developer time of 3 minutes), the instrument sends a "bit" alert tone, open the front cover and result determination. The comparative speed measurement card white tablet color and standard color card (blank card) color. ① white pills into sky blue or with the control card the same negative results, indicating no or very low concentrations of pesticide residue; ② white tablet or slightly bluish discoloration results are positive, it indicates that pesticide residues and high concentrations. Note: The test is completed, carefully pull out the test card (preferably with scissors to cut the end of the test card red pills, drawn from the lower end of the test card), and wipe clean with a cloth or absorbent paper instrument heated place. Report: Change Settings Step 1, press the "mode" button, there is a small flashing triangle will point to the reaction temperature, reaction time, the color of time, select the option you want to change. 2. Press the "Settings" button, the "reaction temperature" flashes, press the "▲" "▼" button to adjust the temperature values, press the "Settings" button again to save and exit. (Press the "mode" button to exit without saving the settings) 3, using the same method to adjust the reaction time, the color of time. "National Standard GB / T 5009.199─2003 vegetables of organophosphorus and carbamate pesticide residues rapid detection" thermostat setting temperature 37 ℃, reaction time 10min, coloration time 3min. (Xiamen "Hai Hung Hing" brand HHX-SJ12NC pesticide residues speed measuring device we use the preset reaction temperature 38 ℃) This product is factory direct, free warranty for one year, within six months if non-human quality, free replacement.
