HT-2019 Enzymatic Substrate Method Programmable Quantitative Sealing Machine, Fecal Coliform Group Detection Instrument
Overview:
The HT-2019 enzyme substrate programmable quantitative sealing machine has been adjusted based on the original model HT-2017. The internal circuit has been moved to the top to prevent equipment short-circuiting due to leakage. The equipment baffles have been replaced with metal material to prevent damage from collisions. A one-button drainage function has been added, eliminating the hassle of manual cleaning of leaks by the operator.
HT-2019 Enzymatic Substrate Programmable Quantitative Sealing Machine for51-hole dosing dish and 97-hole dosing dishHeat-sealing function, compatible with U.S.ColitagMicrobial culture media usage, offering a 24-hour simple and accurate method for quantitative detection of total coliforms, Escherichia coli, and thermotolerant coliforms.51-hole and 97-hole dosing dishesBased on traditional methodsA semi-automatic quantitative method designed for the MPN statistical model, capable of quantitatively detecting water sample results, replacing filter membrane and multi-tube fermentation methods for detecting waterborne microorganisms.
Execution Standards:
Meets the "GB 3838-2002 Surface Water Environmental Quality Standard"
Meets the requirements of the "CJ/T 206-2005 Urban Water Supply Water Quality Standard"
Meets the "GB/T 5750.12-2006 Methods for Examination of Drinking Water Quality" standard
Meets the requirements of "DB21/T 2368-2014 Rapid Determination of Total Coliforms and Faecal Coliforms in Seawater by Enzymatic Substrate Method"
Meets the "CJ/T51-2018 Test Methods for Water Quality of Urban Sewage - Determination of Thermotolerant Coliforms by Enzyme Substrate Method" standard.
Meets the National Environmental Protection Standard HJ 1001-2018 for the Determination of Total Coliforms, Fecal Coliforms, and Escherichia coli in Water Quality
By data comparison: It can be observed that the enzyme substrate method offers a shorter detection time, does not require an aseptic laboratory, and has no specific professional requirements for the operator.
