Commonly used instruments and equipment for detecting total coliforms, Escherichia coli, and fecal coliforms, along with a summary of laboratory routine configurations, can be directly used for laboratory inventory, acceptance, and procurement:

The enzyme substrate method is currently a simple, accurate, time-saving, and highly efficient analytical approach. Below we outline its methodological advantages and product features:

Enzyme Substrate Quantification Sealing Machine: Consisting of a programmable quantitative sealing machine, 51- or 97-well detection plates, 100mL quantitative bottles, and enzyme substrate detection reagents. Water sample detection scope: drinking water, source water, bottled water, reclaimed water

I. Temperature Malfunctions 1. Heating Roller Temperature Error: When the heating roller temperature display shows an error and cannot be correctly read, immediately restart the equipment.
