Portable acidity meter/pH meter

PH value tester:

Acidity is one of the important parameters in the food industry. There are personal and cultural differences in taste, and considering storage resistance, it is necessary to closely monitor the acidity of food. Acidity not only affects the taste of food, but also the growth ability of microorganisms such as bacteria and fungi. The accuracy of acidity measurement will assist you in pursuing and improving food safety.

Generally speaking, the higher the acidity of food, the less susceptible it is to microbial corrosion. For example, the dangerous and well-known microorganism in food is Clostridium botulinum, which produces various toxins and has caused countless human deaths. Acid helps to inhibit bacterial growth, allowing commercial food processing companies to utilize hot canning processes without the need to reach temperatures above 121 ℃. This greatly reduces the cost of filling.

Acidic foods rely on one or more food acidifiers to achieve a stable state, such as citric acid, malic acid, or acetic acid. From ancient times to the present, we have been utilizing the properties of acid to preserve food. Usually referred to as acid washing. Acid washing is a process of preserving food by anaerobic fermentation in saltwater to produce lactic acid, or by storing food in acidic solutions such as vinegar. It is said that this technique originated in India 4000 years ago, where local cucumbers were soaked to make "pickled vegetables".

Performance:

1. Portable single channel and dual channel instruments with IP67 waterproof, data storage, infrared interface, and extended GLP support are ideal choices for regulated industries with special requirements or for measuring under conditions.

2. Conventional instruments used for single channel and dual channel measurement, with IP67 waterproof and data storage functions, are an ideal choice for high-quality performance instrument applications.

A portable instrument with a protection level of IP54 and data storage function has introduced a low-cost mobile measurement tool for the field of electrochemistry, making it an ideal choice for customers with limited budgets but still in need of reliable instruments.

4. Portable dustproof and waterproof EL2 and EL3 instruments are suitable for on-site testing.
