Before using any pH meter, it must be calibrated with pH standard solutions to measure the pH of samples. Due to the wide variety of pH meters from different brands and manufacturers, their calibration steps and methods may vary slightly, but they are generally similar. Without targeting a specific product, let's discuss the calibration methods and steps for pH meters overall. For general applications where high accuracy is not required, a single-point calibration method can be used. Industrial online pH meters typically employ a two-point calibration method. For laboratory-grade instruments, a three-point calibration method can be used.

A sound level meter is an instrument that measures sound intensity and is widely used in environmental protection, noise control, sound quality assessment, and other fields. To ensure the measurement accuracy and reliability of the sound level meter, it needs to be calibrated regularly. This document will introduce in detail how to calibrate the sound level meter.

A salinometer is a valuable tool for measuring the salt concentration in various solutions, especially in oceanography, aquaculture, and water quality monitoring. To ensure accurate and reliable salinity measurements, periodic calibration is essential. In this blog, we will guide you through the process of calibrating a salinometer, covering calibration standards and different calibration methods.

Temperature and humidity data loggers are widely used in various industries across the country, such as agricultural scientific research, food safety, pharmaceutical storage, chemical industry, environmental protection and other industries. The temperature and humidity recorder is mainly used for monitoring and recording the temperature and humidity of food, medicine, and fresh goods during storage and transportation. Below we will introduce the function of the temperature recorder, the operation steps and how to calibrate it.

Before using the pH electrode, it is very necessary to perform numerical calibration on it. The pH electrode calibration method refers to a method to make the measurement results of the pH electrode more accurate and reliable through a series of operations. Its main steps include cleaning the electrode, calibrating the electrode and judging whether the electrode needs to be replaced.

This carbon dioxide meter from SISCO combines CO2 detection and smoke alarm in one and can be used for air quality monitoring with a detection range from 400 to 5000 ppm. In addition, it can also provide real-time temperature and humidity data, allowing for full knowledge of your surroundings. Keep in mind when you purchase the unit you have to calibrate it first. And we’re here to help you with that. In this video, we’re gonna show you how to calibrate our CO2 meter.
