製品概要：
The online hardness analyzer is an online water quality monitor with a microprocessor. The instrument is equipped with a calcium ion concentration electrode and is used to monitor industrial water, domestic water, wastewater and some calcium-containing water.
The instrument uses an LCD display screen; intelligent English menu operation; has current output, free setting of measurement range, high and low limit alarm prompts and three sets of relay control switches, adjustable hysteresis range; automatic or manual temperature compensation; multiple automatic calibration methods for electrodes.
According to user needs, calcium ion electrodes with various installation type such as [flow-through], [immersion], [pipeline] and [flange] can be provided.
Structural features:
The whole measuring system mainly consists of two parts: the controller (secondary instrument) and the industrial calcium ion electrode (primary meter). The industrial calcium ion electrode contacts the measured aqueous solution, and the controller displays the calcium ion concentration value and temperature value of the aqueous solution and the working status.
応用：
Tap water industry: Real-time monitoring of the hardness index in tap water to ensure that the tap water quality meets national or local standards and ensure the safety of drinking water for residents.
Environmental protection: Monitor water hardness, assess water pollution in rivers, lakes, reservoirs and other water environments, and provide data support for environmental protection and governance.
Drinking water treatment plant: During the drinking water treatment process, the water hardness of the raw water, the treatment process and the effluent is monitored in real time to ensure that the effluent quality meets the drinking water standards.
