Advantages
| ・It can also be used as a conductivity meter for high concentration. |
|
・An alarm output for control is indicated on the large liquid crystal display as a measured value of concentration (weight%) in large numbers/characters. |
|
・On the same screen, the solution temperature, lower limit setting value, and the state of output are also indicated. The LCD is provided with backlight. |
|
・The meter is provided, as standard specifications, with contact output for alarm, voltage-applied output that enables direct connection of a pump, and pulse output for controlling an electromagnetic metering pump. |
| ・Current output (DC4 - 20ｍA) is also provided as standard specifications. |
|
・Changes in the setting values, calibration or correction of the measured value of concentration are done on the front panel. |
|
・A sunshade cover is included as the standard accessory, and the waterproof construction grade when the sunshade cover is fitted is IP54 or equivalent that allows the meter to be used outdoors. |
Applications
|
・Concentration control for chemicals such as hydrochloric acid and sodium hydroxide in the chemical industry, etc. |
| ・Incorporation of various process apparatus. |
| ・Salt concentration control for a scrubber. |
| ・Other control of solution concentration. |
