รายละเอียดสินค้า เครื่องวัดค่า Conductivity meter - BI-680 Online Dissolved Oxygen Controller
BI-680 Online Dissolved Oxygen Controller
Economical online dissolved oxygen controller, 1 or 2 points calibration, 4 to 20mA signal output. The meter is used for monitoring the dissolved oxygen concentration and percentage saturation in the water.
Features:
• Economical online dissolved oxygen controller is equipped with a polarographic sensor.
• 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
• Manual salinity and barometric pressure compensation improve the measurement accuracy.
• Automatic Temperature Compensation ensures accurate reading over the entire range.
• Low and high alarm limits can be set by user and automatically activate an external device.
• 4 to 20mA output signal meets industry standard.
• System menu allows setting the 10 parameters, including the number of calibration points,
measurement unit, alarm limits, hysteresis value, etc.
• Reset feature automatically resumes all settings back to factory default options.
