校准解决方案
电导率标准溶液和pH缓冲液用于水质测试仪的工厂校准。建议定期使用这些溶液，以确保仪器的精度。电导率重新校准的频率取决于实际使用情况，但对于每天使用的仪器，每月一次就足够了。pH型号的仪器，根据使用情况，应每1-2周使用pH 7缓冲液重新校准一次，并以类似的间隔使用pH 4和/或pH 10缓冲液进行检查。

442 Natural Water™ Standard Solution is NIST Traceable and is used in calibrating many test instruments. It is the best choice when measuring boiler and cooling water samples, city water supply, lakes, wells, etc. "442" refers to the combination of salts mixed with deionized water to comprise this standard: 40% sodium sulfate, 40% sodium bicarbonate, 20% sodium chloride. A combination of standard salts is necessary since natural water salt type and concentration can vary greatly by location.

ORP Standard Test Solutions by HannaORP standard solutions allow you to test the precision of ORP electrodes. For example, by immersing the electrode in HI 7020 solution, you should read within the 200 to 275 mV range (@20°C/68°F). If the reading is outside the indicated interval, clean and condition your ORP electrode in HANNA® pretreatment solution.
