General Description of Spectrapak 309 Cooling Water Test Kit, Parameters; NITRITE, CHLORIDE & pH
Test recommended to maintain cooling water within the prescribed limits.
Nitrite - Recommended Limits can be in the range of 700-2400 ppm as NO2. Please refer to the inhibitor Product Data Sheet for product specific control limits. The nitrite concentration should be maintained within the above recommended limits to effectively inhibit any corrosive or scaling action within a closed cooling system. Too high a concentration should be avoided to minimize the cost to maintain the system. Insufficient dosage can set up a condition where accelerated corrosion can occur in areas which become unprotected.
