We use this test kit to check our nitrite level in the water in our wood boiler. Using this test kit has always worked for us. Usually the powder comes in little foil packets this time the powder came in one bag with a little dip spoon. I feel the cost is too much but it is so necessary to keep your wood boiler in top shape.
