Water chemistry

Grallert

Hello. here I am again. I need to order a water chemistry test kit. My system is a two pipe steam pumped return system of about 95Ksqft. Two steel horizontal firetube Pacific Steel boilers. For years we've tested about once a month our selves and our chemical guy comes twice a year. Our kit has become useless and I'm wondering if you all have any suggestions for a new kit. What should we be testing for etc. Thanks for your input

Rhomar had a great manual for hydronic and steam boiler treatments, I have a copy on an old computer, I’ll look for it tomorrow.
The test kits are usually intended for the specific treatment chemicals

Ph, tds, hardness of the fill water can be easily tested with meters available online
