Nitrate Reagents (100 tests)
The HI93728-01 reagents are used for the colorimetric determination of nitrate on compatible benchtop and portable meters.www.hannainst.com

Yes, I've been very impressed with mine too. Sad that I have to retire it for a while LOL.Well I got my checker with the 10 packets, I have been using salifert, salifert I was getting about 50ppm but it’s hard to tell. Hanna confirms at 48.6ppm! Love it! Will have to wait for more reagents.
Fish only btw![]()
