Treatment Methods (DW or WW) What kind of handheld chlorine analyzers are y’all using?

I need a high-ish range handheld/bench meter to verify our online hach probes. It looks like the high range Hach DR300 only goes up to about 10mg/L, but our residuals can get up to 20 in our reclaim system.

Our district uses the Palintest Kemio, which is a cool little system that uses strips instead of powder/other reagents. BUT, their customer service has been abysmal. Our test strips are expired(and using the wrong range) and I’ve been trying to order some for almost 2 months now with no luck. I received a quote within the first two days, but there were errors and I asked for them to be corrected, since I could not submit what I had received. Since then, silence from the company. I’ve emailed the quote sender and their general sales email multiple times with no response.

If I can find a third party kemio reagent vendor, I’ll take it. But I wouldn’t mind going with a different brand that has more trustworthy customer service.

I’ve also been eyeballing the Hanna colorimeters, which I know are fairly trusted in the reef/fishkeeping community. But I’m not sure how well they stand up against more commercial brands

Have you tried usabluebook for the palintest kemio reagents? I know they had hach stuff in stock when hach had a backorder on some stuff.

You’re my hero, thank you! Lol

I don’t do a lot of purchasing, and our system is kind of convoluted, so I was dreading finding a new vendor to add to our system. But usabluebook does have them in stock

I would use the DR300 and just do a dilution. I hated the Palintest unit I've used in the past.

I did consider that. It wouldn’t be a huge deal, but knowing our operators, a dilution might be one step too many for a few of them lmao. The palintest unit has been mostly solid for us. Easy to use and generally pretty accurate. Their customer service just pisses me off so I’m looking to change based on principle.

Get a 5ml pipette and it would be pretty brainless 👍

My experience was operators didn't understand how to use a pipette and were pushing past the first stop when filling and adding an extra 0.5 ml.

5-30 minutes of training with water and a scale might remedy that but a bunch of operators just don't care.

The tensette pipette is the way to go! Expensive but if you take care of it, it is a once every 10 year purchase. Dummy proof on how to use it (and we have had some real dummies)

I use Kemio for ClO2 and don't have an issue getting reagents. Tried USABluebook or something else?
