calibration

Hi everyone, I'd like to ask for some advice regarding my Jebao MD 4.4 dosing pump. I seem to be having an issue with the calibration. I set the calibration volume to 20 ml. For Channel 1, it took 10 seconds. Then, I moved on to calibrate Channel 2, which took 12 seconds. However, when I went...

So I moved my tank to a new place and I haven't been dosing for about a year because there was not a need. Now im restocking coral and I need to dose to keep my alk even. I hooked up my jebao doser again and calibrated it to 100ml. Ran a test auto dose for 10ml it pushed more than 60ml before I...

I have two inkbirds and they have a 4 degree difference so I need a thermometer to calibrate them. Does anyone use a candy thermometer to check there tank? Or should I buy the Hanna thermometer since those seem highly recommended?

Hi, I was wondering if anyone could recommend a reference solution for nitrate and phosphate to verify my Hanna and Trident NP tester. I know Fauna Marin used to have a seawater reference product but I think it might be discontinued as It says it is out of stock at all the retailers I use. I...

Hello arduino ppl out there! Selling cuz I'm not so patient anymore. Tried to setup and I gave up. Works fine, reads fine. You just need to write a code and calibrate. This means, condition = used (once for.. 30min). One single package with: 1) Industrial grade PH meter 0-14ph. BNC connector...

My Apex salinity reading has drifted over the past few months, not far, but enough to give it a quick calibration. My Hanna gives a solid 35ppm. I'm sure I've previously done a manual calibration where I've just left the probe in the sump and run the calibration - granted, I've not done one in...

Hello everyone I have owned this Kamoer x2sr for a few weeks but I can’t calibrate it properly, I calibrate it but every time I test the pump’s accuracy it never doses the amount I want, I have the pump next to my reef tank, waste water goes down to my basement directly to the drain and my fresh...

So I just purchased the new Hanna Marine Monitor that has a PH probe and a Salinity/Temp probe. The unit continuously displays the above and uses temp to accurately calculate it’s readings. I hooked the unit up and followed the instructions on how to use the included 7.1 ph solution satchets and...

I asked Neptune about my trident being off from other test kits and they told me I have to test the test kits to the calibration solution that is provided by Neptune in the trident dosing solution to compare how off they are to one another. this seems very logical and a way to calibrate your...

I keep seeing people claim the salinity probe is trash and/or it cant be calibrated. I keep giving the same steps on FB for people to follow and figured I would post them on here as well. For the salinity probe calibration do these steps for the best accuracy/stability. 1. Ensure the cable and...

Okay so Hanna's Digital Salinity Meter requires calibration right? Could Hanna produce a Checker that did not require the purchase of calibration solutions? For example if a Salt Mix Pack says "Mix 1g of salt to 1 liter of water for 35ppt" Bearing in mind Hanna Calibration solution is 35ppt, you...

Hello Everyone, I'm curious out there if anyone has had similar issues. My Neptune trident, out of the box, was testing close to my Hanna checkers. After running the unit until the reagents ran out, that's when the calibration issues started to occur. Magnesium and calcium were very off. I...

For ORP I found this - https://www.bulkreefsupply.com/pinpoint-orp-redox-400-calibration-fluid.html I assume it will work - even though it is not a Neptune specific product? For Salinity I know this will work -...

I had a heck of a time getting my (brand new) Neptune probe calibrated. I had to send it in for "diagnostics and repair." While waiting, I purchased a Milwaukee probe and BRS probe. Once the Neptune probe was returned I tried all 3 and all 3 calibrated well. But would eventually drift...

So I tried being a responsible reefer today and decided to clean and recalibrate my pH probe. Well afterwards the reading is now significantly off. My pH is usually 7.9-8.1, my pH probe is now reading 7.47. It’s strange because when I have the probe in the different calibrating solutions...

Hi to all! I just recently purchased my new Apex and so far I absolutely love it! But, the only problem I am having is that I can’t get my salinity probe to calibrate. When I’m calibrating on step 4 it just times out and can’t seem to get the correct salinity range it needs. Is there any...

Does Hanna offer calibration fluid, so I know my Alk checker is reading accurately. And if so, and the reading is off, how to calibrate? I'm using the HI 755 ppm Alk checker with the HI 755S reagent

Are you properly calibrating your refractometer? Lot of people just use RO/DI water which will read 0..however your not going to get the the most accurate results. the next batch of people will use proper 35ppt/1.026 calibration solution which gets you closer.. but ar you taking into account...

I bought My APEX 7 month ago. I want to know if I need to recalibrate my PH Probe and how often? Thank you in Advance
